Ram cinterd iron clutch help

[Stick Racing]

Counterweight works best with cars that have big motors with small tires.
The idea is to use low base to slip the clutch and get the car rolling off the starting line without blowing the tires off.
As the rpms increase, the counterweight adds more pressure to lock up the clutch..
Big block stockers with a 9 inch tire and a high horsepower 10.5 tire car are good candidates
for counterweight pressure plates.

If you have a car that leaves the starting line close to or the same rpm as your shifting rpm,
chances are you do not need any counterweight.

Andy:
Do you use a data collector or two channel tach to monitor clutch slippage?

Playback tach. No electronic gadgets for me.

I'm a grass roots guy that don't want electronics driving my car. Two step for the starting line and a playback tack so I don't have to have my eyes glued to the tach all the way down the track.

The tach will show how far the rpms drop at gear changes and how long it stays there. That will tell me how much slippage. Granted, it's not as good as a data collector but it leads you in the right direction.
