I was curious as to what the perks were for E85 over meth injection. What is the cost of each conversion and real world performance. I was talking to my friend today that is a mechanic and he was saying e85 will give more horsepower as opposed to meth injection but I was wondering what the cost of each conversion was. I don't mind having to plan trips and search for pumps that offer e85. Would that be best for me?I want more horsepower. Also if I run either must I convert from 60lb injectors to 80's???

I would go E85 everytime. In the midwest you can find it everywhere

E85 > Meth, but they do similar things for your motor. If E is readily available, then E all day long. Much safer IMHO then the Meth Injection. Ive seen a lot of issues with Meth setups and they had nothing to do with install or use. The check valves stick occasionally, pumps stop working etc.. When that happens, bad things can occur! So if you go Meth, just keep an eye on things to be safe!

You should only need to change injectors to run the E, everything else will be OK.

both good... but i like meth.... if you dont mind having to stop at a gas station almost twice as much, go with E

i wish it was all over the midwest i would be runing it

E85 without question, meth doesn't compare.

If people are getting that much worse mileage they need a new tune. I get 21-22mpg in town this year which is down from 24-25 on gas. Seems like the biggest mistake people make is not adding timing in the cruising range.

Well I guess in the very mid midwest its all over

Bingo! I picked up a lot of mileage adjusting the cruise timing and the cam timing in the same areas.

The car accelerates at partial throttle so much easier as well it seems, and smoothing the crap out of it helps as well. I has no cam adjustment tables though lol

How much is a E85 setup compared to meth injection setup cost wise?? And where is the best place to buy from?

E85, you swap injectors and fill the car up with different gas. Meth has a system to install. Both require custom tuning tho!

Woah, what lb injectors I have 60's right now. Also don't you have to hafve a different fuel pump? I didn't think it was that simple as injectors and a different tune. I though yout had to get a new pump and some other mods as well??[

AjSS

Injectors depends on what the plans are for the car, in most cases, 80's do just fine, the only other thing you would need is a tune.

newssowner

So I just need 80 lb injectors to run e85? as well as a tune? I don't need a special fuel pump or anything of that sort?

AjSS

Depends what your setup is. Are you stock supercharger, TVS, or turbo? If you are pushing a lot of air (smaller than stock TVS pulley, or turbo) it would be a good idea to have a fuel pump rewire, but the stock pump can handle it.

WSFrazier

As they all said...

If you are on the M62, just 80lb injectors should be enough.

Any other power adder, like TVS, Turbo, or Nitrous, you will need to go with a fuel system upgrade. Something such as ZZP BRFS or OTTP Return Kit. Both use a 1:1 adjustable regulator.

If your car is a 2005, you will most likely need a fuel pump upgrade regardless. But a Walbro can be dropped in fairly easily and cheaply.

Ive run a few cars with the M62 on 80's and changed nothing else (hardware wise) to run E. On the TVS, you will likely need to goto 1K's and may or may not need to address the pump. As everyone said, a lot depends on the setup.

newssowner

Right now I am running a tvs, 60lb injectors, stage 3 heat exchanger. Other mods are ingalls stiffy and solid trans mounts. I threw down 275 on just that setup.

WSFrazier

You will need more than 80# injectors. Most will tell you just to get 1k#, but you are better off changing the fuel system and sticking with the 79#/80# injectors.

newssowner

So by changing the fuel system that would require the 80's and a return style with the new fuel pump or what?? 1k# injectors seem like overkill. I would hope to stay with 80's if possible.

I asked this question in another tread but no body came up with a complete answer.

If you use 100% METH and bigger nozzles, would this lead you to have more hp potential? MOST PEOPLE are using mixture of 50/50 water-meth.

I mean... if the goal is to raise the overall octane level, why not throwing 100% meth??? I will never understand that. And ZZP, one time, came in this forum and tried to debate the fact that a mixture of 50/50 water-meth is not the way to go to make more horsepower.

See... most people using E85 are experiencing amazing hp gains. Why? According to my understanding this is because of the final octane level.

I don't have ethanol gas stations here so I would like to imitate the most possible E85 with meth injection. The only way I think this can be possible is by using a bigger nozzle with 100% meth. I don't care at all about having less cooling because of no water, I don't care at all. I have already LOW IAT2 with all my other cooling mods.

I hope to have complete answers and that will be able to come down with a good formula once for all for this meth injection subject!

Here is a tread I found out by doing a search on google:

Just curious.. 100% methanol - Devilsown Methanol Alcohol Water Injection

Very interesting. I'm gonna put a quote here from that tread:

I've read that some people don't use 100% because they are afraid of the methanol flammability. But what if you put your tank in the trunk?

I really want to imitate the most E85 with meth injection, this is the only way I can do it here!

Lol twice as much I lost Less than two mpg..

Erick161

would def do E-85 if available. For me, the closest is like 5hrs away. Sucks. so meth is my only option.
