1972 Dodge Colt
Slow down the rate of hit on your ClutchTamer. Keep tightening up the the big knob until you only get about a 1000 to 1200 RPM drop at the hit (just at the point the Clutch starts to grab till it is fully engaged) When you get it right the car should knock at least 5 tenths if not more off your 60 ft. Hoping for a 7 second run for you.
Thanks Grant, you beat me too it.
