Mongo, you might want to check the thread for the Jannetty Super Street Brawler. I know it's a different blower, but the fuel limitations should be about the same.

With 93 octane, he was running 700whp with 11psi. On e85, he reduced boost and was running 725whp on 9psi. So you might find a sweet spot where you can make more power with less boost. The other thing is, you are adding a cam which will, I assume, increase the fuel lobe meaning that the lt4 fuel system can do more...once you have the e sensor, really the car and tune should auto adjust for the amount of e you are running. I think I have the same scenario where we expect the e85 to really be e60 or so.

Fyi - I am doing the exact same thing as you. We should be starting my build in a couple weeks. Only difference is, I am not adding the aux fuel, but am including a boost a pump.
