E85?

[95talonracer]

I am also running E-85 and have had alot of success with it. I am running a 11.5-1 and 30psi with no knock. I have a 255 and 880s which are at a little over 90% duty. The thing really likes this fuel.

What size turbo are you running? I couldn't see running much bigger than a 16G at 30psi with only 880s on E85.

I have a 20g td06. I turned the boost down to about 27 or so now until I log the duty cycle but otherwise the AF is 11.4 and there is no knock at all.

Any idea what it's making for HP?

Looking at dynoing it at the end of the week if anyone has an opening for Friday or Saturday. It hit 305 on Regular 92 gas at 20-21 psi so I am assuming it is up a bit from there as it feels much better. Any guesses?

Pao,

There are a few things to consider when using E-85.
Pro's:
-Higher octane (R+M/2) of 101.6 for E-85 (averaged) versus 92.
-Cooler burning fuel (due to the alcohol content), this helps cooling of the combustion charge
-Availability/substadized pricing
-The higher octane allows you to manupulate timing values and the boost threshold compared to knock/crazy intake air temperatures.

Con's:
-Lower heating value. That means you need to burn more of E-85 compared to unleaded gasoline to get the same amount of work (energy) out of it. This lower heating value also shows up in gas mileage (usually not directly compared to the differences).
This also shows up in the massivly required fuel system. It is typical to require 30-40% more fuel to make sure you have "enough".
-possible corrosion. I have heard of case studies and examples where people have run year after year without issues using OEM fueling systems, but there is a reason the OE avoids alumimum on E-85 vehicles.
-Different stoic AFR. Tuning in Lambda versus AFR usually solves headaches.

Pretty much in a nutshell in order to run E-85 you need the fuel management and fuel flow capacity for roughly 40% more than you normally would need (it is always a good idea to error to the "to much fuel" side versus not having enough). You need proper engine management, and you need to pay attention to summer vs. winter blends (or use a tuner that knows the difference).

Welcome to Mitsustyle, and I guess you didn't get your email...I won't get your wastegate in until later this week.

How's gas milage treating you? You're running it with just the one 255 pump? Most people go dual with at least a dual pump.

You can run a single pump in lower HP applications with 880s or 1000cc injectors. If you are making a lot of power, you will need dual pumps and 1600cc or more.

If you know so much about it why are you asking questions?

I never ran it, like I said I want more personal information.
