How much power with 750cc's and e85?
Does anyone know what can be expected with e85 and 750cc injectors?
Also, what will it do to O2 sensors? No need to worry about cats luckily. :) |
Re: How much power with 750cc's and e85?
What fuel pressure? What is your BSFC? What is your expected air consumption?

Re: How much power with 750cc's and e85?
If you're running anything larger than a 16g, I think you'll be needed more injector. Your duty cycle might be too close for comfort.

Uhh, I was running 720's with a FP Red, they can handle more than a 16G. I maxed out my Poopra pump before I maxed out my 720's. Even on my old 20G setup, 550's were plenty. Considering that E85 needs roughly 20% more fuel to have the correct A/F ratio at WOT, your 750's now become the equivalent of 625's on gasoline, which is probably good for 25psi on a 50-trim.

Or just have some awesome EMS that can control tons of injectors. Why have a set of four 1600cc injectors when instead you could have sixteen 450s!!

I thought it was closer to 25 or 30% more. Either way, those should handle quite a bit. |
Re: How much power with 750cc's and e85?
Couldn't give you a power number with those injectors, but I can let you know that either E85 or leaded 110 ate up one of our O2 sesnors. However, Santa has been running E85 on a close to stock fuel system with no adverse affects as of yet...

Re: How much power with 750cc's and e85?
I was at 105% fuel injector on my 780cc with a 60/40 mix of e85/92 octane at 24psi on a gt 35 dynoed at 400whp.
Now I run 1600cc injector at 58% duty cycle at 27psi on 60/40 mix. Jim |

Well, I have an RRFPR with whatever baseline I choose, walbro 255, an sc61 but right now maybe no more than 20psi because I was dumb and got the 2bar posative map sensor instead of the 5 bar, which I should have.

Re: How much power with 750cc's and e85?
I've got twin HP Walbro 255's, 720cc primaries and 450cc secondaries. I should be ready for E85 next year. That will be replacing my 100 octane unleaded I've been using for years. I've been hearing great things about it.

What managment system will you use, if you don't mind?

What about cars meant to use e85. My dad's van is set up for it, and he hasn't had any issues I think. I think it threw a CEL but it went away? I'll ask him, but he uses e85 all the time. It smells like dinner when he drives off.

Use the E85, dont worry about anything except for the possibility of corroding the aluminum pieces in your fuel system. Even that I wouldnt worry about it to much with how much you drive your car. 1.79 for 105 octane, hell yeah.:) |
Re: How much power with 750cc's and e85?
Speaking of the stuff at bobby and steve's gas, I get less knock on my 60/40 mix than I do straight 111 race gas at bobby and steve's. That doesn't make sense since my 60/40 mix should be around 100 octane or else bobby and steve's race gas is shit.

I think it smells more like popcorn

I havent researched it enough to know the true answer. |

BTW, does anyone know what kind of long term damage an aluminum piston will suffer? Maybe none since the fuel is burning in there? |

It is my understanding that ethanol needs water to be present to really become corrosive to aluminum. Either way 7,000+ miles shows no detectable wear. I would be more concerned with the rubber fuel lines before the fuel rail. |
