If you go too light it kills the inertia of the flywheel. A lightened flywheel is great if you maintain high revs constantly, but it will also drop rpm too fast if you are driving at low rpms. A heavier will build inertia quicker, but the added weight the engine will struggle at higher rpms. So realistically for the street you want to find a good balance between the two.

 

I went with the act prolite and have had no issues with mine. I think its 8 lbs just be on the gas after shifting. I do think a lighter flywheel will cause more clutch buzz with some clutches but I never had any with my act street disc.

 

IMHO, the lighter flywheel makes the car more fun to drive. I do tend to stall it once in a while......very race car like.

I'm running a Comptech flywheel at about 8-1/2 lbs on my supercharged AP-1. Dramatic difference from the AP-1 flywheel at 14 lbs.

 

Ok, thanks for the help guys!!

 

ap1 oem flywheel here. feels way better then the stock ap2 wheel. no ill effects, car runs and drives way better.

 

I agree. I prefer lighter. I have run the 14lb ap1 on my f22 and it’s an improvement, feels proper like what the f22 SHOULD have came with, but I currently have the Act pro light on these days. 8.3lb. it’s a really fine quality piece of machining. Love the way the motor response with it. Will never go back.

 

Does anyone know where I can grab a resurfaced and good AP1 flywheel for cheap?

 

Id just buy an AP1 flywheel and get it resurfaced at a local machine shop.

 

for sale section. i bought one and brought to local trans place and had them resurface. i think all said and done i paid 80-90 bucks.

 

gtmotoring sells competition clutch flywheels, they have 2 the lighweight and the ultralightweight one, and those are not that expensive
