BSFC for a racing twincam -

[cabc26b]

Does anybody have a BSFC number for lotus twincam racing engine ? I have been using a ball park number on some calculations I am running, I want to make sure I am in the ball park.

Common now, one of you more theoretical guys have to have this figure .......

Thanks,

George

Hi George

I am not sure that these will help but these are the dyno sheets and graphs of the two twin cams that Kenny Duclos built up for street use that I own. One is in the brooklands green S2 Elan and the other is sitting in the white S4 coupe in the back room that you looked at when you were up here. Both are 1700 cc twin Cams despite the information printed on the sheets. The white paper is the white Coupe and the pink paper is the Brooklands green S2. Neither are race motors but are warmed up street engines.
