Don't know, roasted my clutch on the dyno and have not been back yet.
13 psi 300hp 320 tq on a smoking clutch, hope to be back on the dyno soon.
But you can tell by the speed I posted above, it's pretty swift.

Turbonetics 60-1 hifi, to4e housing .60 a/r, big shaft, ballbearing, .50a/r. t4 hot side, stage turbine 5 wheel. Purchased through SFR.
15 psi at 3000rpm
7psi imediate tip in from 2500rpm.
peak torque seems to be around 4200rpm
keeps pulling harder and harder all the way to 7000rpm.
most likely 360-400whp on pump gas.
I have not finished tuning it or dynoed yet and that most likely won't happen befor spring.
I could not be happier with the performance of this turbo. If you don't want to go with turbonetics and ball bearing or the t4 hot side I would sugest a LindseyRacing super61, to4e, stage 5 with a #10 hot side. This would be very similar and cost much less and bolt right in. Other than to get ball bearing I can not think of any other turbo to get for any reason at these power levels.

Found this interesting matrix off the Turbonetics site. The file was too large to post so I am posting the link to the table.

What you need to know before you select a turbo engine air flow.
Here is the calculation to do it L x RPM X VE X PR
________________
5660
L= engine capacity in liters
Rpm=Maximum engine speed
Ve=engine volumetric efficiency
Stock 2 valve-85%
Stock 4 valve=90%
(pr=14.7+11.4
________ =1.78 cfm 2x7200rpmx93x1.78
14.7 _________________-
5660
=421.2 (29.5lb/min
To get lb from cfm x0.07
A better way of doing it not 100% but it helps.

This calculation is for air flow?
So my equation would look like this?:
2.8X6500X0.90X421.2 = 6,899,256

Take 14.7 plus the boost you want to run lets say 11.4 add those two=then divide by 14.7=1.78
take your 2.8x 6500rpm x90ve x1.78= then divide by 5660=cfm that the motor will use under boost
To convert from cfm just x0.07 by cfm you get.
2.8X6500X0.90X1.78 don't forget to divide by 5660 =515. cfm 36lbmin thats what the engine will flow under boost.
Find a turbo that fits that cfm in the compressor chart at garretts web site.
It's not 100% but it gives you an idea were your at any smaller flow and you know that's not right.
