50/50 Water/Alcohol

Yes in lives in SC, its the south's E85 mecca.


And OP, dont go meth, go E85 with two maps (E85 and 93). Meth is a PITA, and ive seen a fair share of motors blow from an improperly functioning system that was "supposed" to have built in fail safes. Because s*** happens, and when it does on meth you can kiss your engine good bye.

E85 will get you all of the benefits of meth and then some (actually alot more). If you have any questions on E85 ask away, I also have a FAQ thread on E85 on here somewhere, you can search for that too.

Meth is hardly a pain in the ass, in fact its much easier to work with then E85 by leaps and bounds. But your right in one way, there's not much you can do if it fails and your foot is WOT on that gas pedal. It relies strictly on a 12v signal from a controller to determine when the system is on, not how much pressure is feeding from the pump, so your controller can still switch your timing maps, but your pump may have failed, regardless of how rare that is. One of the biggest causes of premature failure is the pump overheating or being positioned improperly. I use a 3 gallon trunk mount system so my pump never see's ANY heat at all. I have a series of lights that indicate on or off and low fluid level just like a gas tank on my dash right in front of my tach. I get about 4-5 degrees more timing out of running supertech -20 windshield washer fluid for 1.19 a bottle, and it drops my blower temps down from about 180 degrees to about 130 degrees on a 4gph nozzle.

With a 50/50 mix you can get upwards of 110 octane and with 70/30 about 116, however beyond 50% methanol in your mix you need to have extra precautions in place with the tank system because like gas fumes, methanol vapor is also very flammable.

I agree with you aside from the easier part, think of everything you just said that's needed to install and the proper safety precautions. e85 only needs a fuel pump and injectors, and a lot of the time even that isn't needed for lower power apps, it depends on the car. That's much easier, especially when you consider what might happen when meth goes bad. That plus e85 makes much more power than meth.

My only problem with e85 is how much is enough? All e85, or only a part of the tank? And if only a part, how to regulate it to keep the percentage constant...so many factors, but still like the idea

You will need to run all E85 and retune.


The only cars that can play with percentages are newer cars that have a ECU that can appropriately compensate. Most new cars can take about 30% E85 mixed any more and the ECU may run out of the ability to compensate and run lean. The reason people do this is its a easy way to boost power without any modification. But for you, your ECU cannot appropriately compensate for any mix without a tune and therefor you will need to re tune. And if you have to re tune you will want to go 100% E85 to get the maximum benefit.

E85 availability is a much bigger problem to consider

It's available here. There is at least one station in Conway that has it and I'm sure there are a few in surrounding areas. If anything, I could just save a map for pump gas and switch it when the season comes (E85 disappeared last year around Dec-Feb)...

Its worth it on a boosted car. N/A, not so much, but boosted makes a big difference.

ill ask my tuner to set up a e85 tune then and take advantage of the dual tunes on my s300 :thumbs up

Yes it is, however if you live in certain areas of the country its no problem like the OP and myself.

SC is loaded with E85 stations to the point that E85 bleeds into the border areas in NC and GA. Then it starts to become scattered. I have a 93 map as well, because when traveling long distances you cant find E85.

Only issue I would see with E85 is the extra fuel consumption. However, I don't plan to daily it, just weekend warrior so I'll keep considering it. Could someone post the link for the FAQ on CI? I can't seem to find it through the search box...

it almost evens out in the end for cost and consumption. but we dont boost cars for better mileage do we?

Very true Its all about the POWAA lol
