When I ran a T-10 we would set up the pressure plate without roller assist and about 2700lb. I ran nothing but a good standard disc material in the disc itself.

We found that it made it diffcult to shift at higher RPMs.

For Sand drags the McLoud 10.5" 4 puck bronze disk under a 11" Ford Long style adjustable pressure plate was the ultimate. We got by with around 800-1000 pounds pressure on the disk. No heavier than a 30 pound steel flywheel. High range 1st to 2nd 2.32 to 1.69 second using 5:57 rear gear. With a 2.78 first to 1.69 2nd we use a 5.38 rear gear. Either was perfect for 400 to 500 horses running 5.5's to 4.5's for ET's. Our weight were from 3200 to 2500 pounds using these ratio's. When I ran a Muncie it was with the 5:38's and it worked very well but became a little fragile as the power increased. The Ford Top Loader is the ultimate and now that Liberty has gone from the Liberty pro shifted style to face tooth engagement is it super fast and super durable.

For mud bogs we used the exact same setup but in 4 low using 3 and 4rth for the over the tire really deep mud. Best way to wreck a clutch was to grease it up in deep mud and slip it real bad. The trick there was get the right gear and no shifting.
Best pass during 2015 races 3.092@104.4mph at Albany OR. All motor single 4 on race gas.
