Has anyone had any experience with using an aluminum flywheel on the street? I'm familiar with their use on oval-track cars and the benefits derived from one (feels like adding 15-20 hp on a 2300 4-cyl. from quicker rpm gain) They're not cheap, but are available for small-block Fords and I'm wondering what "down sides" there might be...aside from cost. Anybody??

Main negative is lack of intertia when operating with low compression and moderate cam lobe overlap. More of a driveability than performance issue. High numerical rear gears would mitigate substantially.

Personally, I wouldn't run one on the street.

Track engines are a completely different animal. Even then, we never ran aluminum flywheels on small blocks (drag racing) but I do understand their benefits to oval/road engines, especially on tight courses.

I concur w/Pat. My stang has a "Factory" one installed (actually came from shelby's shop that way), and with the tall gears & high torque, it's not a problem. But if I were running say 3.50's, it would be a very difficult street driver.
