How many sheets of paper would you allow if you were the scrutineer before deeming the motor illegal? It is a funny thing in motor sport or the motor sport I have been racing in for too many years, they write the regs for a reason with a hard limit on stuff like this so people will not fudge the limits. Give an engine builder a tolerance and he will push all the way to the tolerance prescribed in the regs so there may as well be a hard limit with no tolerance. Engine builders are there to derive as much HP as they can and if that means cheating they will and will deny it with a straight face. Been there and done that.
So the question remains, how far over the limit on lift can a motor be before it is deemed illegal? Two sheets of paper, or three or maybe five, I seek your wise answer.
