I am always impressed with the crazy horsepower out of such small engines. What is the actual timing at 26 psi.

 

^^^ I don't know what the timing was at. My tuner is supposed to email the dyno sheets to me, so maybe it will say on there. I will have to get back to you on that one. Good question though. I know that E85 burns cool, so I'm guessing the timing is pretty advanced. I'm kind of a retard when it comes to tuning. Just know to take stuff apart and put it back together.

 

this doesnt make sense.

Op I havnt run e85 at that power level but just pulling this off of my head. ur injectors should b good for 60 or 70 psi which is a good bump over stock, the 750s at that pressure should b good for close to 400 on e85. there are tons of injector calculators out there that will answer this question. I would def get two tunes, one for each fuel. e85 is def the way to go, i wish i could get the stuff, closes place to me is a hour and a half

 

I was using 550cc injectors on 91 octane and got up to 384whp @ 16.5psi. That was with a Garrett GT3076R on a built B20 bottom & '99 B16 head with CTR internals. When I ran 109 octane, I could bump the boost up to 21psi. Not sure what I was putting down to the wheels, but it made a huge difference. You should be able to hit 400whp with the 750cc on 93 octane no problem as long as you have a good flowing turbo and a proper tune.

I moved up to 1000cc injectors and with the E85 I am maxing them out at 26psi. If I used the 109 octane, I wouldn't be maxing the injectors out. I wouldn't be able to run as much boost either. E85 is cheep race fuel and close to me. And if I need to, I can switch maps to run the 91 octane.
