Ernie ... correct on the flywheel . I had a friend who was a serious squirt racer . They had a computer program that would figure the optimum flywheel weight when a whole bunch of parameters were fed in . But to summarize ... and be VERY general ... heavy car , heavy flywheel , light car , light(er) flywheel . You ought to see the flywheel on my Galaxie ( 4100 lbs ) .
A heavy FW helps you come off the line as the engine doesn`t bog down . In circle track racing , some of the big teams ran a Ram clutch setup ... it had little or no flywheel ... talk about instant acceleration and deceleration .
I machined all the counterweights off one of my cranks once and machined my flywheel to look like Swiss cheese ... boy did it rev quickly ... boy did it destroy main bearings !
