The super sprag setup that uses the 4T80E clutches is a 5 friction plate setup (a 10 disc pack). And, you're right. I am limited to only the high energy frictions. But, they work good, and I actually prefer them, so that's a good thing. The 4T80E pack is more than enough to be effective. In fact, maybe a little too effective,.. for my particular track, anyway.But you are limited to the high static clutches with the 4t80 race
It's effective enough that I feel comfortable simply using regular steels in that clutch pack. Practically, zero heat marking of the steel plates in the intermediate. I even added springs to all the return spring pockets of the intermediate piston in attempts to soften up the 1-2 shift, to no avail, by the way.
