I run a cooling mist pump and snow nozzle. Seems to work really well

is it more a cooling thing or how much performance gains were seen?

I run a cooling mist setup, it works great at keeping the temps down, gonna add some boost juice and see what kinda power we can get out of it soon tho

Dont mean to hijack but I have a brand new stage 3 kit from snow for sale that I bought and never used if someone wants it
Cooling Mist is by far the best you can buy on the open market...
Stay away from water injection if your looking for HP. If your looking to cool your EGT's then its the best thing you can put on your truck...
The more meth you add the less cooling you get out of it.

is cooling mist just for water or can you mix water and meth?

Care to explain that. My truck has proven gains of over a second faster quarter mile times. That was running 50/50 and one nozzle.

of course you CAN make more power with methanol...
it's just much more risky to say...make 50 or 100 or "x" hp with water/meth than by using just diesel fuel & air...
methanol is a fuel.
a 7.3L engine runs by compressing air/boost ~17.5:1 times in the cylinder bore...
If you bring a fuel into the cylinder with the intake air/boost...you, me, no one can control WHEN that fuel (methanol) begins to combust...as that is going to occur whenever the piston moves upward toward TDC creating high heat & pressure.
(diesel fuel) Injector TIMING is the only control mechanism that can be used to determine WHEN the fuel should be entering the cylinder...and since (with methanol coming into the cyl with the air)...you will have a pressure spike in the cylinder...trying to force the piston back down its' bore...PRIOR to the fuel injector ever firing.
The higher %'s of methanol...the power can be made...but at higher risk to engine damage...since the combustion event timing is out of any ones hands.
We run zero methanol in any of our trucks, simply distilled water to act as a 'chemical intercooling'...the evaporative affect of the injected water will cause the boost charge to become more dense (more oxygen molecules for a given volume)..so water alone can add some power...but not much in our experience.
I don't think Joe was arguing that power CAN be made with methanol...
some guys blow their chit up at 400hp with propane, while others make 650+ on diesel/air for this same exact reason.
And the swamps crew has tried it all from one extreme to the other. I would only run water as well.
Another thing it does is act like a cheap DPF without the negatives in that it ends up creating a cleaner burn. Its used slightly differently but same idea in industrial engines as a form of emissions control. Point is it can help control smoke. Just another positive point.

So just out of curiosity can you inject small amounts of straight water into the engine at cruising speed without boost or is boost absolutely necessary to actually evaporate the water within the intake tract?? Thinking about adding it seeing as how my egts get out of control fast but making two stages one with a small nozzle and one with a high pressure large nozzle
Depending on EGT level and level of atomization of the water spray. You do not want to snuff out the combustion flame which you would feel with surge and sputting. I have always know to do it with staged progressive setups is 1 stage turn on point is the egt level you have at hwy cruising speed. That's your starting point move it either way along with the pump duty cycle on point. There are guys with more experience than I thought.

I've yet to see a dyno sheet that showed an increase on water alone. I've seen decrease of a few HP though.
I'd definitely run it as a EGT inhibitor, but I wouldn't expect power out of it unless I was peggin my EGT gauge without it.

I'm a big advocate for the snow mpg max system. I ran it agressively on my insanity tuned '97 power stroke powered '84 bronco. pretty low powered truck in that form, especially with 40's, but at any rate it picked up noticeable power, and about 150* egt drop on straight water, and minimal egt drop on 50/50 methanol, but significant (relatively mind you on only a chipped obs) power gain. I could crest a specific hill on the freeway at 95 mph max effort with the juice, and only 80 without. Take that for what it's worth. I also went through the 7 gallon tank every 150 miles or so too.
