Steve, BMEP is brake mean effective pressure, the pressure in the cylinder at that point in time.....
Geoff, I don't know, it was a Rootes Group rally engine prepared for a local dealer I got for a spare....I did not race this engine...the engine I used was tuned by Greetham engineering for power boat racing and was supposed to have 118BHP....it had nothing below 6k and pulled very strongly to 10k, but 9.5k was safer....they were as quick as the first of the Yams, revs came up quicker in the Yam though.....
