My understanding is that E-85 is higher in octane and of course its cheap . A friends cousin has a car that runs on E-85 daily w/o the converter box. Ive been told by a few ppl including him that it is ok to run it but then in order to turbo and all i would just need bigger injestors.(i.e If I ran a 35r, instead of 1000cc it would be more like 1200cc) but just wanna know if anyone else heard of this?

He is running this on a fully rebuild LS

 

I heard you will need bigger injectors if you wanna run E-85, not sure tho.

 

you guys clearly do not know what you are getting into.

I hope that you guys are running Kpro and are tuned for both types of fuel. Pump will require one tune and e85 will require another.

e85 has a much much higher octane due to its high alcohol content but it requires around 40% more fuel for the same burn as conventional gas.

For example, if you are running 650cc injectors you will need to jump to to 1000cc injectors as minimum to run the same power and duty cycle on e85

 

ohh but the tunability... if u can get to it easily where ever u are, do it, its great for powertuning , other wise just use 93, or i guess 91 for you blokes in cali, u do have to make the apropriate changes in injectors and tuning, and it can cost as much to run normal fuel because of its lesser MPG rating but, running cooler and faster makes me smile.

 

I've heard the same. Higher octane so you can get crazy tunes on it but everything requires a bit more fuel. My friend was reading up on it pretty heavily for his Turbo II RX7 cause he is moving to Iowa and was going to get it tuned for E85. People are making a lot more power with it compared to their premium gas tunes, but they are upgrading to way bigger injectors.

 

E-85 ethanol is used in engines modified to accept higher concentrations of ethanol. Such flexible-fuel vehicles (FFV) are designed to run on any mixture of gasoline or ethanol with up to 85% ethanol by volume. There are a few major differences between FFVs and non-FFVs. One is the elimination of bare magnesium, aluminum, and rubber parts in the fuel system. Another is that fuel pumps must be capable of operating with electrically conductive ethanol instead of non-conducting dielectric gasoline fuel. Fuel injection control systems have a wider range of pulse widths to inject approximately 40% more fuel. Stainless steel fuel lines, sometimes lined with plastic, and stainless steel fuel tanks in place of terne fuel tanks are used. In some cases, FFVs use acid-neutralizing motor oil. For vehicles with fuel-tank mounted fuel pumps, additional differences to prevent arcing, as well as flame arrestors positioned in the tank's fill pipe, are also sometimes used

If you're looking for higher octane, just buy race gas when going to the track or when you know your going to go out and have fun. Have a tune just for that. That is what we do.

 

Damn it sounds almost worth getting the kpro. Sucks that i will have to invest more into injectors but the price for race fuel and the price for e85? Done deal. I mean gas here is actually close to what pump gas is already so i guess it wouldnt matter but to try something new.
