i want to get ur guys opinions on this, i am thinking about gettin a LW aluminum flywheel for my car that will be turbo’d and i heard that there is a good chance that if u run a aluminum flywheel with a turbo u could warp the flywheel cause of the heat. so does anyone run one with a turbo or have any experience? ---

I don’t really think a turbo is going to make the transmission hotter… ---

i’m taking out my 9lb flywheel and going back to stock cause it’ll rev too fast once the boost hits… if you have a moderately sized turbo tho i woudln’t worry about it ---

engaging is in the clutch… the lightweight flywheel has less rotating mass so it will rev faster ---

Alum flywheels are pretty much MADE FOR RACING apps. they sure arent OEM replacements. I think You’ll be fine with any ‘extra heat’ will they create a lesser load on the motor thereby delaying boost? probably… a hair or two. Will it rev quicker to ‘mask’ or compensate for this? probably. Eitherway, less rotating mass is usually not a bad thing at all. Consider going to a puck clutch as well. $0.02 ---

Big turbo + LW FW + big cams = bitch to launch and bog then no traction when boost hits. ---

Are you upgrading the axles? if not… are stock saturn axles going to holdup, against hard launches? ---

> [@Twizted](#): > > engaging is in the clutch… > > the lightweight flywheel has less rotating mass so it will rev faster yea i know its in the clutch but i meant the heat it creates from the friction and some slipping. the car i have i know most of u wont know about its a saturn cause i know how popular saturns are lol. but yea i will have a 6 puck clutch in the car though too > [@beckington](#): > > Are you upgrading the axles? > > if not… > > are stock saturn axles going to holdup, against hard launches? no im not goin to upgrade they have held up to 400+whp so far and im not goin to be near that for a while plus they would be a one off thing and i dont have money for that ---

because your car cant use the larger rotational mass of hte flywheel to keep the motor going… so u basically wont move at idle speed around a lot, ull always be slipping the clutch ---
