BTW, I can provide clutch kits that will be able to support 650hp in just a regular style 11" Long pressure plate and clutch disc. The button clutches aren't really ideal for street use.

If you do a tear down and find out that your discs have been contaminated or your pressure plate has failed, it would give you another viable option.

If the discs are contaminated it could be that the input shaft seal is leaking, or possibly your rear main seal.
