I dont know about 180 flywheel at 6 psi? that seems pretty low. On the same note I dont think 10 psi will get you 220 at the wheels with stock turbo and tmic. So whatever that is worth, thats what i got.

Ya, i beleive you made that, i think you may have been a little closer to 9 than you think, I also think thats a timb bomb setup and ill bet if you did 2 or 3 hard 3rd and 4rth gear pulls it would blow up. You need more fuel and something to control the bigger injectors. 180 FWHP at 5-6 psi is what the S4 made stock, S5 as you know was 195 or so, thats FWHP also.

Oh and how did your car compare with his?
Care to comment astrochild?

There was a big difference in low end because he removed his 6 port sleeves and opened up the runners, and my six port sleeves still operate like normal. Top end was actually within a few percent I'd say, probably just due to the weight difference of our cars. If he got a good launch and stayed above 5k rpm, his car would fly down the quarter mile track. But who knows.... I've done so much $hit to my engine since then, there's no way to tell other than taking a trip to Woodburn.
