has anyone used a alloy flywheel on the street i am thinking of running the one i have but i am not sure if it would be ok

Dean,
What engine are you running? The guys I know with a modified grey all use a standard weight flywheel as a light flywheel reduces torque in a grey dramatically. I currently have a light flywheel in mine, but will be reverting to a full weight wheel after Jindabyne. My car has got bugger all at low revs.

I would suggest that an alloy flywheel would make the car more difficult to get off the line.
I had a torrie with a warm 173 and aussie 4 speed, when I had the gearbox rebuilt ;D I had the flywheel lightened. It was harder to get off the line but with less mass in the flywheel to spin it got up the revs a bit quicker.
If the alloy weighs less than a lightened steel flywheel, I'd be steering clear\.
Alloy or lightweight flywheels are useful in high power/high rev situations where torque isn't a priority. Basically big cam, big port engines where you are looking for maximum piston speed in the shortest amount of time.
As Colt and Stinky have indicated they reduce rotating mass allowing revs to rise more quickly. OK on the street if you live in a flat area and don't tow a trailer :-)
Cheers,
Craig
Thanx guys
I am currently rebuilding a 3.3 ltr to put into my van i bought the motor ex speedway and it came with a lot of spare i am just trying to figure out the best set up for me. i am also running toyota 5 spd and 3.36 diff
