Давайте не будем дальше вступать в дискуссию так как, то что я делаю, и как, считаю правильным. У вас, повторюсь, есть свой проект и я заметьте в него не незу.
не я одна говорю что вы не правы, а вы все равно что то пытаетесь доказать. причем обсуждаются реально НЕ существующие проблемы.
про водометанол, ФАК:
Boost Cooler Benefits:
•Greatly 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.
•Low cost power - where else can you get HP for $500 along with reduced EGT’s.
•Greatly increased air charge densities - 3-5 psig boost increases are common.
FAQ:
1. Do I need an Intercooler with Water/Methanol injection?
Up to approximately 20 psi boost, water/methanol injection will provide all the density increase/detonation control needed in most applications. Most air-to-air intercoolers are only 50-65% efficient. That means for example, that with 11psi boost and its 120°f 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.
2. Why not use a windshield washer pump?
Water/Methanol must be injected at above 50psi to be properly atomize. Lower than 50psi causes greatly reduced air charge cooling as the result is larger droplets and their reduced total surface area. At 100psi it more like a very small shot of NOS, and also uses less to make more power.
3. Why methanol?
Methanol is a high octane fuel that is extremely resistant to detonation with an excellent cost/benefit ratio. ($2.00 - $3.00per 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-detonate than ethanol or isopropanol 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. Although most windshield washer fluids contain some glycol and detergent, most fluids are up to 50% alcohol (methanol, ethanol, isopropanol) and make an excellent Boost Cooler®. Try to find one that indicates contains methanol. The best place to find a perfect mix would be in a window washing solution manufactured by Prestone: Prestone “De-icer 32below” is a perfect blend of methanol and water.
4. How much Water/Methanol and can I use windshield washer fluid?
To prevent detonation, the ratio of Water/Methanol to gasoline is roughly 1 to 5 in gasoline applications. 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 loses power.
5. 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. Methanol can be purchased on the web at
www.worldwideracingfuels.com and hiperfuels.com.
6. How long will a tank (2qts.) last?
In high 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 400HP SDS powered Mitsubishi Eclipse V6, will usually lasts about 500-700 miles. Two reservoirs can be used for 1-gal total capacity if desired.
7. At what boost level do I introduce Water/Methanol?
Centrifugal superchargers: Generally, at 50% of peak boost the recommended quantity should be introduced. Injection should occur at or near peak boost to avoid combustion quench since peak boost occurs so fast.
8. 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.
9. Many recommend NGK Copper core spark plugs in boosted applications. Will these work also with water/methanol injection?
NGK Copper core spark plugs are highly recommended with the RIPP Boost Cooler. NGK Copper cores, 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, NGK Copper core will clear it up. Will water/methanol harm my engine? Most of the mixture is evaporated before it hits the combustion chamber; since we inject it at such high pressure also, injection only takes place at high boost levels minimizing all 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.
