Gents;
Close to the point where I will send my engine to my builder for freshening. I have two clutch assemblies: A Tilton 7.25” single disc; and a 5.5” Quarter Master single disc.
Craig Taylor explained it to me this way: say you have a round metal disc 8” OD and of sufficient length to weigh 50 pounds. And you also have a metal rod 0.25” OD and at a length that weighs 50 pounds as well. Say you spin them at 60 RPM. If you needed to stop each one by hand, which would be easier?
I get it about the acceleration/deceleration pluses of the 5.5”, but the Tilton definitely looks beefier. What are the arguments of one vs the other as a function of rebuild costs, longevity, and performance pluses/minuses.
