why dont you have the compressor upgraded to a 20g wheel. The 20g will flow 400whp as long as that turbine can handle it...which is hard to tell. Its a quick spooling turbo so i most likely has a smallish turbine.

To be honest.. if you buy a greddy turbo kit and change things around or try to upgrade to get your high hp goal, than why buy greddy turbo kit at the first place?..
i am taking the greddy the way it is and upgrade at min cost.. hg injector, and my own labor..
if i want 400+ hp i go with gt30 ..

Experience What it can do. it only 2mm hg. i stop at 13psi because clutch won't hold anymore, i still end up with more hp and torque.
fyi, im making a little bit more power than you are, on a dynapack on stock compression, 7.5 lbs, 550cc injectors

Well here is the basic map for the Compressor you are working on:
at 13 PSI with a 1 PSI drop across the FMIC, you are looking at a Pressure Ratio of 1.95.
If you are making 13 PSI by 3500 RPM and keep it until 8000 RPM you CFM numbers would look like this - Compressor Map Calcs
Plotting those onto the Map gives you a efficency window of this:
This is assuming everything is perfect your efficency is falling off on the top side to the point you are at roughly 68% (and most like less as this assumes perfect conditions)
Getting more Info and finishing this post up tonight, but I think that attempting 13 psi on this turbo is a bit out of its range. All you would do is generate alot more heat on the top side which would result in a loss of HP where you thought you would have more.
