Following the guidelines from the 750 bulletins of the '50's and '60's, we took 2.5 lbs off the flywheel and pressure plate combinations of our single seaters and they now rev to 6000 with ease.
For a road car you need a bit of reciprocating mass to carry you up an incline, when it comes to shaving rotating mass, it's a fine line and on a road car I'll suggest that less is more and you would gain by lightening the flywheel say 1.5 lbs and balancing everything really well. Effective balancing + reducing reciprocating weight will benefit from careful assembly to minimize friction and its associated losses will pay dividends in the end.
Take off too much and the throttle pedal then becomes an on-off switch.... A hair-fine trigger racing motor in a regular driver is not a pleasant traffic experience.
My 2 pence worth
