Hmm I am not sure about exact #'s but let me give some futher background, 
they are junkyard motors, 130,000+ miles, not headwork, stock cams and 
bottom end. Junkyard T3 super 60 turbos and a SDS programmable efi. I would 
estimate from the quarter mile  time/MPH that the power is around 330 at the 
crank, give or take.
One of the things to remember and I get in trouble with this myself that 
it's not so much boost pressure but airflow at that pressure that makes the 
power.
I have an 8:1 turbo motor in a street car and I feel like the bottom end is 
a little to weak, I would really like to see sometihng closer to 9:1 for the 
street.
Let's take this off-line if you want to discuss more, I'd be interested in 
hearing more about your set-up
