Re: Spaceframe Imps

Exploded a BDG? Ouch!

It was the cost of exploding a proper 1975cc BDG that put an end to George Bevan's two litre Stiletto programme with Rob Mason at the wheel in 1977.

A new block then cost about £1700, a crank £600. God only knows what a good BDG costs these days.

Fred Hendy used either one of two 850cc motors, one of which was a bitsa of the standard 68.0 x 58.0 format, and the other was a semi-short stroke motor with a 69.5 bore using stock one litre valve sizes. This engine, which I loaned to Fred, went lik...

Re: Spaceframe Imps

With regard to the question of wings and spoilers, British Special Saloon regulations did not allow the use of aerofoil rear wings in the three smaller-engined classes (up to 850cc, up to 1000cc, and up to 1300 cc). As Doc Knutsen hints at, David Enderby's Chamois Coupe had two different aerodynamic...

Re: Spaceframe Imps

Ignore the tailpipe; you're meant to copy it up to the two-into-one collector only! From then on, it's a straight pipe, unless you raise the engine and have to put an offset into the tailpipe to clear the rear body crossmember.

Before his Group 2 days, George Bevan (who loved old motorcycles) did indeed try using four separate pipes with megaphone exhausts on his club car. He told me it sounded great, but didn't work.
