 
Snow Performance Stage 2 GM MAF Boost Cooler kit for General Motors gasoline engines.
This kit uses the unique GM MAF frequency Hz output signal (on most 1994 and new GM vehicles) instead of 0-5 volts. Perfect for naturally aspirated applications and forced induction applications that build boost quickly at lower rpms. This allows for the most accurate delivery of water-methanol and allows the most cooling and performance improvement over the widest range. More power and driveability is the result.
The Boost Cooler® is Snow Performance's latest generation water/methanol injection system. The primary function of water/methanol injection is to provide "chemical intercooling".
In gasoline engines, as with any intercooler, this suppresses detonation so more power producing boost and timing can be utilized. Water, with its high latent heat of vaporization cools the intake charge and combustion. Methanol cools the charge and combustion but also acts like an extremely high octane fuel (some researchers claim as high as 120 octane) as well as adding more oxygen to combustion.
The latest competitive use is in World Rally Racing (WRC) where virtually all teams use it in some form and in diesel truck/tractor pulling competition. It is important to note that in the fall of 2004, the long standing world record in the quarter mile for diesels was broken twice (now 7.98 sec) by two different vehicles; both using the Boost Cooler water/methanol injection system by Snow Performance.
1. What are the benefits of Water/Methanol injection?
a. Greatly reduced EGTs - Decreases of 250 degrees F are common using a 50/50 water-methanol mix. Increased EGTs are an engine killer in today's performance diesel world.
b. Low cost power - Where else can you get 70-100 HP for as low as $400 along with reduced EGT's?
c. Greatly increased air charge densities - 3-5 psig boost increases are common.
d. Great for towing - more power/cooler EGT's to haul the heaviest loads.
2. 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+ while increasing power 70-100HP.
Power is increased through:
a. Intake charge cooling - Water/methanol will lower air charge temps over 200F in this application.
b. Methanol - this acts as a fuel as well as cooling the intake charge.
Where else can you get this kind of power with cooler EGT's!
3. Is this technology new with Turbo Diesel?
Water/methanol injection has been used extensively for years in high performance truck/tractor pullers. With the elevated boost levels required for peak power, water/methanol is a common means of cooling the intake charge and reducing exhaust gas temps. Also, truckers have used water injection for years to increase fuel mileage.
4. Why Methanol?
Methanol is a fuel that is extremely clean with an excellent cost/benefit ratio. ($1.50 - $2.00 per gallon.) Its high latent heat of vaporization also makes it an excellent air charge cooler which means a denser mixture and more horsepower. Because of these facts, it is a better fuel in diesels than ethanol or isopropanol although they will work in a pinch. It is extremely toxic and should be handled with rubber gloves in well ventilated areas only. Care should be taken to avoid skin contact.
5. Is Methanol Safe for my Diesel?
Methanol makes an excellent adjunct fuel. Because it has a cetane number of 4CN, it makes safe power without spiking cylinder pressures. In fact, it cools combustion so much that hotter intake charges and higher compression are required if 100% methanol is used.
6. Where can I get methanol?
SP sells 50/50 methanol water as Boost Juice™. 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. Although most contain some glycol and detergent( less than 1%), most windshield washer fluids are up to 40% methanol. Try to find one that indicates "contains methanol" and is good to minus -20 degrees F.
