If you can run 5-6 psi you should get 6 months out of it. 8-10 psi on the stock compression is a little risky IMO. The stock turbo only ran 11-12 psi on lower compression.

Running 5~6 lbs boost on a 10.6 static compression motor gives a effective compression ratio of 14.2~14.9, which is right around a 951 motor at 8.0 running 12 lbs of boost (14.5).
Running 8~10 on a 10.6 C.R. gives an effective C.R. of 16.4~17.8 which is like running 15~16 lbs boost in a 951 (16.2~17.8 effective C.R.)
So this shouldn't be a problem as long as you provide the fuel to match it and a proper timing curve. Also, since Roastin944 is in Colorado (approx 5k foot elevation), running a guage pressure of 8~10 lbs is approx. equivalent to running 5.5~7.5 psig at sealevel.
