Is the aluminium flywheel you have josh sfi approved and are they typically stronger than the stock iron piece? I've been wanting a sfi flhywheel for the turbo motor semi worried of taking my toes out with the new found power.

| Post subject: | Aluminum flywheel... |
I remember seeing the aluminum flywheel subject get thrown around over here a while back...and I DID search but found nothing. Maybe I wasn't holdin my mouth right. did anything ever come of it? Is anyone making an aluminum flywheel that's a direct bolt on? Thanks. |

Wilcap makes one. I have one with the '68+ large center register I'd part with if you're interested. |

Less mass allows the engine to rev quicker as the flywheel is storing/absorbing less energy. Generally makes it a little more difficult to get off the line smoothly especially if low gear isn't low enough. Light flywheels are best in light vehicles with ample power and/or good gearing. |

Also, since a light flywheel stores less energy, you will have to increase idle speed some and/or deal with a "rougher" idle compared to the same eng with an iron flywheel. That's why many old engines (flathead straight 8's) idled so smoooth- they had big HEAVY flywheels. Again, that's a plus in launching a big heavy car. An aluminum flywheel would be great on a stripper A-body with a turbo 170 & steep gears. |

I put an aluminum flywheel in my '65 Coronet street car last time I had the engine out. Of course, it is a 512 inch stroker big-block so it has plenty of torque. |

I have been running one in the '64 Dart for the last 5 yrs. Big cammed engine, so idle is a bit rough anyway. Might be a bit twitchier when letting the clutch out, but I am fine with it. Lou |

How much weight is saved using aluminum? Do you think it would help in the 1/4 mile? Or is it more beneficial for road racing? I was thinking about it for my dart. |

It about an 18-20 lb weight savings over most passenger car flywheels. It makes a big difference in how the car accelerates in the lower gears. It's not always the best for drag racing though as a light flywheel doesn't store as much energy to help launch the car. |

Yep, a little harder to launch, but I saw no real difference on the dragstrip. Car revs easier in neutral and should wind up a little quicker on the road course, but hard to tell by seat of the pants. Al flywheel is 11-12 lbs and a stock iron flywheel is 20-22 lbs, so you save about 10 lbs. V8 (or 11" clutch) flys are about 30 lbs, so bigger savings there. Lou |

This flywheel isn't SFI approved per-se, but it's billet and I believe would pass certification easily if tested. It is much stronger than a cast flywheel. I would contact Wilcap and see what they say about it if you need the SFI sticker. I was going to use this on a high RPM 170 as SCTA/BNI says no cast (Fe or Al) flywheels, but lucked into a billet flywheel with a small center register. |
