What weight are you running
Hey Guys there are 3 weights for the flywheels 40,30, 20, for Mcleod. If you are doing alot of parades and slow driving the 40 lbs will work best. the 30 lb is in the middle of the road with helping remove 10 pounds off the back of the crank and help to let the motor rev quicker but also storing the torque energy to get the car moving. 20lb flywheel is best at roadracing and quick running up and down the RPM scale. With a light weight car, the 20 or 30 work better.I have run my 452 with both a 40 lbs steel and a 22 lbs aluminium flywheel. With the same motor and tuneup the car was .2 faster with less weight in the 1/4 mile. A car under 2,700 lbs doesn't need a heavy flywheel. IMO. You need to build a drive train that can hold the HP and torque. The twin street disc setup should hold just about any motor in a cobra that is under the 800HP rule and still have a light clutch pedal. Rick L.
