Mike,

I'll probably start on it around 1 or 2 in the afternoon, and I'm still in the same house, so please stop by. I wish I could go to hershey tomorrow, but my band is playing a cancer benefit on the Eastern Shore, so I can't make it.

You can always toss in a couple of gallons of Xylene to that 94 oct Sunoco, get you up around 97

You can run 30psi fine with the right setup. A little water and the right A/F. Laust has done it I believe...

I don't think we've ever pushed Laust's car beyond 25psi. With 97-octane, you can actually run about 20psi on the GURU chips (custom for this boost) along with the 2-degree more advanced ignition maps. The thing about simply turning up fuel-pressure to compensate for higher-boost is that you richen you mixture across the board. Idle will be too rich and so will partial-throttlle mid-range.

I thought it would have been about EGT's also, not just A/F's...
