Snow Performance Water/Methonal Injection for race and tow vehicles

Water-methanol injection has been in use since the 1930’s as a way to extract as much power as safely possible from internal combustion engines. It gained widespread use in fighter and bomber aircraft during WWII as a way to extract great amounts of horsepower for takeoff and dog fighting. While the physics are the same today, modern technology has allowed greater power increases and better performance while using even less fluid. You could run one system on a turbo diesel tow vehicle and another system on a race vehicle – getting benefits of performance and reliability on both.

How do we get great increases in power on a gasoline engine? Through greatly reduced inlet air temperatures, condensed air charges, and suppressed detonation. Either straight water, or a water/methanol mix, is injected in a superfine mist which starts to evaporate once it’s introduced into the intake. This evaporation acts as a cooling process – the same as if you get out of a swimming pool on a breezy day and feel chilled. Typically a 50-150° F intake temperature drop is the result. Cooling the inlet air that much also condenses the air charge, which gets more molecules of oxygen into the combustion chamber. Inside the combustion chamber, the methanol acts as a super-high octane fuel (as much as 120-130 depending on the measurement) to help suppress detonation, and theremaining water, being impossible to “flash ignite”, has an almost infinite octane rating and absorbs the peak heat and pressure of combustion. During the combustion process the water turns to steam, safely increasing cylinder pressure after TDC during the power stroke thereby increasing torque output. Suppressing detonation (typically a 20-23 point octane increase over pump gas) allows for more ignition timing, higher boost levels, higher compression ratios, and a leaner air-fuel ratio to make more power while being safe from detonation compared to what pump gas can support. Power improvements are typically in the 5-10% range for naturally aspirated engines and 10-20% for forced induction engines, depending on the tune.
For diesel engines, there are even greater benefits. Water/methanol injection provides more power, reduced exhaust gas temperatures, and better mileage, while being the safest way to add power to a diesel. We are still cooling and condensing the intake air charge which again creates a denser air charge increasing the amount of oxygen getting into the combustion chamber. This is why water-methanol injection is often referred to as achemical intercooler. That helps to burn more of the diesel fuel in the combustion chamber. The methanol acts as a catalyst to burn the diesel fuel more completely. The remaining water absorbs the peak heat and pressure of combustion and safely increases cylinder pressure after TDC during the power stroke. This means we get more power, typically 20-30%, from the same amount of diesel fuel being injected because we have harnessed more energy from the fuel in the combustion chamber instead of sending it out the exhaust. With more efficient combustion we get reduced EGTs, typically 200-300° F, and we get better mileage – around 1-2 mpg on a 1 ton truck while towing a typical race trailer.
Snow Performance has several different Boost Cooler™ kits for your race vehicle, depending on the particular engine configuration:
For a naturally aspirated engine running carbureted, mechanical injection, or EFI without a MAF sensor, we use our Stage 2 N/A kit (#20020). This system utilizes a digital progressive controller that injects proportionally according to vacuum. The system also has a minimum RPM injection set point to prevent injecting too soon.
Naturally aspirated EFI motor with a MAF sensor can use our Stage 2 MAF kit (#20011). This system also includes a digital progressive controller that injects proportionally according to the airflow going into the engine. This provides a more accurate way to manage injection.
Forced induction EFI motors with a MAF sensor can also use the Stage 2 MAF kit (#20011). This kit works well with positive displacement superchargers or small, quick spooling turbos. We also have kits that work with the unique GM and Mitsubishi frequency output MAF sensors.
For applications with larger, slow spooling turbos, centrifugal superchargers, or non-EFI positive displacement superchargers, our Stage 2 Boost kit (#20010) is the correct kit to use. It also uses a digital progressive controller that injects according to boost pressure and is also very easy to adjust for maximum performance increase.
Non-progressive kits are also available.
Options and Accessories:
SafeInjection™ (#30020): On a gasoline engine, if it is tuned aggressively for water-methanol, and the tank is run dry or the nozzle somehow clogs (they have 100 micron pre-filters) and the amount of water-methanol injected is reduced, there could be detonation. Snow Performance developed a very comprehensive safeguard so an engine can be run with complete confidence on a very aggressive tune. SafeInjection™ measures the fluid flow rate in the system anytime it injects. If there isn’t enough fluid flow, it automatically sends out a signal that can be used to reduce boost, timing or switch engine management maps. No matter what happens, the engine remains safe. The SafeInjection™ can also be used with an optional gauge to display real-time flow of water-methanol in milliliters per minute, so you can see exactly how much fluid is being injected and when.
Boost Juice™ is Snow Performance’s proprietary mix of 49% methanol and 51% water. It is made in a controlled environment with special care to make sure the ratios are accurate to result in a high performance water/methanol fluid formulated for use in the Boost Cooler™ injection system. If Boost Juice™ is used exclusively in the Boost Cooler™ kit, Snow Performance offers a free lifetime warranty.
Nitro Booster™ is a great power adder designed for use with gasoline engines using Boost Cooler™ water-methanol injection kits. A proprietary blend of nitro methane and a specially developed emulsifier that keeps Nitro Booster equally distributed in the water-methanol mixture. This allows for a small percentage of nitro methane to be injected into the engine in the correct proportion with air and fuel to produce impressive increases in power. Usually, around 30 to 50hp increase can be measured. Nitro methane has fewer BTUs than gasoline, but contains oxygen and acts like a chemical supercharger and an octane enhancer to safely increase power.
Solenoid Upgrade (#40060): A solenoid is simply an electric on-off valve for fluid flow. We mount them near the injection nozzle when required by certain installations. If the nozzle is mounted below the top level of the reservoir fluid could gravity feed through the pump and nozzle but a solenoid will prevent this, as it only opens to allow fluid flow when the system is actively injecting. The other instance where a solenoid is required is when the nozzle is placed after the throttle body or carburetor (between the butterflies and the intake valve). In this location, it will be exposed to vacuum when the engine is running and the butterflies are closed causing it to siphon fluid when not needed. The shut-off solenoid positively prevents this.
7 Quart Reservoir (#40020): The 7 quart reservoir gives much more range than the included 2 qt tank, and is fairly small in size – 10”l x 12”h x 7”w (similar to a very small car battery).
Additional Nozzle Upgrade (#40004): This allows an additional nozzle to be mounted in any of our Boost Cooler™ kits. It includes a tee, or splitter, junction piece with our quick-connect fittings, a nozzle holder and a section of hose. Note – injector nozzle is not included. Mounting additional nozzles are required when you need a quantity greater than one nozzle can provide, or if you have a dual plenum/throttle body/carburetor setup to get even distribution.
Carburetor Adapter Plate (#40050): This 1” adapter plate allows a very clean and easy installation of our injector nozzles on carbureted applications using 4150-style square bore 4 barrel carburetors. Each plate has 2 nozzle mounting holes. (Mounting the nozzle below the carburetor requires a Solenoid Upgrade (#40060))
Low Level Indicator (#40035): This is a float switch and indicator light that let you know when your reservoir is running low on fluid. Simple to install and wire in any reservoir.
220 PSI Pump (#220): Higher pressure/volume pump. Only necessary in the highest horsepower installations running 3 large nozzles, or if more quantity is needed with a smaller number of nozzles. Adjustable pressure just like our 150psi pumps.


Snow Performance has several different Boost Cooler™ kits for your turbo diesel tow rig as well:
Diesel Stage 1 Kit: Performance-oriented kit for low-boost turbo diesel engines (less than 20psi). System uses a digital progressive controller to inject proportionally according to boost pressure for maximum increase in power and extremely responsive performance. Common applications are early Ford 7.3L and GM 6.5L turbo diesels.
Diesel Stage 2 Kit: Performance-oriented kit for high-boost turbo diesel engines (more than 20psi). System uses a digital progressive controller to inject proportionally according to boost pressure for maximum increase in power and extremely responsive performance. Kits available for all Ford Powerstrokes, GM Duramax, and Dodge Cummins.
Diesel Stage 3 Kit: This is the best diesel kit for both performance and towing applications because the system uses 2-dimensional injection management. It allows for all the same power increases, but because it injects according to both boost and EGT signals, it has a smoother power delivery and an active EGT control function. It also is adjustable on the fly for different trailer loads, more or less power, etc. Kits available for all Ford Powerstrokes, GM Duramax, and Dodge Cummins. Universal application also available.
8 Gallon Reservoir (#40010): The 8 gallon reservoir usually gives a range of 600-800 miles when towing around 12,000-15,000 lbs with a 1 ton truck. It comes with a mounting bracket, an extra 10 ft of hose and a shut-off solenoid to prevent gravity feeding if you ever park on a steep incline. Measurements: 16”l x 17”h x 13”w. This size allows it to mount inside of most bed-mounted tool boxes.
 
I've got a Snow kit on both of my SCs. The 91 has the MAF voltage controller and uses the stock washer fluid tank, the 93 has a trunk mounted 7 qt tank and uses a manifold pressure controller.
