It totally depends on the setup. Louis Anaya (TurbochargedSER) tuned a B18C with JE pistons and Eagle Rods and a very big T3/T4 turbo to 375whp with only 7 psi of boost. If you tried that with a DSM turbo or a straight T3, the turbo would probably kill itself trying.

I heard the run was actually at 10psi, and I don't think Louis did the tuning

You must have forgot to mention he is running a T76 and it spools about 8700 rpm then pulls HARD until 9k where he shifts...

Totally depends on the setup, I had my Integ dynoed a few weeks ago, I have a Rev Hard stage 2, 310 Injectors, VAFC. 255lph pump and a bone stock 95 GSR engine. I was also using 93 octane gas.
~~First Dyno pull was 274hp @ 10 psi
~~Second was 283 @ 10 psi
~~Third was 289@11 psi.
Hope that helps, that was stock compression and everything.

My buddy here's got a mid 9:1 compression GSR with skunk2 manifold, 60-1 turbo, and made 298 at the wheels at his reported 11 PSI.

I believe him, his car hauls ***.

I know at 8lbs i am making a bit over 300whp on my custom set-up running 11:1 compression on a b16a. The head is ported, skunk2 intake manifold as well as a 60-1 t3. I know running 14lbs of boost i should be laying down hopefully near 400whp, not bad for a little 1.6L. Compression and turbo size become the key factor is laying down big horsepower #'s, as well as displacement (gsr stamped out to 2.0) and flow of the head.

Of course it can be done -- this isn't the 80's anymore I'm almost finished building my B18C1 11.5:1 and plan on running 10-12psi on pump gas. Just say B00 to FMU!
