What clutch should I go with?
 

Trying to figure out what clutch I should go with. Debating between a twin or a triple and want to see what people with similar setups might be running.

It is a cosworth 2.2 with an hta3582r and shep trans, ID2000/twin pumps running on e85. Old clutch is slipping at around 22psi and she is making around 550 on a mustang dyno and that is as far as we can go with the clutch.

Not sure if I can get away with a twin or I should just be safe and go with a triple. Aiming for 35-38psi hopefully.
Just looking for recommendations, I don't care much for driveability as its not my daily driver.

Car will see some track time.

How many ftlbs? What kind of track?

The car sat for a while, but I finally decided to stretch her legs and retune. She made 670/592 on the previous tune, and my exedy triple is slipping (its been in the car about 5 years.) Hoping to push it a little farther this time, but odds are numbers will be around the same.
Hoping to hit Sonoma and Thill. Possibly some 1/4 mile runs but I don't plan on that as of now.

And a triple isn't holding it? Hmm..

Road racing with 600+. You gotta get video of that.

That triple is probably just worn out and needs a rebuild. Or you have an SD cover on the triple and you need to switch to an HD. I have a triple in a car here; Evo8, 2.4LRwith a 6466 strapped to it making 830whp and 670wtq. Holds it just fine.

Either way, an HD exedy triple is more than enough for your needs.
