Braithwaite - Caterham 7
car was built during the winter of 1998/99 and first registered
in April 1999. Primarily it was intended as a road car which could
double up as a trackday / speed event machine as required. The initial
specification included a Ford 1700cc BDA engine running on 45DCOE
weber carbs, 5 speed Ford gearbox and Ital based live axle. Soon
after starting to seriously drive the car it was decided that fuel
injection was an essential addition to solve several driveability
issues. A 45mm parallel Jenvey / MBE throttle body kit was sourced
from SBD and mapped by Steve in late 1999. The car completed the
2000 and part of the 2001 hillclimb seasons with the same basic
setup before a serious internal engine failure meant a change of
the parallel Jenvey throttle bodies, MBE ECU and fitting a Vauxhall
XE 2.0 litre engine seemed a sensible approach as the system worked
very well on the BDA with good performance and minimal maintenance
, Besides , Steve had been hassling me for years to change to
a Vauxhall engine!. A good secondhand unit was purchased from
a local breakers and fitted during the remainder of the 2001 hillclimb
season, finally being completed in October 2001. The basic powertrain
specification was to the SBD 196 kit with a few installation modifications
of my own.
2002 season proved to be a successful one. The car won the Hillclimb
& Sprint Association Speed championship class for Modified
Production Cars and came third in the up to 2000cc Modified class
at the Brighton Speed Trials - still in roadgoing trim. Over the
past few seasons the car had been used less and less on the road
and during the winter was converted into a full racing specification.
