".....So far, I've dyno'd at 8psi and 12psi.  8psi numbers are 494/494 and the 12psi numbers were 560/570.  The 12psi numbers are not accurate due to traction on the dyno.  I had 4.30 gears at the time and it'd just spin as soon as the boost hit.  I did manage 560rwhp before the tires started smoking.  We tried 4 straps in the back and 2 people in the trunk but it was just too violent of a hit for the Nitto 315/35 drag radials to hold onto.  LOL"

".....I hit the dyno a few days ago to see how far I could take the stock fuel system.  With a straight up, bolt-on Stage 1 turbo kit w/optional BAP and boost controller (stock fuel pumps, ignition, etc), I was able to get to 17.0 psi of boost before I hit 98% duty cycle on the pumps.  I was rewarded with 676rwhp and 714rwtq.  Max boost pressure obtained at 3200rpms"

".....I just wanted to give you an update on how the car is doing.  This past weekend I ran at Rockingham Spring Civil Wars event.  Long story short, three 10.22 passes over the weekend at 135 mph on just 16.5 psi of boost.  This is still on the 100% stock long block with the Stage 1 50mm turbos.  I would crank the car up further, but I'm still on the stock fuel system with the exception of a boost-a-pump and the 60lb injectors."
