Aluminum flywheel vs Steel and Clutch ? - Page 2

Hind sight being 20-20 I wish I had Kieth supply dyno #s below 4500 rpm just to see what the bottom end looked like. I opted for the .82 OD since there were a lot of people complaining about how sluggish the .64 made the acceleration.

Since I'm running the fuel injection, it's probably less of an issue than if I was running a carb.

Ideally the .64 would be a great 6th gear...

BTW don't forget about changing your input shaft if your going with an FE..

Just stick her on a chassis dyno. Keith runs his dyno numbers without anything on the exhaust (as do a lot of builders). Dyno numbers for an engine sitting on a dyno with no mufflers/sidepipes (and maybe no water pump, etc.) can be very misleading.

I have the Fidanza flywheel on my 482. My feeling was that with 605 ft/lbs, I should be able to get the thing moving in first without too much trouble. I was/am trying to keep the total weight under 2350 which I think I have done. I have not driven the car yet, but in just checking the clutch release, it seems fine. As soon as the snow is gone (maybe July at this rate!) I'll find out.

That will be interesting. Please let us know how if feels.

I have the Centerforce #900260 aluminum flywheel on my 428FE. Why, you ask, do I have the zero balanced 427 version on my 428? Because with the SCAT stroker crank you internally balance the assembly. The flywheel weighs just over 17lbs and works just fine for me -- I wouldn't change it. I have no idea why Centerforce wants $750 for it -- maybe it's the beautiful gold inlay

. The competitors are charging half that for theirs.

I don't remember it costing that much three or four years ago. And I don't have a good reason for spending the extra money on Centerforce if it did.
