How much can a T1 clutch take?

[Holley]

Would it be ok with a regular 12psi TII setup? How about 14psi?

I have a nearly new one here (like 500 miles), would be nice to put it to some use ...

It starts to give up at about 250whp.

I run my stock Advance Auto Parts 92 Daytona Turbo 1 clutch on my 523 trans with a large spline in my L body to the tune of 12.50s at 22-25psi.

Haven't experienced any slippage yet. This clutch will be replaced with a 4 puck this season.

It really depends on the brand. I had some aftermarket T1 clutch slip at 12psi.
