[s-cars] No dyno for me

[Jim Green]

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! FECK, 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:)  Hey Hap,
what size A/R are you running on your GT35R exhaust?

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 going down to MAC to observe, but in a not so
fast faded red Audi....
