I've heard so many different opinions and really I don't know what to think. None. The revs will come quicker. 150 I believe. nx2000racer 03-16-2003, 09:50 AM hence making the car faster??? i will never understand this... if you buy LIGHTER pullies for the left side of your engine, and it gives you HP, how come a LIGHTER flywheel on the right side doesn't??? nikko 03-16-2003, 01:56 PM The engine will rev faster. However, as a side effect your engine will also make marginally more power in the first 2 (maybe 3) gears due to smaller rotational inertia of the flywheel. In higher gears you might actually loose a couple of horsepower due to a lighter flywheel. sr20ser 03-16-2003, 02:52 PM nx2000racer, The pullies are actually smaller in diameter, thus slowing your accessories down and gaining HP. -Tim honkeybizkit 03-16-2003, 04:35 PM Originally posted by sr20ser nx2000racer, The pullies are actually smaller in diameter, thus slowing your accessories down and gaining HP. -Tim the majority of hp gained by lighter and underdriven pulleys is the loss of weight, not the underdriving.... read up on unorthodox pulleys, they have some info on their faq, i believe. nx2000racer 03-16-2003, 09:21 PM yea, thats why ive always wondered why theres no # given to a flywheel... interesting... kesi24 03-17-2003, 08:16 AM Iv been telling people flywheel gives HP. Just look at www.nissanperformancemag.com they dyno a se-r w jimwolf flywheel.....kesi24 | ||
