boost and pump gas
Yeah some times I speak before I think. That's the beauty of the edit button (for most people anyways) lol
I agree with a lot of what you say but not all of it. But that's how it goes. My experience with these motors and many other turbo applications lean me towards my suggestions regardless what other loud mouth internet experts think.
Take it for what it's worth but I think enough people with real world experience have proven my point in this thread so I'll leave it at that.

It's just my thought and personal experience. Your results may vary.
But honestly, when it's all said and done, it's pretty tough to beat the price of Boost juice. Unless your spraying a 1000hp motor with tons of it doing mile events, a gallon will last quite a bit of time.
Here's some info on freezing point and water/meth mixtures:
Methanol (METHYL ALCOHOL) Conc.
Vol.% ---Freezing Point,F ---Flash Point,F
0----------32f--------No Flash
13---------20f ----------130f
24---------0f -----------110f
35--------(-15f)---------95f
46 -------(-40f)---------85f
56--------(-65f)---------75f
66--------(-95f)---------70f
75--------(-115f)--------60f
83--------(-125f)--------55f
92--------(-130f)--------55f
100-------(-144f)--------55f
So if you pick up windshield washer fluid that says it's -30f freezing point, it's roughly 40% methanol/60% water. Which is fine, if you make certain your injection rate/percentage is appropriate because you can cool the combustion process too much and hurt performance.
So look for the -40f windshield washer fluid and you should be ok.

You should never agree with people 100%, because then you become just a sheep and not a free-thinker, and will never learn on your own. I've said it a couple times that he could be fine at 550hp, but do you think he's going to set the boost on the dyno when he fires up the car? No, he's going to set the boost at 6, 8, 10+ psi and then dyno the car. So he could be making upwards of 600-650hp, who knows. I look at meth/water injection as an octane booster as much as a coolant for the air and combustion temps.
It's just my thought and personal experience. Your results may vary.
You can run windshield washer fluid just make sure you get the one without any additives like soaps. Avoid the Rain-X because they add a bunch of different chemicals. Also, you'll need to add some extra methanol in the form of Heet at local parts stores. I don't have it here, but I have chart that lists the freezing point of different mixture ratios, so if it's listed as -20, or -30, that translates to a specific amount of methanol to water ratio. I'll try and find the table and list it here for reference.

Amen to the sheep comment. Seems like quite a few people take that route now a days
especially on this website. Air temp coolant
I like that 700+rwhp, 15+psi, 93 octane only, no meth. Low timing and rich a/f keep it safe with aggressive iat retard table. It would definitely pickup with meth, but I don't want another component that can fail.....when a fuel pump fails you have NO fuel which is fine, when the meth pump fails you lean out and go boom since most seem to tune with meth on instead of tuning without it and then adding for a cushion and decreased iat.
This may take the subject off the rails, but I seen a recent build thread where a guy was not using an intercooler, just spraying meth. Considering a lot of the post has been on IAT's, I figured I would see on how this weighs in.. I'm about to start my first build and it looks so much more simple without the use of an intercooler

The guy I bought my turbos from was running a stock LQ4 with no intercooler. I don't remember if he was running meth or not. Also i'm pretty sure it was strictly a racecar. I would shoot him a PM (71chevy) and ask how it worked for him he is a super friendly guy.
