Do boost coolers (meth/water injections) have ANY long term side effects?

I guess you could try running 89 octane w/ the W-M injection at your current boost level (or maybe start off much lower to be safe) and see if you could get away with cheaper fillups. But that would make running out of fluid in the middle of nowhere more dangerous.
Jason, I hadn't thought that finding -20 or -30 F washer fluid would be a problem, but you're right its probably not needed in temperate places. In that case mixing your own from commercially available meth or denatured alcohol is a pretty reasonable option. A gallon of self mixed 50:50 should come to about $1.50 if you do some careful shopping.

so- if i'm running at the max i want to run on **** gas (91 octane) and i want to up the boost a bit (3 or 4 psi to say........18, 19, maybe lower), then adding water/methanol injection would allow me to do that so long as i keep my fluid level up?
so it's kind of a "boost" to the boost?
but once i run out of methanol/water i need to turn it back to a safe level for that octane?
so it's essentially an octane booster that you use on and off?

The guys who race turbocharged buick grand nationals swear by running 100% methonal. the main guy on their board is "razor" here is his link. www.alkycontrol.com
Here's the other one from their board.

These guys run 28lbs on pump gas and swear it runs better with alky than race gas.
They've been doing it for years.
That's my plan anyway once I get a stage 3 installed.

[QUOTE=95Juan]So- what happens if you're say- running a chipset for 15 psi.
and you're making a decent amount of HP.
but then you keep the same boost level, but add water/methanol (or other type) of injection?
would you see any increase?
You would notice an increase most likely if before hand the knock sensors were causing you to get some timing pulled... Now with the increased knock protection, you get some timing back.
O.T
Get your corner lenses painted like mine! ha, it would look awesome

those that have big or external freezers can have your washer fluid bottles in there and can get very cold with out freezing.
The benifts would obvioulsy drop as the tank got hot, UNLESS, you use a small cooler as your resevoir and have it located in the hatch with a SS line running to the front.

Not correct. Many, including a recent thread noted major gains just from the much cooler charge air. Same boost, timing ,etc. Just cooler air.
Cooler air = HP

So normal driving runs up to your current boost levels and no H2O injection. If you "feel the need" you flip the switch and get a couple extra pounds of boost with the H2O injection enabled.
