Flywheel

[stubbs_GS-T]

I am about to change my stock flywheel to a light weight racing flywheel. Does anyone have any thoughts on this? Does anyone have any expirence with this type of upgrade? If so, what should I expect?

Thanks


Stubbs out,

You should get to redline a lot quicker =) Also, just consider getting your current flywheel resurfaced, it's almost as good and a lot cheaper.

So, getting a flywheel that is not as heavy as the stock one is better? Will it increase my HP/torque?

It might increase your power slightly, but notice that nobody mentions this as a mod until you have 500whp.

i got my stock FW lightened when i got a new clutch and i didn't notice anything diferent, aside from the chatter of my current clutch [same one]...

A lighter flywheel can not increase power or torque. It can allow more to get to the wheels though, since less is wasted in trying to accelerate the mass of the heavier stock flywheel. Most people never see a difference in thier timeslips or on the dyno though. Its a good mod for road racers and autocrossers, since it makes revmatching and such easier to do. You get quicker revs, but only when the clutch is in. When the motor is attached to the wheels, a couple pounds off the flywheel doesnt mean a whole lot. Common misconsception though, since it revs more freely in nuetral.

I personally dont think its worth it, unless one of these scenarios applies to you.

- You need a SFI certified flywheel to pass inspection at your local track for the times you run
- you road race or autox and it will help in downshifting, etc
- You burn clutches up quickly and a replaceable surface is easier than getting it cut everytime you change the clutch.

I'm getting one for reasons 1 and 3

Its also worth noting that there are two basic types, chromoly like Jun and ACT. Some think there are heat related issues with them (cracking) but I havent heard any bad reports on the ACT version (and its SFI approved). The other type is aluminum with replaceable friction surface. Lightened stock flywheels have become somewhat famous for exploding and totaling the car. There are two interesting vidoes out there of this in action I dont trust them.

you also have to balance the replacable ones too...
