Well been around a while, just got rid of everything I had and cleaned house. I am running E85 due to in the Midwest it is plentiful and cheap. Also it is emissions friendly so I would be exempt as long as I pass a visual. I am changing my plan from a HP engine to a Torque monster and no better way to do it them with big compression, I was thinking 14:1 but in the winter the mix is more like 60% alcohol so I want to avoid detonation. Generally with the advantage of majorly advanced timing and way higher compression you gain about 30-40 percent effeiciency but use 30% more fuel so it equals out consumption wise. Torque and HP is definetlly boosted along with a lot better throttle response. The down side is you cannot let fuel sit, it attracts moisture so you have to use it up. What I will do is store it in a 55 gallon drum and mix it to my desired spec to maintain consistency. Around here 105 octane aviation fuel runs about 10 bucks a gallon, at the same octane E85 is 83 cents a gallon, that is below 10% cheaper a gallon. I am running a SN95 computer with a Moats Quarterhorse and Jaybird tuner so I can change timing, firing order and injector sequence along with get rid of batch fire to further increase efficiency. I think I can get 500 HP, and about 30 MPG out of it when all is said and done, I am going to have to change my roller cam to something different with less overlap to maintain compression though. Some guys I have seen are running 14:1 with boost and still not detonating. I am building a driver that has to run in cold weather so I want to keep compression around 13:1 to allow for a slightly higher gas content for easier starting below freezing. I am going to be running 33/12.50 tires, a T19 with a 6.7:1 first gear / 1:1 fourth and 3.70 gears so RPM should be about 2800-3000 on the highway.
