A friend has a 2002 thundercat with black magic pipes, and a black magic clutch kit to match, I think its a woop ### kit. We are installing NOS fogger system and need to get the rpm to drop by 500, from 9000 to 8500. It has bm 64 weights now what should we change to. Is there a weight to rpm general rule. Thanks

I believe the mass is inversely proportional to the square of the speed (rpm). So I would try [(9000x9000)/(8500x8500)]x64g.=71.75g .Make it 72grams and go from there. This is assuming the profile of both sets of weights are the same.
