Meth/water injection
Is anyone running a meth/water system on there N/A or
naturaly asperated motor? Is there the 10-15% HP claim? How are you activating the pressure switch? They are saying that the 50/50 mix of methanol and water is equal to 116 octane and 50-200deg. cooler intake air. It may not work as well on N/A as Turbo or blower combo but is it worth say 40hp on a 425hp motor is what Im wondering.

I would say no unless your engine requires a higher octane.
If it needs 87 you don't get more power putting in 93 do you?
If you have a built motor and you can take advantage of the higher octance, and advance the timing, then yes, and it will cool the intake temps.
I will be adding 100% meth to my SC C5Z soon.
You will have to get it tuned for it as well.

I call BS also. 116 octane? Even if that were true (I really doubt it), so what? Are you suffering from knock now? All that octane does is prevent premature detonation. 200 degree cooler intake air? It's going to be 100 degrees below zero? Huh?

Ran a syetem on the ZR1 came on at 3/4 throttle it really helped cool the intake charge down so it didnt ping. PIck up a bumch of power, no.
Use 50/50 windshield washer fluid/water was told it equates to 5% dont know how accurate that is.
The methanol is really for boosted apps. I did try using some methanol and the car got real slow...and real lean! Car has to be tuned for it. Would not recommend using actual meth for NA waste of time.
More or less water injection (for NA)> May run one on the new motor in case Im stuck somewhere and cant get great gas. Get a decent size tank, it will run a ww washer reservoir dry quick if youre driving it hard.

I had to pull fuel out of the rpm based pe tables since id watch my wideband afr sink (go below 10:1) as soon as the meth hit.

My motor runs better with higher octane so I thought it would be cheaper than high octane fuel all the time and if I got a 5% hp increase then that would be a bonus. Hell you can get a base system for a couple hundred bucks so if there is 5% gain then it would be worth it. OK I was just checking into it because I have an 11:1 CR and thought I could get some benefit. I defenatly wouldn't run it on a stock motor I realize that much but I am running a 383ci. 425+ hp and thought it would be worth askin Thanks guys!

You wont see that kind of gain. If you suspect you have a problem with pinging then its a good thing and will help save your motor and dont have to worry about pulling as much timing out.
Big gains are in forced induction applications. Every bit helps though.

Snow Performance is supposed to make the best Methanol Alcohol Injection Kits.
You are supposed to use their premix bug juice too.
Standard windshield washer fluid does not have a consistent Methanol Alcohol mix.
The guys that use Snow Performance Meth injection kits love them from what I have been told.
Even on normally aspirated applications with 13.0 : 1 static compression ratio on 93 octane pump gas.
Snow Performance Meth Inj. Kits are expensive.
But if it works it will save you $$ in the long run & deliver some extra HP.

I really cannot answer your question on NA, but a meth system did permit me to get rid of all the intercooler hardware and plumbing from my Procharger. You do really need to run 100% meth to get the maximum cooling effect. Don't forget you need a custom tune to get the max out of it.
