Holds 370whp 340wtq flawlessly (awd mustang dyno)
I paired this flywheel with the act heavy duty street performance clutch. As title says this clutch/flywheel is awesome! Put a total of 700 miles on it before hitting an autocross track. Started with 250 easy driven miles, after that a few pulls here and there for the next 150 miles then spirited driving for the remaining 700 miles. Zero slippage once broke in and clutch pedal feels stock. I was a little worried for the first 400 miles but after that clutch pedal feel is where its supposed to be. You guys rock! Shipping was fast but unfortunately I never got a tracking number.
