either way I am going e85 and meth. overkill Id say. going to run the tune on kill and keep an eye on things with the wideband.

 

im thinking about using
33% water
33% meth
33% acetone. i think it will pick up more than just 50/50

 

2-#15 nozzles. 100% meth. I would never mix it with water.

 

My setup is 2-12gph nozzles and 100% VP M1 Methanol.

 

My wife was going through 3 gallons a week on 558 rwhp of 50/50

 

Pure Meth here as well.

 

Informative thread.

 

To answer a few questions. E85 and methanol are different. E85 is 85% ethanol and 15% gas. Ethanol cools well, and is very detonation resistant. However the big reason i like ethanol is it isn't nearly as corrosive as methanol. Seems like if you run meth that crap will sit and eat up everything metal it touches and always plugs up.

However running on straight methanol will make more power than ethanol, but meth takes about twice as much fuel as gas. Ethanol only needs about 35% more.

Also e85 does vary in the pump cause they add more gas during the winter. But the difference only makes about half a point on the a/f which i bet most peoples tunes are off by that much already, so it isn't a big deal. The big thing with e85 is to make sure it is fresh because it will absorb moisture.

 

Do you have any proof of that? That's the first I have ever heard methanol being corrosive to metal. The only issue I have heard of in that manner is the coating they put on blower rotors but never the metal itself.

 

Thats a serious drug addiction problem there! I run 100% meth and I usually go through 7 gallons a year (5000 miles).

 

ive never heard of methanol being.corrosive. i have heard of ethanol being corrosive.

 

Methanol will attack aluminum. The higher the temp the quicker it corrodes.

 

Methanol is very corrosive. We run it in 2 stroked carb applications. If you don't purge the motor with gas, then the methanol will sit in the carb and eat away at it. Plus since it holds moisture in it very well. So in the 2 strokes with gas being in the crank the methanol will take out the bearings and cylinders by causing them to rust from the moisture.

Not only that but running it through fuel injectors will eat them up quick. If left sitting in there it will corrode away the parts inside the injector, eat up the seals etc... Methanol is some nasty crap. Ethanol on the other hand I don't have nearly as many issues. I can let it sit over winter in a motor then fire it up with out any issues. Do that with methanol and you will be replacing most parts it touches.

 

hmmm weird. good thing it only sprays while is under boost and it all gets burnt up. im still.stayin w/ met and 93. e85 is a PITA for me.
