boost and alunimun flywheel
Sunday, April 28, 2013 9:42 AM
I bought a aluminum flywheel to put on my turbo 2.3 quad4 I built for my chevy beretta gtz and I am ready to put the motor in but someone told that it would be a bad idea to use a aluminum flywheel on a turbocharged motor. Have any of you guys used a aluminum flywheel and had it fail and what should I use? aluminum or steel flywheel!

by the way my clutch is a stage 4+ and my goal is around 600hp.

Ecotec here but I have a twin disc clutch with aluminum flywheel. All that is different is that it revs and rev drops faster.

^^ and it accelerates the car quicker. if you know how to shift the dropping in revs shouldnt really affect it.

with as heavy as a quad 4's rotating assembly is i would definitely go for it.



M45/OS crank/2.4 snout. It's nice to be injected but I love being blown!

After seeing the nightmare that many have gone through with Aluminum flywheels on this platform I opted to go with a lightened stock unit. Was shaved from 18 lbs down to 11lbs. Not quite as light as the aluminum units but I have peace of mind.

Slowly but surely may some day win this race...

All the Fidanza and spec units that failed were from the first design. The second design is MUCH thicker.
