Mech - interesting read. I've looked at the between-war and postwar racing engines quite a bit. Always been impressed with the high outputs and low sizes of some of those supercharged engines and more impressed they survived being lubricated by the poor oils of the time. One question, wouldn't smaller valves encourage more pumping losses instead ?

The stock block requirement was dropped for 94 which allowed Ilmore to exploit the loophole and make a specific race engine.

The FE thing is confusing. My 1.9 TDi makes less FE with 130 HP in a small hatchback than my wife's 2.0 TDi (with 16v mind) does in a Jetta sized estate.

Time to look more at that nut behind the wheel again I suppose.
