Flywheel opinion

[untouchablecc]

I currently have a Fidanza flywheel. Its not a bad piece but i wanted to know if you guys think i should put a stocker back on, which i dont have. The reason i would consider this is because this is for a street strip use an understand inertia will cause a sooner spool with a heavier fw. But i just wanted to confirm this an have some opinions. I think a act street light might be a bit better because its 13 lbs instead of 8 like a fidanza an i really dunno how durable a stocker is so this is why im asking. I dont really have the money for a street light so keep that into consideration.

Thanks memebers.

A heavier flywheel will make your engine rev slower which will cause a slower spool. A heavier flywheel is for momentum for launching, useful if you have a heavy car. AWD cars should stick to the stock flywheel because you need the momentum to get all four tires moving.

Stick with the fidanza. I love mine.

I have no problem free reving with my act streetlight flywheel and cutting 60 foots 1.8 or lower. I agree you want some weight for awd. 2step and stuff helps also to get some psi off the line.

I agree with an ACT flywheel. It's like a happy weight medium between the heavy stocker and the light Fidanza. The stocker has a tendency to break parts quicker than the others because of the increased inertia.

I`ve run both a Fidanza & an Act. strretlite - and really to be honest, They both seem to perform the same, both very good . . .

yeah I personally cant see those few extra pounds making a difference. Maybe Im crazy but I cant tell a diff between my fidanza and my stock flywheel. Free rev is a little quicker but other than that....thats it.

Alright thanks alot for all your help guys, its been needed.

It's all physics and rotation inertia, a couple of lbs is a large percentage off the stock flywheel.

Of course.

a couple of lbs is a large percentage off the stock flywheel.

And this may be the case, but like I said, under my own experience I didnt realize any noticeable performance increase.

The rotational masses is significantly less which makes it capable of revving faster at throttle.

It really depends on your drive style to see performance. It works best for autocrossing where you upshifting and downshifting working those RPM's whereas you probably won't notice much for drag racing.

i don't know about the 2G people but the stock galant flywheel is 15 lbs. galant and 2G FWD flywheels are identical unless yours are heavier.

the lighter flywheel gives noticibly quicker reving ability but it also falls quicker too. daily driving can be a pain in the dick on hills(it bogs down).

that being said i had my 8 lb fidanza fail horibly. the fidanza is actually 2 pieces. the aluminum flywheel and a steel starter ring held in by 3 tiny bolts. my starter ring came off the flywheel and jammed against the block while driving. the bolts that came loose tore the back of the flywheel up. i currently have sent it back to fidanza to figure out why it failed.

check to make sure all is good with your fidanzas to avaoid this problem.

this is the bolt that went missing

Having a stock ECU could partake in the bog down or is maybe your ISC.

Load increases spool. This is why 4th gear spools a little faster than 3rd gear. And this is also why a heavier car like a GVR4 spools a turbo faster than in a T/E/L. The heavier weight provides load. This would cause a turbo to spool faster.

With that said, I've noticed zero difference going from a stock 22lb fw to the 13lb act fw.
