curious about flywheel weight etc....!
so I have been keeping track of clutch setups I have run in the past and current. see below for stats
McLeod Street Extreme (Drag Week Setup)
Pressure plate 20lbs
Clutch disc 5lbs
Aluminum flywheel 14lbs 8oz
Clamp load 2400lbs +/- 5%
Pressure plate 25lbs
Clutch disc 4lbs 6oz
GM nodular Iron 31lbs 2oz
Clamp load 2800-3200lbs
Mcleod RXT 1200
Pressure Plate 12.25lbs
Clutch Discs 3.17lbs X 2 = 6.34lbs
Steel Flywheel 29.43lbs
Adapter Plate/Mid Ring 5.86
My first setup was the center force II and the entire assembly weight 56lbs, this resulted in the easiest to drive. My second setup was the Street Extreme at 35lbs, little harder to drive, way quicker RPM, not the greatest at the strip. The new setup will be a RXT with a steel flywheel at 47lbs. I'd expect this to be a great middle ground, well see how well it works at the track.
I will honestly say for a real street car despite the power levels and your into the drag strip, you will need a steel flywheel. Getting a 4000lb race weight car to leave the line half decent requires some stored energy. And after talking with fellow racers it seems the trend currently is to run big flywheels and small clutch setups, it seems to yield a great medium in leaving the line and accelerating your car.
