Patrick, I am always up for the strip... Lets see how the weather is... There is an event on the 18th so the 25th would be much better... I am also going to Pitt one weekend in August just not sure which one yet... Will go a few times this summer and fall...

a.k.a. you read that on AZ?
Anyway, has anyone got any guesses where the cast internals in the 3.0T will give up and cause an engine failure? Torque levels/power levels guesses?
I sure hope APR pushes one to failure so that they know..if they're using a TVS1900 that blower is likely capable of around 500-525 wheel horsepower and I have a sneaking suspicion that is where the engine will give up.

Speculation is around changing the existing, with a longer nose on the barrel to allow for longer screws, but again there is a lot of hearsay around this, there would be issues with the size if the inlet, restrictions, etc - over going with a new SC.
If I had to guess on the failure point, I would say connecting rods, I have already heard of some failing in engines that apparently were not forged correctly.

I think this guy was OEM Audi tune; Complete Engine Failure - 857 Miles on the Odometer

I have heard of two different well running S4s that failed within a month of getting revo tuned. i.e. needed a new engine type of failed. As you guys know, I have no dog in this 3.0T race, so as an impartial outside observer, that's a bit odd to me and needs to be investigated. Get a look at Tsivas' thread where he posted the mapped logged parameters for all the tunes. He posted it on audirevolution...maybe AZ too. Incredible.
I really hope that trend doesn't continue. We had a REVO tuned guy at the dragstrip with us in April and he was so quick he was scared to run anymore out of fear of causing damage. Another REVO guy at a local dyno event had great results, but mentioned that he also had some problems he was trying to work through (trying to navigate TD1 etc.).
It's like the old saying...if it sounds too good to be true, it probably is.
