I've been on this forum since the Boss 302 was introduced, there seems to be a common thread with clutches, and MT82 trannies, It seems that as long as the clutch is functioning at 100% the trans lives a long life, as soon as the clutch degrades, so does the trans, to the point that.. if it grinds once or twice, its time to do the tranny as well as the clutch because it won't be long before the trans goes tits up. If I owned a car equipped witht he MT82, I would just go out and buy a Exedy Hyper single and install it, along with an MGW shifter. I think the Hyper single is the go to clutch for these applications, sure, release is a bit harsh, but we've put thousands of race miles on these with no issues what so ever. I'm so sold on single disc clutches that when the one in my 07 GT500 went south (a factory twin disc) and Exedy didn't have an application, I was able to source a similar model from Spec. there has never been any issues since, and that was 40K miles ago. I like simple clutches, even though they may be more harsh, and harder to hold down, because they have less crap rotating around the bell housing, I don't really see a need for a twin disc clutch unless you may be drag racing it. The Spec clutch in my Shelby is good for over 600HP, and it's a single disc. Once the trans starts to go it would seem that the Calimer is the only game in town (or at least Calimer parts built by someone else). I looked into doing this but was talked out of it by Joe Aquilante himself, he calls things straight, and he pretty much said it wasn't worth the time to RnD an Mt82 because they just send it out to Calimer and let him worry about any warranty issues. So if Phoenix is using Calimers, then that's good enough for me. They don't seem to have many failures, but again.. the Hyper Single and MGW shifter is used on their cars as well.
One last thing, the guys at Forte's in St. Petersburg do resto rods as their main line of work, they are starting to go back to cable operated clutches instead of hydraulic for a couple of good reasons, 1, for some reason, hydraulics are adverse to being power shifted, I've seen this before back in the 70s. reason #2 is that a cable clutch offers much more adjustability than the hydraulic, when they are playing mix n match with different engine and tranny combinations, they sometimes have to pull tha trans back out to get the correct shim, or customers drive the car for a year and the clutch is low, so again, they have to go back in and add a shim. None of that happens with a cable ( or mechanical) clutch,
