Alum flywheel vs Steel flywheel debate let's hear it
I used to have a steel which was great on the launches but trying to save my tranny I went with a alum flywheel. I know in drag racing you need enrtia(sp?) but heres my question:
If your able to get the car to 60ft the same then the alum flywheel will allow the rpms to climb faster due to less rotating mass right? But if you shift slow then the rpms drop faster. Let me know your thoughts between the two FW. Thanks. -Mark

The big thing is IF you can get it to launch the same. My car and every other WRX I've seen with a lightened flywheel has fallen on its face when trying to launch. With no wheel spin to get rid of some of the energy produced in the drivetrain and loss of rotating mass from the lighter flywheel it just bogs bad off the mine. That's something you might want to think about before doing it, I'm going to be pulling mine out soon and going back to the stock flywheel.

I would only use an alum. flywheel in a high rpm combination (like my old S/B combo). Those types of combinations are all about lightweight components (rotating mass, valvetrain, trans/gears, etc) and they're geared up enough that getting the car to 60' isn't an issue. JUst my $.02 though.

Also works great with a blower combo due to allowing the motor to rev faster which brings in boost faster. 60 ft may or may not suffer depending on torque output and launch rpm.

Do you own a Torch Red FRC and tremble every time you drive under I75 on Hwy 60 and look in your rearview mirror? If so you are suffering from what is known as Cobraphobia.

I'm thinking that my first time out with the alum FW my et was so off cause I was over reving the car. I hit the limiter on the 1/2 and 2/3 shift. The tach used to be off alittle. I would shift at 7k and not hit the limiter. Now that tach is right on the money. Everytime I got the needle 1 pubic hair above 7k I tapped the limiter. I think I'll try 6800 and see what happens. -Mark

Aluminum flywheels are 2 peices, the ring gear breaks off when the center is too hot. If you go with aluminum its not gonna be a daily driver. Also you should loss torque. Torque = rotating mass.
