received from Stephen Mell in August 2008 with some photos of his
Caterham 7:
Potted history:
I first acquired my Caterham in 1999 in its 2.0L fuel injected guise.
It quickly became apparent that this was a bit of an asthmatic beast
that needed liberating. So started my 'power' quest with SBD.
Step 1 was their TB208 kit which involved the fitting of
Jenvey 48mm tapered throttle bodies, an MBE ECU & loom, ARP
rod bolts and mildly uprated cams. The transformation was awesome,
it felt like someone had unhooked my braces from the lamp post!
Step 2 was the TB225 kit that provided new cams, solid lifters
and titanium valve caps. This was then coupled with the SBD 4:2:1
matched length exhaust system. Whilst not as drastic as the original
upgrade, this added power and torque that was still tractable. |

Step
3 was the TB235+ kit, which again provided new cams and this time
a full dry sump system was added.
The final step was to go for the TB270+ cams, 87.5mm (2.07L)
pistons, 12.4:1 CR and a pretty agressive map. The result is a rip snorting
beast that remains tractable in traffic yet sufficient to frighten the
bejezus out of me on the track.
Thanks to Steve, Dick and Carol at SBD.
