Has anyone used Methanol/Water Injection for N/A carbureted?

[565bbchevy]

I'm looking into possibly running a methanol/water injection set up on my car that is carbureted and has a Zex nitrous system. I'm considering 2 brands Snow Performance and Alcohol Inj Systems.
And I want to use dual nozzles and an adjustable controller and I also want to deal with a company that will be around in years to come if I need service parts.
I have limited room so I would run the tank and pump in my trunk and run the line up to the front and up to the hood and I will mount the nozzles to my air pan aiming down to my front throttle bores.
I've been told by both companies this will work fine and the vacuum will actually pull the mist in.
Does anybody have any experience/suggestions about using this.

I'd like to know about this as well...i've been curious about this for awhile now and thinking about trying it

Re: Has anyone used Methanol/Water Injection for N/A carbure

it will definitely help out with high compression or nitrous like you're intending. the nozzles in the hood would work great as long as they're inside the filter element. just wire the pump to come on w/ the nitrous solenoids. the methanol will act as using a larger fuel jet as well (richer A/F ratio). this does mean that your jet chart will no longer be accurate, and depending on how much methanol you use will determine how you have to size the fuel jet. definitely dead head the fuel pressure regulator for the fuel solenoid if you're going to have the pump mounted in the back of the car. the "creep" is a good thing, especially in this situation because you'll most likely get a lean spike on the initial hit, (from the methanol making its way up to the front, has a lot longer to go) which would be countered by the fuel pressure creep. by the time the fuel pressure drops to where it's supposed to be, the methanol will be in full force. this should definitely go on a chassis dyno to get sorted out correctly. i guess one way around the "waiting around" for the methanol to come up front would be to use a bump button and purge the nitrous and methanol into the engine at the same time. this would probably be a better thing anyway because the nitrous/methanol will cool the intake and cyl. head ports off too before you run the car. ultimately every set up is different and this may or may not work for you. we did my friends car with the bump button setup, and it worked out pretty well.

I have never ran it on a NA motor but its been the single best upgrade I ever made to my GN. FWIW This guy is sharp helpful and enjoys a great reputation for many years in the Buick GN community. Great quality stuff and support. Stand up guy. He also posts on the methanol sections at www.turbobuicks.com and turbobuick.com and I am sure other places. You might at least pick his brain. Here is their site. http://www.alkycontrol.com/

Well, what I want to do is use a progressive controller for all driving conditions based off manifold vacuum as far the nitrous that has limited usage since this is a street car, the nozzles would be mounted to the air pan in the picture with a bracket that I would make, they would be aiming down into the carb, the exact location would be based on the manufacturers recommendations.What I am looking for is anyone using the injection in a N/A carbed street driven set up. If it were a track only set up then I would tune the injection specifically for the nitrous. Thanks

There was a good article in the Aug 2011 issue of Popular Hot Rodding on Methanol Injection on a N/A vehicle. The car they are using it on is not a GM but one from the blue oval camp. Heres a link to the article http://www.popularhotrodding.com/tech/1 ... ewall.html

Im no expert on this but your placement is no issue. Thats a smokey yunick trick. He used to put the bottle just anywhere under the hood and it would find its way into the carb. The nitrous i mean.

My nitrous is already set up it's a Zex perimeter plate system but that would be a stealth set up.

I would highly recomend not getting an AIS kit. Not going to get into a bunch of bs slander but they got my money and i got a paperweight for a turbo after doing what rodney told me to run 🙁 Then i talked to snow and devilsown and both of them gave me simlar advice which was on the other side of the fence . Both said no meth threw the turbo and he told me to do it.

If I decide to do it most likely it will be a Snow for one thing I can't fit the tank for AIS anywhere in my trunk.
Plus I've been emailing Snow about my injector mounting options.And they will give me a discount if deal direct.
