You wont get an organic one that will hold 220bhp without slipping. ive got a LUK that aparently holds 210bhp, but is slipping at 176bhp. i am running 200lbft of torque though. thats what you wanna go on. there is people out there that can modify a performance cover plate to give it more clamping pressure so you can hold more power and torque with an organic. but i dont have any contacts im afraid.
