Advantages in steel -vs- aluminum flywheels?? I heard that the aluminum flywheels will help you rev faster, and dyno higher, but for a drag racing application, a steel flywheel was better. Any truth to this, anything else to add? Thanks, Shawn

Re: Advantages in steel -vs- aluminum flywheels?? Hey Shawn,
My aluminum flywheel ( Hays, 15lbs) made the car rev much faster and was worth a few HP. I LOVED it on the street. However it sucked at the track. <img border="0" title="" alt="[Sad]" src="gr_sad.gif" /> The car was so hard to lauch consistently. It would either bog or spin, very fine median between the 2. It would also fall on its face if you let off the throttle slightly, killing your initial momentum. If drag racing is your thing, I would not recommend it.
I now have a heavier steel flywheel and it is much better. Also note that some steel flywheels are lighter, like SLP claims theirs is ~16lbs I think. So consider the comparison weight of the flywheel more so then the material. I think if our cars were lighter then a lighter flywhel would be OK, but a 15lb fw doesn't cut it for a 3600lb vehical.
