You typical windshield washer fluid is around 33% methanol. The poison labels are on there so you don't injest it. Just a little FYI.

 

Methanol at the track out here is $2.50 a gallon. Mixing it with distilled water makes it even cheaper/gallon, I wouldn't use the tank that comes from Snow, it's too small and will require constant monitoring/refilling. I would take the route that BigBri did with his kit if i were you.

In my Cobra I use the factory WW tank, as it's twice as large as the snow tank and is very stealthy. Since W/W fluid is ~25-45% methanol(depending on the brand), I don't hesitate to also use it to clean the windshield too.

 

I mostlikely will get a bigger tank eventually. Keep in mind I only push the car past 5 psi at the track, I baby it on the streets so I don't think I'll need to refill as often...time will tell. Changing to a bigger tank won't be hard since I will mount it in the trunk anyway.

I checked for methanol prices online and there are about $4 a gallon

 

when I read the label it freaked me out a bit...causes, blindness, causes death, never get in contact with paint on car (hence no good as a window washer)...
I figured better safe than sorry

 

I just ordered a longer feed line from Snow, that will solve the line length problem

 

I fill it up about every three months.....I floor it 3 or 4 times a day...so I use a lot...it I babied it a lot or didn't daily drive my car I would say every 4 months...It only shoots at 10lbs of boost and above...

 

If you wanna use the OEM Washer tank (which also provdes a low water dash alarm) you really only need to mount the pump below the mid to high water level and add a simple inline check valve. First time the pump primes just make sure the water is topped off.

In Cali I've run simple water no methanol for years on other apps. It still does a KA job of detonation suppression. I only add Methanol in the rare winter occasions when there is a freeze warning.

 

this article talks about that check valve:

Sorry if this is kind of getting off what everyone is talking about, but im going to be using utec and would also like to use it to control water/methenol injection. Can anyone make some suggestions on the best kit to go with ?

 

Awesome!

 

+1 Seems like we can eliminate the electronics module that comes with most kits since the UTEC should take that task.

 

I just got my Water/Methanol Injection kit and am going to install it this coming weekend. I took off the bumper this past weekend and good luck in finding space in there. I plan on doing what Bigbri did, mount it in the spare tire area. Only difference is I am going to mount the tanks (2) in the spare tire area too.
I am going to run the water line under the car in some protective housing. I really don't like the thought of a high pressure water/methanal line running on the inside of my car.
I am going to mount one injector (high boost - 8.5-9psi - high water flow) 3" after the Mass Air sensor, and one injector (low boost 4-5psi - low water flow) 3" before the throttal body.
I also have flow switches for each injector to ensure I have water going in when I need it. This also act as a plug nozzle detector.
I will have a on/off switch, 6 LED's (power, Injector 1 on, Injector 2 on, Tank low level, 2 - flow switches) mounted on the inside of the car.

Some design consideration that I am implementing:
- Water filter
- no splices in hose
- Pump lower than low level in tank
- shortest distance from tank to pump
- Use the same type of fuse as found in the car
- On/Off switch
- Clog/flow dectors for nozzles
- Mount boost switches (for water injection) easy to access so you can change pressue fast
- Low level switch on tank
- Wires that can handle oil/gas and high temperature
- Water injectors to spray in direction of air flow
- Consider how to fill tank once mounted
- Keep hose and wires away from heat sources

If anyone can think of anything else I need to consider let me know.

 

By eliminating that it should eliminate quiet a bit of $$$ from the price of the kit. Im all about that.
