The clutch in the MT is a dual mass flywheel. A dual mass setup improves overall engine reliability, specifically for all rotating internal components (crank, rods, bearings, cams, lifters etc.). This is because of increased dampening of engine vibrations.
I supercharged my JT and all seems to be well so far with the stock clutch. It's been great off road at high speeds, and no issues towing a camper over 1100 miles with mountain grades between 6-8% up the 395 in California. (average mpg of 11.2), and I'm running 37's with 4.56 gears. I did a pre and post SC install dyno and wheel torque went from about 220 ft. lbs to 290. I was hoping for over 300, but the tune didnt do much on playing with timing to get more power so it is what it is.
While Aisin seems to report a rating of 370nm which is ~272 ft. lbs. I find that to be too close to the stock engine torque spec of 265 ft. lbs. and would expect margin, unless Aisin is stating their rating inclusive of a significant amount of margin.
