Well duh. That was never in doubt.
And YOU'RE WELCOME.
Quick update while making dinner more later:
217/166 7.2k compared to 191/152 before.
Now: RB header/midpipe, megasquirted, cnc head. Ati damper gives 145 crank pulley so I put the 88 on the rotrex to spin to 8k without overspeeding compressor.
Numbers seem low but: 7psi. Yes, seven. I do jot seem to be flowing as much air from the rotrex as I should. I am pretty sure there are no shop rags in my intake. With the bov completely off, it would still make some boost, so I ccan't see intake restrictions as a possibility.

In other words, you gained some torque and a titch of power from the MS and CNC head and header/midpipe, and the rest of the HP by turning it to 8k rpm.
Time to up the boost sir.
Edit to point out that of the actual guesses mine was the closest

I'm out of boost is the point. I can't run the compressor any higher without over speeding it. I should be seeing at least 12 psi, but I'm only seeing 7. This is not readily explainable. there are no boost leaks, there are no intake restrictions, this leave only that the compressor is simply not flowing the air it should, which does not compute.

Yes, 1psi less, and he made 27hp and 14ft/lbs more.
My guess is you got sent the incorrect Rotrex.
To give you an idea of gains, 1psi on Laz gave us 13hp today. That means 14psi on Richards would clearly give us 308*. Richard. Up the boosts.
*Non-logical based prediction.
What's wrong is he's making the 14psi predictions off the compressor he paid for, so he shouldn't of needed a bigger Rotrex.
