Counter weight is used to add pressure to the clutch disc as the run progresses. It uses the centrifugal force generated by the spinning of the clutch on the fingers. As the engine turns more RPM, so does the clutch and thus adds more pressure for every RPM turned.
How do I tune with counter weight?
The best tool you can have when tuning a clutch is a data logger that records Drive Shaft RPM, Clutch RPM, and Engine RPM. This is so that you can see how well the clutch is able to match the engine rpm, while not allowing the rear tires to accelerate too quickly causing the tires to spin. A good graph on a run will show a small amount of slippage in the clutch to engine ratio on the gear changes, which keeps the car from being disrupted during the gear change! Using counter weight is how you adjust for these changes in track conditions, engine hp, air, etc... By adding and subtracting the amount of counter weight used, you can better tune your car for quicker E.T.
NOTE: When making counter weight adjustments, you must also figure the amount of actual base pressure you are running as one directly can effect the other!
