E85 and n20? Anybody here?
E85 and n20? Anybody here? Well I know n2o and alky work well together but I never liked the problems associated with alcohol like having to purge your fuel system. Now with E85 they have 15%gasoline and not as many problems as straigh methanol so I am thinking about swapping to E85 for my n2o enrichment fuel cell or maybe run the engine on E85. I am running a 10 second naturally aspirated 383 and would like to spray 200-250HP n20 on top of that. Anybody try this yet b/c I am definately going to try to run on pump fuel as much as possible and E85 is just starting to get around here. Right now I have 42# injectors and a Fast DFI setup so I know I will have to go up on my fuel pressure and or injectors to run it on motor but for n2o just change up the fuel jets? LMK Thanks
I think you'll find a lot of things that cause E85 to be less than optimal for that setup:
Methanol corrodes aluminum pretty quick, so you'd probably want your intake ports annodized. Also need to make sure you have the right type of seals, as it will degrade certain types.
E85 is less efficient than regular gasoline (higher octane but lower BTU (chemical energy) per volume) so you need to pump in nearly 40% more volume to get your AFR right (E85 stoichiometric fuel ratio is closer to 9.7:1)

i ran E85 and N2O for a while last year(small 150 shot)...right now i am on gasoline due to an upcoming road trip beyond the range and availability of E85 outside of my area...
will be back on it soon enough...
anyhoo,i tuned it to the same AFR as i ran on gasoline,motor or spray...

Methanol is corrosive. But please e-85 is ETHANOL not METHANOL!!!
Ethanol will not corrode your fuel system or any al. part. Please do not spread false info on ethanol, it's helped corn price greatly and my family is actaully making a buck for once
From 1888pressrelease.com:
FACT: Yes ethanol is corrosive, but not very much. Gasoline is corrosive too. Ethanol is biodegradable in water. So it has a tendency to contain and attract water. It is not the corrosive properties of ethanol that can cause damage to your vehicle; it is the water which can rust a vehicle’s fuel system from the inside out. Today’s vehicles (since mid 1980s) have fuel systems which are made to withstand corrosive motor fuels and rust from water. Also today’s distilling processes are superior to way back when. We now have better techniques for drying out ethanol or reducing the water content.
One other potential consideration in choosing ethanol for fuel:
Making fuel from the food supply can deplete the soil and increases the price of food. While it is easy to replace nitrates with fertilizer so plants will grow, it does not replace the minerals in the soil. Because of this, conventionally grown grains and vegetables these days have a mere fraction of the mineral and vitamin nutrients they did 30 years ago. For this reason, I don't personally support ethanol from corn or other foods. However, I heartily support the ethanol from trash technologies that are emerging.

A couple things here - first to the OP. E85 will be fine to run No2 on - but I would highly suggest getting your car tuned for it. Keep it on the dyno and tune for the spray. I would not trust the "increase your injectors 30%" theory thrown out there in other threads. Best of luck and enjoy.

I have been running my 2001 Z06 on E85 for a couple years now (ever since premium gas was about $5 a gallon around here) and I converted my friend's 2002 Z06 to E85 about a year and a half ago. He sprays his LS6 with a wet 150 shot and has had alot of success. I am working on my N20 setup, and the additional fuel required with E85 is nothing to sneeze at, when using N20 and E85 together. My friend has a sweet fuel rail setup, but otherwise his fuel system is stock. My fuel system is bone stock and I am realizing that I need to modify my setup to get the proper amount of fuel to the engine. We both get our fuel off the rails, and we both have the 42lb "green top" injectors.
Thanks guys, I will be running a Fast DFI with a wideband so I will be monitoring AFR closely before I really stand on it. My take was start off on pumpgas in tank, C12 in the standalone and just spray water/methanol to keep it from detonating on high doses of n2o. Now I will run the engine on E85 then spray n20/E85 or C12 whichever works better anybody tried this?
