i like mine....minus the strange rattling sound it makes when the rpms are coming down...and its NOT fun driving with the a/c on with it...by which i mean trying to get it going from a stop, it loses momentum too quickly...of course i dont use my a/c....roof vent FTW!

Depending on how lightweight of a flywheel you are talking about. I've been told that you shouldn't go below 13.5lbs or else you'll have to rev the hell out of it to actually move. I have a 12.9lb one with a ceramic clutch and at the strip I have to launch at 5500 to 6000 rpms to get a decent launch. The plus side of this is that the car is able to rev up alot faster IMHO, combine that with a lightweight crank pulley and you'll really notice the difference.
thnx crazy taxi i was gonna ask about the lightweight crank pulley. so with the combination of the two does it really make a big BIG difference?? n do u have the pulley system too?? what are the bads of both?? cuzz i can remember hearing negative comments about both but not where or why it was probably just some bullshit a while ago beefore i knew anything
What are you looking to get out of it? Read the link provided. Like mentioned above, the car revs quicker, but at that same time, this thing called inertia is in effect. Having less mass means they dont spin as long when you dont apply "power" the stop spinning sooner than the stock set. This also translates into it being a little more tricky at low speeds and even pulling out in a manual car.

ya of course it's manual. i was hoping to get some HP out of it n a quicker rev wit faster take off. is that what i'll be getting out of the combo?? so the only downside is that when the pedal is released the car will slow down quicker??
Im not a mind reader, I have seen my fair share of automatic WRXs. I dont really know if you will get more HP, but yes the revs will build quicker and at the same time fall faster when the pedal is released.

I've only got the lightweight crank pulley and the lightweight flywheel. Yeah, it makes a noticable difference. Under a load, it will rev faster, much faster when you're in boost.
As newtothegame said, it does slow down faster when you let off. I don't find that to be a bad thing, especially with running a rather loud exhaust. Cops tend to frown on that kind of volume unless it's a Harley. (Still don't understand that.) Only problem I've found is that I tend to bounce it off the rev limiter when I'm going from 1st to 2nd and 2nd to 3rd at the track. That cost me .3 seconds. Oh, and I'm not getting as good of gas mileage. Again, inertia has alot to do with that I'm thinking.
Only thing I can recommend is to stay away from underdrive pulleys. If you want to do a pulley set, go with the lightweight OEM size pulleys. That way you can keep the stock length belts and you don't over-drive your accessories. Doing that will decrease the lifespan of the various items. Power steering pumps and A/C compressors aren't cheap.
aright cool sounds good man ya i really don't have a problem wit it slowing down faster at all but the gas mileage definately caught my attention. i would expect it to not change at all if so atleast very minimal give u maybe a mile or two because of the weight?? do u think it's only from having higher RPMs more often??
You don't hit higher rpms more often persay it takes more rpms to get the car going from a stop.You will hit rpms quicker once moving.I have to rev up almost 1000roms more to get the car to leave normaly from a dead stop or the car will bog.I'm running the ACT 14LB Streetlite.

i have the act prolite flywheel on mine and i do have to give it a little bit more gas to get going but once you get it down its not hard to drive. it does rev alot faster tho. the first time i ran it through the gears, it reved so fast in first i messed up my 1-2 shift. i've heard that its harder to launch at the strip and it slows you down but i really don't see it. my fastest time (in september or october last year) was a 13.2 with 2.0 60'. i went when it was hitting about 80 degrees and ran 14.1 with a 2.2 60'. thats a second slower with a slower launch and higher heat. im going to go back soon to see what i run in colder conditions and more experience with the flywheel. also, i think its worth noting that i am running a stock clutch with 350 hp...it feels like thats keeping me out of the 1.9 and down 60'.
