The Snow Performance SNO-530 Stage 3 Boost Cooler Water-Meth Injection Kit is specially engineered to help get more mileage out of your 2001-2018 GM 6.6L Duramax.  By reducing air temperatures over 200°F, water-methanol injection helps improve mileage by aiding your engine burn the fuel more completely in the combustion chamber. This water-methanol injection kit contains the VC-50 controller (52mm gauge) that features a 7 color (Red, White, Orange, Yellow, Purple, Green, Blue) OLED screen that you can tailor to your style while displaying boost, percentage of injection, secondary nozzle activation, prime button and 4 fault codes (Pump Failure/Solenoid Failure/Clogged Line/Broken Line) that will alert you to any failures in the system.

The Snow Performance SNO-520 Stage 3 Boost Cooler Water-Meth Injection Kit utilizes the VC-50 controller to regulate the two nozzles that inject the water-methanol accurately into the engine based off of boost pressure. Water-meth that is injected in relation to boost permits precise delivery of the water meth while providing added performance and lower EGTs across the entire RPM range. Start and full throttle injection stages can also be controlled to adjust the injection delivery to where it’s most beneficial in the RPM range. Included in this water-meth kit is a 7-gallon reservoir, mounting hardware, anodized aluminum straps, 300 PSI Ultra High Output pump, fittings, and either red nylon tubing with quick connects or -4AN braided stainless-steel line.

What are the benefits of Water-Methanol injection?
Great HP per dollar value.
Decreases of 250 ° F are common using a 50/50% Water-Methanol mix.
More Horsepower while lowering EGTs makes this a great addition for hauling the heaviest loads.

Is this technology new with Turbo Diesels?
No. Water-methanol injection has been used extensively for years in as a common means of cooling the intake charge and reducing exhaust gas temps in high performance truck/tractor pullers. Also, truckers have used water injection for years to increase fuel mileage and lower EGTs. 

Why methanol?
Methanol’s high latent heat of vaporization makes it an excellent air charge cooler which means a denser mixture and more horsepower. It is extremely toxic and should be handled with rubber gloves in well ventilated areas only. Care should be taken to avoid skin contact.

Where can I purchase Methanol?
Methanol can generally be purchased where racing fuels are sold. Also, most gas line dryers like "Heat" are simply Methanol. Suppliers of industrial chemicals can also supply Methanol usually at a higher price than fuel suppliers. If all else fails, most windshield washer fluids are up to 40% Methanol and 58% water.

Can I use windshield washer fluid?
Although most contain some glycol and detergent, most windshield washer fluids are up to 50% alcohol (methanol, ethanol, isopropanol) and make an excellent Boost Cooler. Try to find one that indicates "contains methanol".

What ratio of Water-Methanol is recommended?
A 50/50 ratio is recommended. Diesel applications where water conditions the combustion of the methanol so combustion timing isn't affected.

Will water-methanol harm my engine?
In theory, at recommended quantities, most of the mixture is evaporated before it hits the combustion chamber. Also, injection only takes place at high boost levels minimizing cylinder wash concerns. Engines that have been torn down after two years of water/methanol usage have shown no wear issues only clean combustion chambers. 

Why is Water-Methanol injection so effective on Diesels?
Unlike gasoline engines, the power in a turbo diesel is largely a function of fuel. The problem with continually adding fuel is that you reach a point where the exhaust gas temperatures become prohibitive (over 1500 degrees F). A 50/50% Methanol/Water mix will decrease EGT's approximately 250°F while increasing power 70-100HP.
