I know my car (94 1.6) can run 15 degrees timing -with 92 Octane fuel. How much higher can I advance timing and not damage the engine with 50/50 water/methanol injection (SnowPerformance kit) ?

If not, you may actually lose power since methanol has only 60% as many BTUs per pound as gasoline and you're displacing air and fuel with the water. You would have to increase compression ratio to make this a sensible mod.

for all that effort, your butt won't even notice the difference, and like Bruce said, you'll likely lose power.
I think you should spend money on real mods first. like intake, exhaust, header, pulley, or turbo.

He won't notice the loss in power the water makes, either... Plus with metanol he'll be just a tad richer than usual (good). Water injection adds a miniscule amount, far less than gas, and even the volume of gas in the mixture is nothing compared to all the air you pump through the engine.
I say, the big upside is that he can run his 15 degrees of advance on 87 gas from a local Crown station and not have holes in pistons And a clean exhaust system/combustion chamber, too. Water injection alone is not a real power-booster, but still a good thing to have, in my book at least. Less money spent on gasoline/cat converters/plugs/oxygen sensors = more money spent on goodies that make you go fast.

No. Any oxygenate will make a given fuel volume leaner. You have to push more fuel for a given duty cycle to get back to stoichiometry.
Methanol... 2CH3OH + 3 O2 → 2CO2 + 4H2O. Kinda burns by itself in the air, you know. Since it's goode ole alcohol anyway.
