1. What are the benefits of Water/Methanol injection?
Boost Cooler Benefits (Diesel):
reduced EGT's. Decreases of 250 degrees F are common using a 50/50%
Methanol /Water mix. This prevents the usual problems associated with
high exhaust car temperatures - rings sticking, holed pistons, etc.
2. Low cost power - where else can you get 70-100 HP for approximately $400 along with reduced EGT's.
3. Greatly increased air charge densities - 3-5 psig boost increases are common.
4. Great for towing - more power/cooler EGT's to haul the heaviest loads.
2. Do I need an Intercooler with Water/Methanol injection?
approximately 20 psi boost, water/methanol injection will provide all
the density increase/detonation control needed in most applications. Of
course, Intercooling and water/methanol injection would provide even
greater benefits especially beyond 20 psi boost. Most air-to-air
intercoolers are only 50-65% efficient. That means for example, that
with 11psi boost and its 120f air charge temperature increase, an
intercooler reduces the air charge temperature only 60 degrees. Also, an
intercooler will reduce boost 2 - 4 psi. on average.
3. Why not use a windshield washer pump?
must be injected at above 50psi to properly atomize. Lower than 50psi
causes greatly reduced air charge cooling as the result of larger
droplets and their reduced total surface area.
4. Why methanol?
Methanol is a
high octane fuel that is extremely resistant to detonation 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 anti-detonant than ethanol or iso-propanol
although they will work in a pinch. It has however only about 60% of the
energy content of gasoline by volume so about twice as much is used to
make similar power if used as a straight fuel. 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. How much Water/Methanol?
detonation, the ratio of Water/Methanol to gasoline is roughly 1 to 5 in
gasoline applications- 1 to 4 in diesel. In practice, you give it as
much water / methanol as it takes to eliminate detonation without
quenching combustion. The amount depends on the onset RPM of injection,
the octane of the gasoline, fuel/air ratio, cylinder head type, even the
weather conditions. Your engine is actually pretty tolerant of extra
water vapor, you will know it's too much when the engine misses and
6. Where can I purchase Methanol?
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. Methanol can be purchased on the web at
www.worldwideracingfuels.com and hiperfuels.com.
7. How long will a tank (2 qts.) last?
boost/high horsepower application, a full blast 1/4 mile run will
utilize as much as 1/8 tank. A larger tank should be considered if over
9psi boost is utilized in road racing where a tank can be used in as few
as 6 - 2 mile/ full tilt laps. Under normal street use in a 400 HP
Mustang, a tank usually lasts about 500 miles. Two reservoirs can be
used for 1-gal total capacity if desired. Turbo diesels use more qty.
and usually utilize the existing windshield washer reservoir (over 4
qts. in most cases) or the new 8-gal reservoir upgrade. More will always
be used when the system is first installed, less when the novelty wears
8. Can I use windshield washer fluid?
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".
9. At what boost level do I introduce Water/Methanol?
superchargers/large turbos: Generally, at 50% of peak boost the
recommended quantity should be introduced. Positive displacement
superchargers/ fast spooling turbos: injection should occur at or near
peak boost to avoid combustion quench since peak boost occurs so fast.
10. What ratio of Water/Methanol is recommended?
A 50/50 ratio
is recommended. This has been demonstrated to be the best for charge/air
cooling, excellent detonation control, and controlling cylinder
temperature. This includes diesel applications where water conditions
the combustion of the methanol so combustion timing isn't affected.
11. Many recommend Denso Iridium spark plugs in boosted applications. Will these work also with water/methanol injection?
spark plugs are highly recommended with the Boost Cooler®. Iridiums,
with their low firing thresholds and intense spark, allow for larger
quantities to be injected sooner without misfiring. This allows for more
cooling of the intake air. If you have a misfiring problem, nine times
out of ten, Iridiums will clear it up.
12. 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. In fact, water/methanol reduces the
probability of engine destroying detonation. Think of it as an insurance
policy against detonation.
13. Can the Boost Cooler® be applied to naturally aspirated and nitrous engines?
1.Naturally aspirated/high compression engines:
application, water/methanol injection allows the use of pump fuel in all
but the most extreme situations which effects tremendous cost savings
as well as horsepower increases due to air density increase and realized
timing potential. The system is activated by a throttle switch so that
injection takes place only during high engine loads when needed.
2. NOS engines:
With NOS, water/methanol injection allows the use of full timing even
with large (250HP+) quantities. Injection is controlled by the same
means that controls NOS injection.
aspirated/stock compression: With naturally aspirated engines with less
than 10:1 compression, water/methanol is used typically in warm climates
to get the intake temps back to 60°f. Benefits include: 10-15 HP
increases from air density increases and full timing, Increased gas
mileage, and carbon free combustion chambers. Activation is by a
throttle switch adjusted for onset engine load. With this application,
the nozzle is sized so that no more than 10% of total fuel consumption
at peak flywheel HP is injected.
14. Why is Water/Methanol injection so effective on Diesels?
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 250f +
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!
15. Is this technology new with Turbo Diesel?
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.
