Interpro dyno graph - sorry about the quality BUT Interpro really need to get hold of a good up-to-date printer, the one they use is like the type only available in the late 70's

Notes:
Boost is capped to 24 - 28 PSI up to 6,500 RPM...This is to prevent the surge that only MAD engines dont suffer........Maybe Mark will tell us some of his secret specs one day .....

I told Dave Griffiths (RR opperator) that he must rev the engine past 6,500 and right up to the 7,800 RPM soft cut limiter with at least 80% throtle, otherwise the the mapped in 32 PSI high boost would not kick in..........He "thought" I said "rev it to 6,800"
