I know the basic physics behind this issue but still a dyno graph would show the changes in curves despite the overall horsepower or torque were the same. And, when claiming somenthing has changed in performance, you should have some facts. At least my arse-dyno is not that accurate and reliable that I could say something has changed/imprroved just by the feel

some dynos measure at a rising rate - I suspect it'd be noticeable there.

I've just ordered an aluminium flywheel for the Holden, so I could do a "before and after" timing check - I have a GPS dete logger, so it'd be reasonably accurate.

I have an old Race Technology AP22 accelerometer if you want to borrow it? A bit of work to do before I'll need it, I suspect.

And you can download RaceChrono to your mobile phone (you'll need a GPS signal, so a phone with GPS or a separate bluetooth GPS is required) http://www.racechrono.com/

Don't know much about car flywheels..but in the off road motorcycle world people who want to run "revvy" motocross bikes in enduro events that often (at times) require lower speeds and more engine tractability than a flat out MX race nearly always fit a heavy flywheel (stator) in the engine to "soften" the power delivery at low revs.So the opposite is what is being dicussed here I guess ?? :-?
