The Beast – The Jardim Special - 1968 – 1972
In the middle and late sixties there was tremendous enthusiasm for motor
racing. My brother Alan and I were young men in our early twenties, in
love with engineering and fascinated by motor racing. We were also
penniless, so the prospect of actually taking part in some way in motor
racing was remote. The race meetings of 1968 changed all that, as
Kenneth Veerasammy’s Kenveer Associates had imported a Lotus Super Seven
which was driven by Eric Vieira in masterful fashion. Later that year,
space framed U2's and Lotus Super Sevens came from Antigua to reinforce
what Eric had done, and also to show quite clearly that light and simple
space frame Clubmans cars could compete with the best and fastest, and
at a fraction of the price.
Thus encouraged, Alan and I pooled our savings and set about building a
Clubmans car. The design had started life as a takeoff of the Chapman
designed Lotus Super 7, using the Hillman Minx engine and running gear
we had inherited when Alan bought a crashed Hillman Minx. Because he
wanted to use the Hillman front seats so the car could be licensed and
driven on the road, (we didn't have any others, and we had no idea how
to make seats), the car became quite wide. It soon became evident that
the Minx 1,496cc engine did not have enough horsepower, and so on a
whim, Alan approached Compton Pooran, who was then the head of Sandbach
Parker's motor division. Compton generously provided us with a longer
stroke crankshaft which took the engine to 1,725 CC and the grand total
of 88 BHP! Nevertheless, the tubular chassis we had built weighed only
85 pounds, so the car was impressively quick, and even on narrow 13 inch
wheels went around corners like it was on rails.
The first recognized GMRC driver to become interested was Conrad
Williams, who in those days was very quick in a screaming Honda S800
sports car. We took the car to the circuit and Conrad did some fast
laps. He was quite impressed with the acceleration and cornering but far
less impressed with the drum brakes at all four wheels which quickly
lost any stopping power after a lap or two. Fast it was, but it was no
Honda S800, prepared in Japan.… We simply didn't have the money to
correct the obvious shortcomings so the project languished for a few
months.
Alan, ever the go-ahead type, felt that we would never attract any
drivers without creating some excitement and felt that the way to
provide excitement was with lots of power in a very light car. That
would attract drivers and sponsorship, which would allow us to buy the
brakes, tires and other requirements for a credible racer. The list of
expensive racing components was of course endless, and also endlessly
expensive, but we decided to go ahead.
Alan decided to fit a Ford 292 cu. in. V-8 we had bought for scrap. He
disassembled it and found that there was very little wear. He rebuilt it
carefully. The engine started easily and ran smoothly, and made a most
impressive roar. Being penniless, we mated this V8 to a shortened
version of the Hillman Minx gearbox, which had an output shaft of about
3/4 in. diameter (the size of a finger), and to the Hillman rear axle.
In testing, the car was brutally fast, but neither of us was a racing
driver, able to put the gearbox and rear axle to the test.
We interested Danny Fraddette, who was a moneyed young man about town
and a talented driver. He had had much success driving his Lotus Cortina.
Danny negotiated with Central Garage for Dunlop sponsorship, and ordered
1968 Formula One tires. When these arrived, we, and practically everyone
else, were goggle-eyed. No one had ever seen rubber this massive. We
duly widened the rear Chevrolet and front Viva rims to accommodate them.
This was the beginning of the engineering uncertainties that have always
been a part of motor racing. Make it heavy and safe and you never win
anything; make it too light and you risk losing everything. Even the
simple widening of rims to take racing tires brought into question
serious concerns about the strength of lug bolts and the surrounding
metal of the rims. It was not only that the Ford V8 engine was extremely
powerful, but also that it displaced 5 Litres, and had the torque of a
steamroller. We were very concerned, and mostly erred on the side of
safety. The eighty-five pound chassis began to be a thing of the past.
We allowed Danny and Martin Nascimento to take the car up to the circuit
and try it out. Danny did most of the driving, and seemed to be duly
impressed but it was hard to know whether to take him seriously, or
whether he was just being kind. What was serious, was that there was a
loud big end knock from the V-8. The crankshaft was ruined. We had never
anticipated the problem of severe oil surge, and under the hardest
acceleration out of the Gooseneck, and all of the way up the following
straight, there had been no oil pressure. We could hardly blame Danny
for feeling that although the car had potential, he wasn't going to wait
around for us to get it right. Nothing more came out of this
association.
At this point, in early 1969, Martin Nascimento who had raced at Brands
Hatch in England and at the South Dakota Circuit, and who had been
loosely involved with Danny in developing the car, said he wanted to
drive it himself. He was very enthusiastic and would frequently find
parts that we asked for in a matter of days by putting the touch on some
friend. Like his brother Kit, he was very much a people-person. He was
also a genuinely nice person to deal with. His positive can-do attitude
leapfrogged all difficulties.
We took the car to Timehri and did some testing and he was full of
praise, though I could see that he was concerned about safety, something
which had been low on our list of priorities as we struggled to put the
car together. He wanted to build up the sides of the cockpit, and was
concerned about the steering column (we later dog-legged it). In the
event, we didn't do very much about these things. We probably did not
know where to begin. The best we could do was to make a very strong
rollover bar, and to shield the driver from the drive line.
We agreed to have the car ready for the November 1969 meeting and went
to the circuit for the Friday practice session with Martin to do some
preliminary testing. The car was a handful on the straight, especially
under braking. In those days, it was assumed that very light cars on the
bumpy surface of the long circuit were always going to be a handful. U2
drivers used to tell me that they frequently could not guarantee whether
they would go under or around the Dunlop Bridge which was at a part of
the long circuit where you were going fastest just before braking for
the entrance to the Gooseneck. Said as a joke, it was no laughing
matter. Our tachometer and gearing said that we were doing better than
140 miles an hour at this point.
I had had more than a suspicion that the front-end geometry was
providing a large amount of bump-steer but somehow had put it out of my
mind so I began to file down the rear brake shoes on the Hillman Hunter
axle to reduce their braking area in the hope that it was the rear
brakes that were locking first and making the car fishtail. Vain hope.
On one of the practice laps after this, Alan and I were standing at the
exit of the low speed bend where we hoped to see what the car did under
braking, when Martin approached at high speed, probably 120 mph, and got
on the brakes. The car struggled from side to side violently, and
finally he let go of the steering wheel, hands in the air, and
disappeared up the sandy escape road at probably 80 miles an hour. I
felt sure that he would run into the trees with fatal consequences but
the next thing we knew he was reversing out, sand and dust pouring from
the rear wheels. Later on that afternoon he got down to a respectable
time as though nothing had happened, instability and all.
The next morning, I resolved at least to remove the worst of the problem
if I could not completely cure it. I did this by getting longer Pitman
arms and heating and bending them to fit the Vauxhall Viva steering
knuckles. I had to heat them to bend them but did this with great
concern, because the heating and cooling of the steel forging could
easily have crystallized the metal at that point and made it brittle. I
got two other arms and did the same heating and bending with them, then
tried to see if I could break them in a hydraulic press. They didn't
break right away, and when they did it was at an enormous tonnage. This
meant that the Pitman arms would only break after all the suspension
members had been ripped off. Some reassurance, but I was glad of it.
Thankfully, the modifications did seem to make the car at last drivable.
We qualified well for that November 1969 meeting at one minute
twenty-eight seconds, fastest of the local entries, and beaten by only
the Twin Cam Escort of Englishman Mike Crabtree. I remember standing
somewhere by the entrance to the pits and seeing Martin blast by, the
V-8 roaring and echoing off the pit walls, the sound echoing and singing
through the trees as he climbed the slight hill up to the high speed
bend. Every lap, I would wait and wait to hear when he would lift off
for the bend and it always seemed as if he kept the power on another two
or three seconds. In the afterglow of that Saturday practice session,
second-fastest time of the day, we had great confidence and there was
quite a buzz in the clubhouse over this powerful upstart who had
leapfrogged all the other local competitors. Martin, flushed with
enthusiasm, there and then nicknamed the car "The Beast".
Race day however was another story. Martin started from the right side
of the first row of the grid, and it was easy to foresee what would
happen next; in the noise and confusion of the start line, he revved the
V-8 hard and popped the clutch, breaking the rear axle spider gears and
locking up the axle, which broke the gearbox. Reminiscent of the BRM in
its first race, the Beast barely rolled five feet. It was a great
disappointment for Martin who was shortly to leave for England and a new
career, to have victory snatched from him, but Alan and I were elated by
the events of the entire week, when two 25-year-old kids had stuffed it
to the establishment. We were now firmly accepted. The unlimited sports
car races were won by Mike Crabtree in a Twin Cam Escort, with Arnie
Poole in an MGB second. This was said to be a "Le Mans" MGB, which was
not very convincing at about one minute twenty-six seconds. We were
sorry to lose Martin, who was a very fine driver and test driver, and a
fine person too.
With Martin's departure, Eric Vieira appeared on the scene, determined
to drive the car in the April 1970 meeting. Eric was some 15 years older
than Alan and I, and was a legend in motorcycling and car racing. The
first few times he came to see the car we actually called him "Mr.
Vieira".
Eric took the car very seriously and so did I. Knowing that the gearbox
was not strong enough Eric obtained a four-speed manual gearbox from an
American Mustang V-8, the last word in heavy-duty V-8 transmissions of
that time. This actually had a Hurst shifter, some of the crudest
ironmongery ever designed to shift gears. This gearbox too had to be
shortened, as we had moved the V-8 rearward until the car was more mid-engined
than front engined, in an effort to get more power to the road, but it
was less problematical than the Hillman Box. The shifter itself was a
different matter and had to be linked forward as the gearbox, shortened
to the minimum, had a driveshaft only ten inches long to the rear axle.
Shifting was always a big guess, and whenever Eric would fail to get
third gear, downshifting from fourth for a corner, it would inevitably
result in a lurid spin. For a while, we actually dispensed with the
Hurst Shifter and put a dog- leg in the “gear stick”, so that shifting
was more up-and-down than fore and aft. Crude, but it did work.
The biggest problems were unsprung weight, and the inadequate Hillman
axle. The structure of the car was quite light compared with the
massiveness of the engine and transmission. Any solid rear axle strong
enough to accept the engine torque would have been far too heavy both of
itself and as unsprung weight, and on the rough surface of the long
circuit it would have been almost impossible to keep the wheels in
contact with the road. Inevitably, we had to opt for independent rear
suspension with inboard disk brakes, in an effort to move as much weight
as possible inboard. This allowed us to use a rather massive 3.55:1
final drive, but meant that designing the rear end of the car would be a
feat of engineering. Doing this design nearly exhausted us, because of
the inherent contradictions of working with a saloon car differential,
but the execution, which included the making of splines and heat
treatment was even worse. I was also under great time pressure, having
to go to England on business shortly after. Eric was very resourceful
and helpful, scouring the storerooms of Bookers Agricultural where he
worked, for suitable universal joints for the half-shafts. We went
through at least two versions of the independent rear. One practice day,
after Eric had done some very creditable times, over maybe twenty laps,
he came in, and pronounced the car excellent. “Don’t touch anything!”
Someone suggested he should practice some starts… on the first attempt,
the rear half shafts wrung like pretzels, depositing bits of outer
universal joints on the tarmac… Back to the drawing board for Mark II!
One depressing day, when I said that the maximum size of shaft we could
use was still not going to be sufficient, (we'd already made them) Eric
suggested that we harden them. We heated them and did the most violent
quench we could in cold water, (not a very nice thing to do to a piece
of high tensile steel) but though they improved, they still were not
hard or strong enough. He asked what we could do and I said
half-jokingly that we could quench them in brine. Taking me seriously,
he hustled off to the neighborhood shop and came back with 5 pounds of
salt. With nothing else to do, I reheated and quenched the shafts in the
brine. They were now impressively hard, but I told Eric there was an
increased likelihood of failure from cracks. He Said, "Let me worry
about that!".
Eric in his usual can-do way insisted on driving the car as soon as
possible. The design of the lower wishbones was less than optimum, and
Eric had supplied four Triumph Motorcycle rear shocks for the
suspension. It was all he could find at the time, and we hoped that four
spring- shock units would be enough. When the weight of the car was put
on the shocks they bottomed out. I was also very unhappy with the
strength of the 5/16" shock upper and lower mounting bolts (which there
was no way of changing), and my own harried and immature design of the
lower wishbones. Never enough time, never enough resources.
Trying to save valuable development and practice time while I was in
England, Eric tried to run the car prematurely . On his way up to the
racetrack at Timehri, he spun in the wet, and then phoned me in England
to tell me of the near disaster when an oncoming truck narrowly avoided
him. In those days, people routinely drove race cars on the road. The
police were generally very understanding. Most were race fans. Eric was
definitely the bravest driver I have met, and had the stuff (and the
technical knowledge and talent) to have been world-class.
Looking for more speed for the April 1970 meeting we decided to use
eight separate exhaust pipes, one for each cylinder, of 1-1/4 inch
diameter stainless-steel. These had come from a sugar factory and were
full of scale which we had to remove by heating the pipes cherry red. If
this were not enough, bending them required filling them full of molten
lead to avoid kinking, then melting the lead out after bending. It was
massively time-consuming but it had great cosmetic value, as we buffed
the stainless steel pipes to a high sheen. These exhausts were fitted
under Eric's house in Courida Park, not least because the Barbadian
racing team was staying next door and we hoped they might be
intimidated. Every bit counted!
A few weeks prior to the November 1970 race meeting, looking to get in
some experience and practice, Eric insisted that we should do some early
morning runs, and said that I could meet him at the circuit on my way to
Mackenzie on business. Joey King and Eric's wife June were there to lend
support. Eric proceeded to make some rapid but inconsistent laps of the
long circuit, the car looking very ragged and Eric stopping to make
understandably ragged comments every other lap. Finally, he lost it in a
big way on the high-speed bend and entered the trees at speed. The car
was full of sand from having slid sideways but apart from this there was
no damage. It was admittedly very difficult to drive fast and this was
his first full session with the Beast.
The car was not impressively fast at 1 minute 25 seconds for the
November 1970 meeting but was faster than almost anything else in
Guyana, so we had a respectable place in all our races and were part of
the establishment. I particularly enjoyed driving it around on the lap
of honour at every meeting while Eric, as club president escorted the
club patron, impressing my friends and scaring myself at its brutal
power which I knew quite well I could not hold flat-out for a full lap.
At the April 1971 meeting, the stainless-steel individual exhaust pipes
kept breaking off from fatigue failures at the welds. The car was not
very fast, at best 1 minute 24 seconds.
In those days, Eric was generally regarded as the bravest and most
talented racing driver around, and insisted on entering a Club Day
Meeting which I thought was not worth the trouble and expense. The real
trouble was that Eric's energy and have-a-go spirit were up and we had
to go, regardless. During the race, about three laps from the end, one
of the oil breather hoses came off of the valve cover and the engine,
which already had a severe oil control problem because we had never been
able to cure completely the oil surge problem, began to blow hot oil
mist back over Eric. He was being badly burned and could hardly get a
grip of the steering wheel or gearshift, and with oil all over his
visor, how he saw anything was a mystery. He certainly could not move to
avoid the oil spray in the cramped cockpit. Nevertheless he kept on and
crossed the finish line first, jumping out of the car before it stopped
rolling, and rolling himself in the sand to get rid of the hot oil.
The car's performance in the April 1971 meeting was so unconvincing that
for the November 1971 meeting it was thoroughly rebuilt, with much
additional diagonal bracing. It became a great deal stiffer and lower,
but also heavier. All bodywork above the frame rails was removed and the
radiators were mounted nearly horizontally in the nose. The front
suspension was completely redesigned and rebuilt to cure the bump-steer,
and the rear suspension lower wishbones became parallel links also to
improve directional stability. (Three years later at a Grand Prix
meeting at Brands Hatch, McClaren were proudly showing off this new rear
suspension design on their 1974 Grand Prix car. We were chuffed! In one
of those unaccountable racing developments, the original front
suspension of the Beast, circa 1968, used horizontally mounted inboard
springs for better control and lower unsprung weight, a development that
was not seen in Grand Prix cars until the eighties. But we could not get
sufficiently stiff springs for it, and had to abandon it for a new
design using outboard spring-shock units in 1970). The New front
suspension used knuckles and disk brakes from the MGB of Peter Willems
who had written off his car, and who gave us all the parts in exchange
for me doing some small amount of work on the crankshaft of his
Marauder. The larger brakes made the world of difference, and we no
longer suffered from boiling brake fluid. Such was the generosity and
spirit of enlightened competition of people like Peter. The Beast
contained parts from many cars and Guyanese companies, almost all given
for free…
We built new exhaust headers of 1-3/4 inch tube with three inch
collectors. Because we could not bend thin wall tube, this involved
sectioning every bend of tube from various exhaust pipes we had gotten
from Philip DeFreitas at Central Garage. This took a complete week of
hard labor (at this time I was conscious that my father was saying that
we were going to lose our company if we kept on) but the result looked
and sounded impressive, painted in white and red Sperex heat resistant
paint. It also definitely added horsepower. Philip DeFreitas had been a
constant and generous supporter, and supplier of parts, even though we
competed against him. The Beast raced on 13” Minilite Magnesium front
wheels that he’d very kindly given us.
.
Alan and I fitted a new ignition system, as we were sure that the
standard distributor could not keep track of the 7,000 RPM we were
using. With a standard crankshaft we must have been crazy to do this,
but we never suffered a crankshaft failure. I made a gearbox which
geared two four-cylinder distributors together at right angles, and Alan
fitted dual capacitor discharge ignitions. This modification alone
transformed the car. We now had separate ignition systems for each bank
of four cylinders. We had not realized that large-bore V-8's required up
to 45 degrees of ignition advance.
While the rear suspension was off, Alan thought that he would test the
engine with the new ignition system and timing while applying the
inboard rear brakes as hard as he could. I remember sheets of fire from
the brake pads as the brake rotors glowed cherry red after only two or
three seconds. We were elated. No disc brakes could hold this engine!
Eric had also enthusiastically imported an Iskendarian camshaft which
had an outrageous duration, which Iskendarian themselves claimed was
useless below 4,000 RPM and topped out at 7,000. For our part, we had
polished and ported the heads and surface ground them until we had a
compression ratio of probably 11:1. We didn't care that we were going to
unleash all of this on a standard cast-iron crankshaft. We didn't care.
We clearly had the power now!
Eric said that he preferred not to think of all this mechanical violence
two inches away from his left knee, and that at any rate, he couldn't
think of any such thing while flying up the back straight and planning
the braking for the high-speed bend. In the cockpit, there was almost no
place to put any shielding. The engine had had to be offset six inches
to the left to accommodate Eric, and even so, getting in and out was
quite a job. The fit was so tight that the pedals had to be mounted on
their own movable pedal box, if there was to be any prospect of
adjustment for the driver's position. I remember Eric headfirst down in
the foot-well carefully bending the accelerator, so he could
heel-and-toe.
Around this time we became very friendly with Rod Grimes-Graeme and his
partner Tom Wilson, who operated InAir, out of Ogle Airport. These two
were true racing enthusiasts, and genuinely shared everything with us,
promoting more competition. Rod had bought and was driving one of the
Antiguan U2's, and Tom Wilson had completely rebuilt another U2 and
fitted a Lotus Twin cam engine. The car was a joy to behold. Tom was an
aircraft engineer, and brought his high standards to everything he did.
No fluid line or cable went without a nylon tie or a restraining cleat
screwed to the chassis. All fluid lines were Aeroquip, and the bodywork
sheeting was aircraft Alclad, neatly riveted, or held in place by Dzus
Fasteners. This had immediate effects on us, as much of our work was
quite serviceable but rather agricultural, and we began taking parts off
of the Beast and reengineering them to the new standards. Rod and Tom
also lent and gave us many components which we simply could not have
obtained otherwise. The most important thing though, is that they took a
professional approach to their racing and immediately began to look for
sponsorship. This materialized in the form of the Demerara Tobacco
Company. Ltd. who agreed to sponsor a three-car team, to promote their
Embassy cigarettes. Rod and Tom generously invited us on to the team,
Team Embassy. Tom, in his usual excellence, painted all three-cars in
the white, red and gold Embassy livery, with impressive graphics and a
high standard of finish. They looked too pristine to be raced. DEMTOCO
themselves, knowing public relations as they did, arranged for the three
cars to be displayed in the lobby of the Pegasus. It was highly
successful, and caused a lot of favorable comment.
Two Saturdays before the November 1971 race meeting, when Alan and I
were hoping for a rest from working on the car, which had become a
six-month-long operation, Eric came to the workshop and suggested that
we take it to the circuit for practice because Rod and Tom were going to
be there with their U2's to offer competition. We were all very tired,
but we went down to the Pegasus and got the car out of the lobby. The
car had been taken to the Pegasus hotel where it was on display so we
had to go there and retrieve it, something we had not planned to do for
a week. I remember actually fitting a variable diameter pulley to the
water pump right there in the Pegasus lobby before we took the car out.
We had custom-made the variable pulley the night before, as there was no
room for a tensioner pulley and the car had no alternator.
The car looked pristine on its arrival at the circuit, and Eric set off
to do some pretty quick laps. After awhile he came in with severe
overheating problems and we realized we would have to abandon our new
aerodynamic nose and open some exhaust flaps in the bodywork.
A few laps later, he went missing and someone rushed into the pits to
say he had had a huge accident in the high-speed bend. Alan and I went
out to see what had happened with the greatest misgivings, to find that
the car and Eric were undamaged in the accident but, to our great
dismay, it had lost its left rear wheel under braking. The wheel had
barely missed hitting a Marshal, Tony Dias, and had gone into the trees
so hard that it had bent the rim, even though the tire remained fully
inflated.
We used the Taylor Woodrow truck-mounted crane to retrieve it and took
it back to the shop, where Eric immediately insisted on finding a
solution. I was in a state of shock, as I knew only too well what would
have happened if the half-shaft had broken at full speed on the straight
on race day. Eric would have been in big trouble to say the least, but
probably also many spectators could have lost their lives. There was not
a word of concern or complaint from Eric, nor did he give the slightest
hint that he might reconsider racing the car, after having lost a wheel
at 140 miles an hour. He simply asked me if I could make it stronger,
and said he would accept whatever I did. Not an easy thing to deal with.
Eric drove us all over town from junkyard to junkyard and we finally
found one that had old Ford half shafts, which we bought right away.
When we looked at the broken shaft, we realized that the Ford Motor
Company had not left any fillet radius where the bearing butted up
against its shoulder. We had simply assumed that they knew what they
were doing. My best solution was to make a very large fillet radius to
the axle flange, and to make a large radius washer to go up against it.
We then polished the fillet radius to a mirror finish. I did this with
grave misgivings because I felt that the axle was nowhere near strong
enough for the 300 horsepower we were putting through it. It was at most
1-1/8 inches in diameter and not heat treated at that point. Good enough
for a 5,000 pound American car, but probably not good enough for an
1,800 pound racecar. No way of knowing. Nevertheless, it never failed
again over many races, and many spins, and the harassment of racing at
the small and tight bushy Park circuit in Barbados. Perhaps my innate
conservatism paid off. Perhaps.
Eric prevailed, and the next Saturday, the car was back at the South
Dakota circuit for practice. In the meantime, Alan had reset the
electronic ignition and we did one minute 21 seconds in practice, faster
than anyone else, including the English racing team.
On race day, Eric's determination and bravery really shone. He led the
race from the second lap, taking the lap record lower and lower every
lap, until he set best time of the day and the outright Long Circuit lap
record at 1 minute 18.1 seconds. We had not realized that there was such
a Guyanese following for a Guyanese car driven by a Guyanese driver. Lap
after lap, people waved shirts, towels, anything that came to hand; they
danced and slapped one another on the back until he crossed the finish
line, winning by the proverbial mile. We all had a great party at the
clubhouse then went home in a state of euphoria which continued all
week, as congratulations flooded in and more parties were held.
Subsequently, Eric was named Sportsman of the Year, and awarded the
Medal of Service for his services to motor racing. Eric's time with the
Beast was only part of a hugely talented, generous and brave commitment
to motor racing over many years. He richly deserves the success and
recognition he has gained. For our part, Alan and I gained a great deal
of respect for our engineering. The Beast put us squarely on the map. We
were more than amply rewarded. It was truly a golden time for us all.
PostScript:
The Beast was a triumph of development over lack of money and access to
racing-quality components. In the late sixties and early 70’s, by the
time one located a part, probably in a magazine, ordered it, had it
shipped and actually received it in Guyana, an entire year of racing
could pass. And information was always hard to come by.
In many areas we were simply on our own because we were having to do
things that others in the developed world did not have to think about.
When in 1968 we could not obtain suitable spring-shock units for the
front suspension, we had to design and make inboard pushrod suspension.
The lack of suitable gear boxes and final drives meant that we went to
ridiculous lengths to design independent rear suspension with inboard
brakes; and being unable to choose brakes for the front and rear in
suitable proportions meant having to design proportional braking
leverages, a task made doubly hard by the lack of master cylinders of
suitable sizes. Even this was not sufficient, and we were finally forced
to add vacuum boost to the front brakes, only to achieve the correct
balance. This was an unheard-of situation, as even Formula 1 cars were
able to get by with simple braking systems which did not need power
boosting.
The engine in its the original configuration could have competed
successfully with a single four- barrel carburetor, but the only one we
had had very small choke sizes. Out of redundant stock at one of the
garages, we found three two-barrel carburetors, but then we had to
abandon the original intake manifold with all its water passages and
fabricate our own lightweight manifold for the carburetors, and deal
with the difficult issues of a sensible and responsive throttle linkage,
and how to get six individual carburetor throats to dispense mixture
equally to eight cylinders. Eventually, Eric pronounced the system
undriveable, and the day was only saved when he acquired a very large
Holley 2750 carburetor with 2 inch chokes from Hammy Green, who had a
large Pontiac at the time and gave the carburetor without question. Even
the politicians were involved! While others could get away with a light
and simple throttle cable, we were forced to build a system which went
around the front of the engine and used stainless steel pushrods and
aircraft 3/16 inch ball ends in order to get sufficient responsiveness
from the throttle. Either that, or miss gears, or spin off the circuit.
The list went on and on, complexity begetting complexity and adding
weight.
We succeeded mostly because both Martin Nascimento and Eric Vieira after
him, were masters at obtaining good substitutes, through their own
knowledge of the local garages and technical ability, and through sheer
social prowess and a can-do attitude. In addition, totally impossible
situations like the cutting of splines in high tensile steel shafting
were salvaged only by the exceptional skill and knowledge of Doodnauth
Gangaram, who was the leader of IEL's machine shop at the time. I would
frequently design a component to cure some impossible problem, knowing
full well that it was probably beyond our capabilities, but Doodnauth
would say, " Well probably not this morning, but how about by midday?"
Such was the innocent magic of racing in the sixties and early
seventies. Guyana still had highly skilled and committed people, and
those in racing generally had a high-minded vision of competition. If
you did not help your competitor to be competitive, you were going to
have a very hollow victory, and motor racing itself would die.
In early 1972, we took the Beast to Barbados to race at Bushy Park.
Peter Ullyett, a Barbadian who lived and raced in Guyana was a great
enthusiast, as was Ralph "Bizzy" Williams. Ralph had been a large part
of the building of the Bushy Park circuit, leasing his family's land to
the club for the purpose. Peter provided the enthusiasm and drive to
make the visit happen.
As it turned out, because of lack of space, the Bushy Park circuit was
extremely small and tight, and a good 100cc Kart of today would probably
be far faster than even the Formula Caribbean 1600cc cars of the era.
The Beast was very unsuited to the circuit, and looked like a
muscle-bound wrestler in too small a ring. In fact the wrestling was
mostly done by Eric, who hurled the Beast around bushy Park to the
accompaniment of much manhandling of the wheel from lock to lock and
incessant second-third-fourth gear changes. This violent style was very
different from what we had been accustomed to on the long straights of
South Dakota, and we paid a price in mechanical failures and being only
third or fourth fastest.
On the Saturday morning at practice, Eric must have had a can of
"Commanding Oil", as he willed the Beast to go faster and faster when it
clearly was already beyond its limits of adhesion. On the left-hand bend
which went pass the infield on the back of the circuit he left the road
completely and charged across an onion field, colliding with a welding
set and oxygen bottle being used by the crew who were building the
observation tower. There was a loud roar of escaping oxygen as the
regulators broke completely off, and chaos with workmen dashing madly to
get out of his way. Surprisingly, yet again there was almost no damage
to Eric or the Beast, but the car was filled with large and delicious
onions which Peter Ullyett turned into steak and onions that night at
his house where we were staying. The next morning, we were all much the
worse for wear, all having gone back to the circuit to continue working
on the cars. We were awakened at 5 a.m. by Sam Cyrus, disgusted at our
laziness, crowing loudly like a rooster. Motor racing was also filled
with larger-than-life characters.
After the huge success of 1971 and the equally huge emotional stress of
working to racing deadlines and having to accept large risks, Alan and I
took a decision to stop developing the car, hoping that it would just
fade away. Although we had had excellent publicity, our business had
suffered badly, and 1971 showed the lowest annual turnover in three
years. We weren't broke, but we would clearly have to start paying
attention. We decided that we would build lighter and less complicated
single-seaters, for the Formula Caribbean that was just starting up. (In
1974, we went racing with Eric again with a single-seater rear-engined
Terrapin).
In mid-1972, we had however reckoned without Eric. He was still as
competitive and race-ready as ever, now in his early forties, and was
soon back at IEL encouraging us to look for more power for November
1972. There was no way of getting more power out of the V-8 without
blowing up the engine, but this was after all an Unlimited Sports Car.
It so happened that we had a Rootes-type supercharger at the shop which
we used to use for pressurizing large steel fuel tanks when testing
them. It would be completely within the rules to supercharge the V-8...
There were some problems: To supply enough inlet pressure, the
supercharger would have to run at 10,000 rpm, and we doubted that it had
been designed to do that. Secondly, there were no toothed belt pulleys
or toothed belts to be had, so we had to use timing belts from a
Vauxhall Victor, and mill the pulleys from solid aluminum billet. The
available belt centers also meant that the supercharger and its intake
manifold and intake trumpet sat very high on top of the V-8, so the
driver's line of sight was problematical.
Eric and we accepted all of these drawbacks and took the car up to
practice. It was immediately clear that we had an astounding amount of
power. The Beast would exit the Gooseneck in a cloud of tire smoke and
keep on smoking all the way up to the clubhouse. Unfortunately, when
Eric backed off the throttle for the high-speed bend there would be a
violent explosion in the intake manifold which would rip the drive belts
off. Whenever we managed two or three clear laps, intake manifold vacuum
on the over-run would suck all the lubricant out of the supercharger
bearings.
We didn't realize that these problems were well-known to the drag-acing
fraternity who used superchargers, and we didn't have the time or
resources to solve them, so in the end we had to abandon the effort and
revert to naturally aspirated form. After a few more successful
appearances, including humbling the Brabham Formula 3 (running without
carburetor restrictor plates) of Antiguan Jimmy Fuller, (Eric passed him
exiting the Gooseneck on the last lap as Jimmy spun, but himself spun in
the low-speed bend and was unable to restart), the car ended its South
Dakota racing days at the end of 1972, and was sold to Lucien Tie-Ten-Quee
of Jamaica, who had raced a Yamsel motorcycle at South Dakota.
Bobby Hunter reports from Jamaica that Lucien raced the car in Jamaica
for a few years and won many races with it before suffering a failure of
the rear differential subframe. This had always been a weak point,
(requiring a few anxious repairs at Bushy Park, Barbados in 1972), as
the slender frame, and the differential attachment bolts, had to
withstand more than 1,500 Lbs / Ft of torque from the monster of an
engine, when multiplied through the final drive.
Lucien then sold it to another enthusiast who changed the aerodynamics
and lowered the suspension. In its last race, the car bottomed out
heavily and probably fractured the engine block, losing all its oil. The
car's whereabouts unfortunately can no longer be traced.
