Simon Braithwaite - Caterham 7
 
The 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 direction.
Retaining 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.

The 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.
