Cool, I'm sure I can make it along to one of them. Prescott looks promising, it's only about 60miles up the road.

It's also one of the better Hillclimbs for spectating.
I'll be there (silver & black SS1), come and say hi

Cheers, Raz

ok sorry to bump old thread, but season is now nearly over (just Castle combe left on oct 20th) and i realise that i never put up power figs even though a few asked.
spec is as can be seen in the earlier pics, basically forgies, steel rods, lightened + balanced everything, autosprint cam, CNH Diy headwork, cut'n'shut DET tubular manifold with external wastegate and turbo technics T28 hybrid.
engine made 282bhp and 266lb/ft at 15psi boost

have the printout from Dave Walkers Emerald dyno (PPC mag tech guy) somewhere if anyones interested.

impressive figures Craig, similar to what I'm going to try to hit but with a few different methods. have you got any idea of the spec of the autosprint cam? I'm chatting to them at the moment

CNHSS1 · #90 30-09-2007, 14:33

not idea on specs really. i took geoff (Mr Autosprint) a Piper one and he based his 'special' on that. it has an asymetric profile ans the one side of the cam lobe is flat. a trick from some of his ford cams apparently. works great tho, breathes much better at high revs but then so does the piper.
