Lightened flywheel

[Jon_nova1]

I can get my flywheel lightened for free, but the person thats doing it wants to know how much to take off, how much should be taken of to get decent BHP gains but not have it stupidly bad its not drivable on the roads?? what kind of difference would different weight losses make?

lighter flywheels dont physically add on horse power they just make less stress on the engine. there is less force needed to turn the flywheel so therefore using less power. also making it lighter makes it easier to rev due to the reduced centrifugal force applied on the flywheel.
i cant remember how much mine was lightinged by, phone a company called GOSNAYs in Romford/Ilford and ask them to quote you a price for lightning and balance your flywheel and how much they would remove to keep it safe.

I know about it not adding horsepower, you just get better aceleration but the top end speed will stay the same, its a 5KG one from a small block nova i've been told for road use don't go under 4 KG, i don't need a company to do it i can get it done for free, i doubt the company would come up with an ideal answer, i imagine id get told about different dependancies etc

imho id simply have it balanced up with the rest of the bottom end... small blocks dont tend to ahve much torque anyway so its best to keep a bit of inertia there to maintain torque when going up slight hills etc lol Ive not bothered getting mine lightened for the silly 1200 and tahts set to rev to 8-9K

My old E16SE had a lightened flywheel but it had 120 lb/ft torque so it loved it! I'm not sure how much they skimmed off it tho'

its a 1.6 beating 1.4 lol and if i got a flywheel lying around and can have it done for free why not :D
