GT2876R 17.5PSI 375hp/356tq

Played with timing and got 10hp and tq or so, but didn't get much more from increase it any further so I backed off.
I upped boost controller too, and even with 16.5psi vs 15.5psi I only got a few HP, so my belief is I'm maxing out the T2 manifold at this point, or I need to degree my cams.

93 octane, -22cc pistons, 1.0mm head gasket (about 8.7:1 compression.)
Running 17 degrees of timing around 4000 rpms, and then 18 degrees around 5400, and 19 over 6000.

Great numbers!

I'm guessing you are right about the exhaust side choking it off and not allowing you to use up all of the compressor available. You might only gain a few HP with boost increase but your torque peak should still climb.

Are you still rolling on stock wheels with that power?

I have 235/45 R17 on the rear. (DZ102s)
I had around 330 ft/lb of torque on old cam/engine setup and found it undriveable with the stock 15' so I upgraded then.
