Centerforce makes some badass clutches. They have weights on the clutch fingers that use centrifugal force to make the clutch disc(s) hold. In other words, the higher the RPM, the harder the clutch grips. They do have dual disc units that most certainly will take that kind of horsepower. They are not cheap. It will probably need to be custom made because I am not certain any of their off the shelf units will withstand that. Since however, they provide clutches for 10,000 plus horsepower top fuel dragsters, I am sure they can help your customer.
