Can I run E-85

[kinger]

In my nitrous set up I have a seperate fuel tank that normally keeps race fuel available for my nitrous system. Its a complete independant system that has its own alumn tank, rubber lines, fuel pump, and enters the engine AFTER the carbs directly into the intake ports of the engine.

My question is instead of running 118 octane in that little tank can I run e-85 instead? I know it has the equivalent of over 100+ octane rating so I'm thinking I would get the same effects as the race fuel at 1/3 the price plus accessibility is a LOT easier for me. I'm going to lower my shot to 40hp this year to help prolong the bottle because the 80 is just too stupid fast for me. So I could probably get by on just keeping premium fuel in the little tank and some in the main tank on the days I want to run the nitrous, however I just got to thinking about the E-85 and that it would probably provide better protection against detonation. My question is will it hurt anything? Can't be worse then when I run race fuel through the engine when on the nitrous right?

E-85 is the sh**. I two buddies running it in their cars 30 psi on a stock Mitsubishi 2L motors. It loves boost and timing advance. From what we've seen it seems to be just as good as 110 or so race fuel for preventing detonation. It does require 30% more fuel then gasoline. It also does not like starting in cold weather, and this is the only thing holding me back from running straight E-85 in my Apex. Now, for your situation I think it would work great because it wouldn't be your primary fuel source so that wouldn't be a issue. Plus your running a wet shot so it would be easy for you to jet up your nitrous fuel jet.

E-85 has about a 105 octane rating, all you will have to do is UP your Fuel Jets in the NOS system and you will be fine.

This is what I worry about, not sure if my fuel tank or NX fuel pump will take the fuel, from wikopedia:

"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.["

My buddies I mentioned have been running it for over a year in their cars with dual Walbro 255 fuel pumps stock fuel tanks. One of them uses his car as a daily driver to. I think you would be fine.

Kinger......I will get you the information on the new jet for the NX kit next week for running E-85.

Kinger....you need about 20% more fuel for E-85. Check your plugs it might be a little rich. But it should be very close.

Think the fuel system and tank will be ok to use it?

Thanks for getting back to me, this will be MuCH easier.
