I think I should get her down to a 1:26 this year but I have some power steering puking issues as well as crank case venting problems so it will take me a few days to sort that out and then I can start ging after faster times!

The IC was custom and helped a lot as I basically had the same boost on the first lap as I did on the last lap. The factory unit was heat soaked in two laps and then the car became progressively slower.

Very nice car and great times. Best thing is to get the same times with 4psi less. So what boost are you running now?
Must be pretty quick to keep up with Cups. That's really light too. Must be amazingly responsive.
Is that with no / low fuel and no driver I assume?

Can you run E85 in your series? How long are you races generally? E85 can let you run a lot more boost of course but extra boost = extra pressure = less time between rebuilds.

Yeah exactly -- I've just never seen many people do it, and yet it's pretty popular with many other turbo circles.
I'd rather there be an interface I can tap into, rather than rigging up something on my own (I'm thinking arduino-based).

WOW 
Very cool!
Just goes to show how much you can achieve with a whole lot of LIGHT.
Do you have a ballpark idea of how much power you're developing at the crank at current boost levels?
If you have a white Porsche race car...there really is no choice, huh? 
Are you asking whether anybody makes a setup to go with these cars, or whether anybody is successfully using one? While I don't know the answer to the latter question, it does look like a Snow Performance Stage 2 MAF Boost Cooler with the 2.5 gallon reservoir would be perfect, I'm going to set one up eventually.
Aside from the volumetric efficiency improvements that W/M injection gives you as a side effect, by "steam-cleaning" deposits out of the engine upper end, do you think there would be a longevity benefit there, too?
