I run a stock diaphragm and a heavy duty disc. I think the new engine build this year has found the next weak link, and more power necessitates a better clutch. I haven't pulled it apart yet, but there's no oil leakage on the bell housing and I suspect it's just a power issue.
Question for you - I would consider going to a quartermaster or similar steel flywheel, smaller clutch, etc, but am concerned that a true racing clutch with a solid center disc is going to be more of an on-off switch, and I worry about the jolt to the differential, which fails every 3-4 years anyway. That, plus as you know the typical vintage event requires poking around the paddock through pedestrians - hard enough with the close ratio gears and I'm slipping it a fair amount below 20-25 mph anyway in 1st.
Suggestions? Can I make a racing clutch work? Will I burn it out quickly with slippage? I like the idea of the lower rotating mass,(though I do run an aluminum flywheel, I think one of these would still cut it down), but am worried about other consequences.

It looks like you got a well-deserved 5th overall in the K-Cup & had a great race, and some tough competition!

The Kastner Cup race is at the Pittsburgh Vintage race weekend at Pittrace next weekend - great track north of Pittsburgh. Looks like we will have over 30 Triumphs racing, and the Western Pa Triumph Association turns out a great crowd of street cars. Lots of other good racing too. Weather is looking good. Check out the racer list. scroll down for the Kastner Cup list, which includes a Group 44 GT6 and a Kastner GT6 - fantastic GT6 turnout. http://www.pvgp.org/2018-historics-race-entries/
