That,s funny, I noticed a “cold effect” to, was out at night at maybe 45f a couple of times, engine temp half way up to 180. Rolled out of a parking lot in first and then just stomped on it, no clutching, straight line and i just “lit'm up” like I was on ice.

Here is how I did it:
Porsche claims 201 at the crank my base line dyno showed 164
164 times 1.22 is about 201.
226 times 1.22 is 275 crank.
I will assume right off the bat someone has a better way of finding these numbers but this is the "logical" way to me.

Sounds like sound logic. Good enough for me. That’s about what I came up with using my own variables.
Heres How I did it. Using TPC’s claims of 70-80 hp and shaveing off the lowend by 15%...I get 60hp boost at 4.5 PSI.
60 (boosted hp)/4.5 PSI (boost) =13.3hp per 1 psi boost. So, 13.3 hp x 6psi=79.8 hp. So, about 280hp total
I’m probably dead wrong too.
Glad your at 6 PSI though. To get 7 PSI, my SC revs will probably be past recommended 14krpm's, and may be past the point of diminishing returns (more hp to spin it than it can put out).
