I have a competiton 6 puck in my hatch. It's holding over 600hp and 470+tq. Its a little hard on the leg, and defintely takes some getting used to. But it's done me well so far. Tilton Twin Disc is next
For what its worth, I made 400hp and 350tq before my OE clutch let go. But when it did let go it went quick.
