You should be able to look at a clutch chart at your dealer. The factory service manual had a clutch chart in it.
If you want more performance, Id suggest getting a whole clutch kit from eithe EPI or Hot Seat Performance. That will get you a different primary clutch spring, heavy primary clutch weights and for the secondary it will get you a different spring and a different helix that will dramatically improve the performance of your sled.
Clutching is one of the most important aspects of how a sled performance and IMO its the thing that people most often overlook. You can have all the horsepower in the world, but if you dont have the clutching to put it to the ground, it doesnt mean a thing.
