the wheel for the maiden run

Ron Lutz
talked with Trojan and BMC Competitions Department about supplying a car
and suitable engines, and once the Le Mans entry had been accepted the
project was underway. The Elva Courier Mk.4'T' Type was ordered on the
7th November 1963 and was ready at the end of January 1964. The car number
E1137 was actually a rolling chassis with unpainted lightweight (two layer)
body, but complete with the differential, gearbox, two engine blocks and
umpteen special engine tuning parts.
The first
job was to saw off the nose of the body with the view to improved aerodynamics,
much to the chagrin of Mr Peter Agg, the Managing Director of the Lambretta-Trojan
Group, who had contributed to the design the car. There was another reason,
as Ron had persuaded Trojan to supply the incomplete car, without charge.
The deal was for the car to obtain good Press coverage by running in this
important race, and in that event Peter and his company would be very
happy. However, if the car did not run, then it would have to be paid
for, or returned to the Trojan factory. A similar agreement was made with
'BMC' over the engine parts supplied.
A team organiser
would be required, and Chuck Foster agreed to help keep everything together
to ensure that people, parts and paperwork were all in the right places
at the correct time. Not an easy task.
A home was
rented with a large basement garage plus a suitable side room for the
engine builds, and various friends were recruited to help, as everything
had to be done at weekends, or whenever the 'day' jobs allowed. Dick and
Ron were involved in the electronics industry, but they soon found 'Red'
Earl to help with the glassfibre work, and Jim Taylor was appointed as
the automotive electrician. Tony Corrado produced the 'elephants toenails',
or lamp covers, using the domestic oven to achieve just the right shapes
with ingenious moulding and heating methods and great timing. Soon the
nose was reshaped to everyone's satisfaction and all that as needed was
some horsepower.
The BMC engine
blocks were special castings with extra thickness around the area of the
cam-followers. The standard pushrods would not survive the high revs anticipated,
and so sturdier pushrods and cam-followers from a Buick V8 provided the
answer. Again, a bore to 2 litres and Hepolite racing pistons were used,
although it was also necessary to machine 1.5mm off the face of the blocks,
while the induction was care of special Derrington inlets for the 45DCOE
Weber carburettor.
A technical
college in Angers was encouraged to electronically balance the crankshaft
and flywheel assemblies as part of a class project. They did a wonderful
job as both assemblies were balanced to spin, vibration free, up to 10,000
rpm. The likely maximum was to be 7200 rpm but as an addition engine safety
measure, high output oil pumps were ordered from Australia.
The first
completed engine was installed and it immediately blew off the oil filter
housing. Next time it pumped up the oil cooler like a rugby ball and after
much head scratching it was discovered that the filter bypass hole had
been inadvertently plugged. After this and a few other minor maladies
were fixed, the car made a perfect maiden run.

Although
the car was supplied as a roadster, the team had decided that it should
become a fastback coupe, and so a simple prototype hardtop was fashioned
and fitted before the car was taken for a 'shakedown' run at the Monthlery
circuit near Paris, in mid March.
The circuit
managers were only allowing the oval, steeply banked 'Anneau de Vitesse'
part of the complex to be used, but Dick took the car up to the maximum
rpm limit and saw over 126mph. However, the project very nearly came to
an early end when he experienced a rear tyre blow out at top speed, but
that near disaster was avoided and the car returned to Jaunay-Clan for
further race preparation. There was to be a two-day pre-race trial for
Le Mans entrants on the 18th & 19th April .
