No dyno for me, MASSIVE turbo failure
So I was driving along doing 2nd gear pull after 2nd gear pull fine-tuning the car. It was running great at 24 psi of boost. I did a bunch of runs at this level because my knock light kept lighting up and I couldn't figure out why. Finally narrowed it down to the coils had to much dwell and were tripping it. Cool. So I gave the schrapenalknobben a good turn. Sweet, 27 psi no knock. Damn, I didn't have the logger going so let's do it again, but with more boost. Another 1/2 turn later there's sparks shooting out of the hood vent. WHOA! ****, the turbo just let go. Lucky for me the car was still running, but with a large exhaust leak so I limped it home 3 blocks and found this:

The motor seems to be fine, the turbin just snapped off and had its way with the exhaust housing. So it looks like I'll be ordering a GT35R
So the moral of this story is, stand behind the cars at the dyno! We are really luck this didn't happen at tomorrows event as it could have really hurt someone. I still plan on coming down to MAC to observe, but in a not so fast faded red Audi....
