Assuming you were talking about a 930 transmission, the stock clutch should be fine with less than stock boost pressure. If you’re talking about using the 915 transmission in your converted car then the center force is a pretty good option although heavier than the aluminum versions of the sachs clutch. As stated before the sport clutch for the 915 could hold 10 psi pretty well.
With the stock 930 clutch, even stock boost pressure in colder climates can overrun the pressure plate. I wasn’t very impressed with the stock clutch holding power Of a well running 930 engine.
Are used three different clutches in my 915 to try to hold the power, one was a power clutch which held pretty well with about 10 psi next I tried a sport clutch I believe it was and then finally it was a center force and the Centerforce held the power the best at over .8bar.
Turbo powa!
