At 65psi base you might do ok, I am going to give it a try with these and see how far I can make it. I am thinking about 600+ to the tires with a unlocked converter, th400.

Nate at Nasty Performance said I could use 60lbs for 8-10 psi on my 347. After reading all the threads I wonder if that's big enough.

You should be okay, weve been factoring 25% larger injector for E85 vs gasoline, and its worked quite well.

A injector thats 80lb @ 3 bar will flow 92lbs @ 4 bar, you should be okay with that.

If that question was for me this is what Nate said.

"E85 requires about 33% more fuel volume than standard gas. So if your goal is to get to 550rwhp you are going to need at least 750rwhp worth of fuel. 60# inj. should make that kinda power with good fuel pressure. I would rec. our Stage3 Street kit with the Dual Lonnies/Racetronix fuel pump setup. It has the best reliability and will handle the fuel delivery you need…very safe. I would forgo the meth as it is just a patch for not enough fuel. If you wanted more power you could just turn up the boost the fuel system can handle it."
