i haven't gotten mine put in yet...but you should rev faster....accelerate faster....and you should feel the difference don't know if that equates to more whp but....its worth putting in, in my book...

It doesn't.

i agree with what knalige says 
I noticed a difference from a rev faster accelerate faster stand point.

like said before, you don't gain whp but you can get into your sweet spot quicker with the lighter flywheel, but remeber that you can also drop out of it quicker because you have less rotational inertia(sp?) and thus more RPM's are lost during shifts...let me know how you like this mod..i been thinkin about doing it with a 4.9 fd

Wrong, the amount of revs dropped during the shifts is based on the gearing itself, but the engine will slow down faster with a lighter flywheel.

Re: (El Pollo Diablo)
i did notice that too
it seemed like the rpm needle would linger a bit more before it started to drop.
on my 2000lb flywheel it would just drop :B
-aoib0t, who loves the change on his car more importantly, he's glad the clutch was changed because it was "broken"

It should be the other way around, Aoi.

are quarter mile times increased with the fw installation...i assume so.. anyone experience a time difference?? what are ypor times..

I just installed my ACT 8.8 and it feels pretty dam good. I'm still breaking the clutch in, but match-revs are hell of alot easier (and quicker). Good investment IMO

When you downshift, you blip the throttle before selecting the next lower gear to make the engines speed meet the transmssion speed. It helps make the transition smoother.

not sure what j00 trying to say aoi...
engine will slow down regardless of stock or light FW, if j00 let off the gas.
If the engine slows down, the rpm also slows down.

Re: (AoiGSR)
although a lighter flywheel will not affect crank horsepower shouldn't it theoretically improve wheel horsepower since there will be less energy required to spin the flywheel?

Yes, there will be less energy spent spinning the lighter flywheel up. So it doesn't MAKE any horsepower, but frees some up...
Although it will seem to do just that when dynoed on an inertia dyno like a dynojet.

Re: (El Pollo Diablo)
If you were on a more classic Inertia Dyno from the 80's, a flywheel will show an increase in power...but even a change in tire pressure can ammount to a change in power on an inertia dyno.
I love my Fidanza 7.5lb peice. It definately helps out at the track during heel-toe, where you dont have to 'stab' the throttle as much as just 'blipping' it.
As for any negative sides to it, well, if you have a problem with working your clutch foot just a bit more on starts, then you may want to think twice about going really light. Other than that, normal shifts become smoother because theres less inertia for the clutch to grab to. And I've never had a problem with revvs falling too fast between shifts, but then again, I still have AC and PS.

My $0.02.
In daily driving, you're going to find it (at first) a little more difficult to drive smoothly and might find yourself wanting to shift quicker in order to avoid RPM drop b/w the shifts (when the clutch pedal is pressed in).
