Post subject:  e-85 and turbocharching
what are some of the pros and cons. I know e 85 is supposed to burn cooler, i think but, you have to advance your timing because it ignites earlier. how would this effect a turbo, or would it at all. I have a 85 midnight blue stepside and a 63 white dart gt. All this turbo talk is making me crazy. I have to have one someday. I was originally going to try to set my sixes up on e 85 just to go a little green and it supposedly has a octane rating of 105 which might help. Seeing the power that a turbo charger can give a six makes me very envious. I always had the idea in the back of my head but i didnt realize there was so many people out there turbocharging these things. :roll: :shock: :D

well i wouldnt even consider it, since the CR needs to be high for E85 with its 105 octane rating. it might be possible to still do it but the turbo would be not adding much, from my understanding on a high CR motor.

E85 does burn at a lower temp then gasoline, so the engine will run cooler as well.

i think with E85 to he slant six would be a good mate. as stated about the /6 liking higher CR's. i guess the question is how high a CR can you go on the /6 for this type of setup. the high CR would also allow you to run race fuel with its 118 octane rating as well. If you wanted to you could add some race fuel mixed with the E85 for mix. i do recall that you have to be carefull with the octane rating though. as one article i was reading showed a improvement in HP when going to 100ish octance from 118 race fuel. not sure how exactly that works but the way they described it, it made sense.

E85 doesn't get much love on this site so I am just going to point you in the direction that will give you the most usefull info.

www.theturboforums.com & www.e85forum.com

There are a ton of success stories with using E85 + boost to make big power and then there are the few that are tuning their vehicles for ecomony. Those guys are few and far between since it is a bunch of work and some exotic parts to make the switch just to get a couple extra mpg's.

You can also use this site's search feature to find your answers. I have pretty much asked the same questions a year or so ago.

Where are you located in MN??

I also remember that I read something that e 85 is 80 percent ethanol and 20 percent petroleum, but they said this mixture isnt always the same so its not a very stable fuel. That would probably affect fine tuning alot. thanks for the replies.

Gaining power from going to 118 from 100 is pure horseshyt unless the motor had too much compression to run on 100 anyway. The fuel itself does not make power, it allows higher compression and timing which is what makes more power.

I know from helping Mike Lopez with his dyno that you want to set your motor up to run the least amount of octane and timing you can (for your particular combo). It will make more power that way, and live longer.

A turbo Slant on E-85 should be a good combination. All you need to do is learn how to control the fuel/ignition systems to keep it from eating itself.

Contrary to popular belief, a turbo is not a "bolt on and fly" modification. Of all the turbo projects I've seen and/or been involved with, I have seen 1 that runs well for every 10 built. Just like using nitrous or a supercharger, there is a learning curve.

The content fluctuates with the seasons. Right now it is E70, by summer you will typically get E83. The reason is that it is Ethonal is hard to light in cold temps.
My brother races a E85 fueled Mustang and we started buying E98 (as pure as possible) and blending our own to get consistant mixtures.

sounds like you have a very good idea about helping people with there rides. I would much rather be involved in the resto than just paying someone else to do the work. where is comfrey located, Ill have to look you up on map quest.

It works on yours, they say you have to put it in your principal box but is there something you have to put in front or behind it to make it a link.

You got that backwards, his statment was going from 118 to 100. This infact can give power if the engine is not in need of the higher octain fuel. You only need what the engine needs and no more. Burn rate and such are some of the reasons for this.

Trust me, E85 plus boost on almost any motor is great combo

Here is an example of what i have done so far with e85

122 cubic inch 4 cylinder 8.5-1 compression and big turbo at 42psi boost

733 horsepower at the wheels ( about 850 horsepower at the crank )

no detonation, able to run better timing than 116 octane race gas ( 23 degrees ) and more hp than race gas mainly due to the oxygen content of the fuel

Currently building an E85 turbo slant 6 for my 1974 dodge dart, shooting for 350-400 whp on the stock bottom end.

I didn´t read the entire thread but thought I´d give my opinion. I´ve done quite a few cars on the dyno, converting carb to injection, turbo-charging etc. Except some cold-start issues (gets -30c here in the winter) I have only good experience with E85. There´s not much hp to be made on a stock engine, but it will allow for quite a lot of boost on stock cr ratio and timing.
