I was running 24psi and C16. But you should also know that my head was lifting very badly at the time. My temperature gauge was past the H when I crossed the finish line. I later found out my head was badly warped. And then a while later I found that I had low compression in #4 cylinder.

So my point is, the engine was not 100% healthy on that run. I bet on a healthy engine with that turbo and boost, I could have hit 121-122mph.
