I was trying to part the whole thing out at one point. Didn't really work out.

Me too. I do, however, plan to sell the car once it's up and running. Possibly a set of injectors and a ring and pinion first.

The next time we have the two lying around maybe he and I can measure.

Does anyone have any more insight on this? It would explain a lot of things.
I'm assuming its the difference in cam profile but I never got any better than 165 psi on a compression test (all 4), 94 block/99 head, 9:1 pistons. Also, cylinder leakage was 1-2%. No complaints as far as power (other than the fact that I'm N/A), but I found it kind of odd.

That's a competition clutch right? That sticker looks like it from my phone.

You're in WI? Everything looks nice, I'm looking for somewhere to get a Megasquirt and have it tuned locally since I don't really know what I'm doing.

Overheats as in slips, smells or drags? Pretty sure I would have heard about this if it were the case. Most folks that spend $1000 on a clutch would not hesitate to call me if all was not roses. A small quantity of early production organics had a tolerance stack issue that them drag. John Wag got one. That issue was fixed last year and that's about it. The ceramic has been flawless from unit #1.

Sorry dude, you still want one
