do you think this would free up some power on a stock 94 GTS? Does anyone have this flywheel?

it's 4.54kg (10lbs)

It would get you a lil more power to the wheels.

A lightweight flywheel actually doesn't give you any more horsepower. It simply reduces the rotating mass, which allows everything to rotate a little bit more quickly, meaning your RPMs will climb faster, and your car will therefore be faster.

Moved to a more appropriate forum.

Sorry. my bad, thanks for moving it

so do you think you would notice the flywheel difference with little or no mods, and the stock clutch?

you'll notice that you can rev ur car faster. The rpms will go up and down alot faster. But ur not gonig to notice a helluva lot.

how does it affect other aspects of the engine and performance..

I have a centerforce dual friction cluth and a clutch masters lightened flywheel, honestly i didnt notice a large different in the rpm revs when i first got it but i did notice faster acceleration. i payed about 500 dollars for the flywheel and i would do it again, it depends on if it is worth it to you.

If you plan on modding your car, do your clutch while you're doing the flywheel. It'll save you time and money. You might also wanna get the clutch and flywheel balance while you're at it. Even a new clutch and fly wheel will need to be balanced

Clutch and Flywheel, which ones to use...how much would they cost+labor..
Has nybody done it...
mark920, how much did it cost you to install...are there any figures on how quick ur car got.
Thanks,
Preetham.

I got a Clutch Masters stage one kit for an AE86 Corolla GT-S for my car, and a JUN chromoly steel 9 lb. flywheel for an AE86 Corolla GT-S as well, and installation was free since everything was already apart anyway.

Unfortunately, I won't be able to compare it to anything, because I'll never have driven my car with the 20 valve 4A-GE and a stock flywheel, but it should be fun. Hopefully it'll be done by the end of the weekend.

Oh yeah, I talked to Neipas shortly after he got his stage one clutch and lightweight flywheel and underdrive pulley, and he said that his ST was much faster than before.

Coomers a little bit off but on the right track. The engine won't actually be making any more power, but you will see slightly more power at the wheels from reducing the rotating mass. I would think it should be noticible considering your cutting the flywheel mass at least in half, if not more. I can feel the difference switching from a set of wheels/tires that weigh 38lbs a piece to a set that weigh 43lbs a piece.

Thanks for the correction. I thought I read somewhere that if you dyno a car with the OEM flywheel and with one that weighs half as much, you'll get the same results, but the one with the lighter flywheel will win in the 1/4 mile.

Nope, I've seen it first hand. It all goes back to the definitions of power and torque. A dyno actually measures torque. Torque is how much work an engine can do (for instance it can create 300lb of force at a radius of 1ft for the center of rotation = 300lb-ft, notice its not time dependent). Power is calculated from torque in the dyno software. Power is the speed at which the engine is able to do the work. RPM now enters into the equation. Since the rotating parts are lighter, the engine revs faster. Its not making any more power within the engine, but the lighter parts 'freed' up some of that power and thats what the dyno sees.

Gotcha. Thanks for clearing that up.
