833 hold up to 500hp RB

Yup. If I was starting with nothing, I would use a 10.5 Long pressure plate and the SI disc. But I already had the BB/Long cover and flywheel.

Unless you are running something running in the low 8's I can't see the need for a multi disc clutch. I absolutely have no use for the dual disc 10 inch or larger clutches. The combined rotating weight makes it almost impossible to shift above 6500 RPM.

And if you already have a flywheel the BB/Long cover is a good deal. The issue is getting someone willing to make the cover adjustable. Although I ran mine unadjustable into the low 9's.

But just so that we're all clear here, you're talking about a drag car that's running 9's. Most of the cars on this site have probably never even seen 6,500 rpm, let alone shift there (or above).

Meaning, the vast majority of people here have absolutely no need for that kind of clutch. I'm not saying you can't run that clutch on the street, you obviously can. And if you dial down the base and use a good amount of counter it probably isn't even a PITA on the street, because on the street you'll be shifting at much lower RPM's and won't have to fight as much of the counter.

It's always about application, and yours is pretty specialized. Not that it's a bad thing to be that specialized or that fast, but most aren't, and that changes the perspective.
