Another LT1-S dyno result!!
We had a C5 Z06 in the other day to get the old LS6 stock clutch out, and get a new LT1-S with a standard weight flywheel. Here is the dyno results, the only difference between the dyno runs was the clutch swap. It gained 15/RWHP and 13/RWTQ!! Not bad for just a clutch swap, that also drives like stock and can take 700WHP/TQ. Sorry for the poor quality of the photo, its the best that I can get right now.

How is the clutch causing that big of a HP increase? Is it lighter material, or was the old one just slipping some? I've been looking at picking up one of your LT1-SC packages for my new turbo build

This clutch was replaced not because it was slipping, it was swapped because under hard abuse the pressure plate spring would become fatigued and not return the clutch pedal.
We like to post these results to help demonstrate the difference MOI (moment of inertia) makes vs the overall weight of a clutch (which is what a lot of people dwell on). The overall weight of this particular clutch, is close to that of the stock LS6, however, the MOI is dramatically lower on the LT1-S by design. The stock unit is 12" and the LT1-S is 9.5", because of that reduced diameter the MOI is lessened which in turn reduces the amount of energy needed to spin the engine. This is why there is an increase in power even though the clutches weigh pretty much the same.
