This summer I'm going to upgrade to a high performance clutch,
because I'm eventually going to stack a fueling box with my already
installed equipment. What clutch is best for 350-400 HP , but won't
chatter and have good"feel" for towing and everyday driving around
town.

 

The dilemma seems to be "do you want it to hold, or do you want it to be buttery smooth like a stocker? In this BHP range, it doesn't seem that you can have both."

My South Bend Con OFE never slips at the RWHP levels in my signature, but it will chatter slightly on engagement at engine idle speed under heavy load, like backing our 5th wheel into its covered storage site. The "work-around" is to bring the engine speed up to about 1000 RPM, then slip the clutch into engagement. It takes some getting used to, but the clutch doesn't care (it never smells or chatters).
