How well does Methanol injection work on N/A and N20 applications?

I thought the forced induction people here could share their thoughts, or give a more precise answer than the below information offered from Snow Performance.





13. Can the Boost CoolerŽ be applied to naturally aspirated and nitrous engines?

1.Naturally aspirated/high compression engines:

In this 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.

3. Naturally 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.

I don't know exactly how I feel about it but I'll take a stab.

If you tune your engine specifically so it runs best with the methanol flowing you become married to it. In other words you're now a meth addict, at least your engine will be.

If the NA system is set up for a constant flowrate you'll want to be able to adjust your gasoline delivery to compensate as your rpm changes. This might be rather tricky.

Too much emphasis is placed on running "full timing" on nitrous. Your timing requirements are quite different on the bottle. There is fuel available with a slow burnrate and very high octane specifically for nitrous ProMod engines and other heads up catagories. These engines still don't run more than 15 degress, often much less. A typical plate system, such as a BigShot on a carb car running good gas will still retard the timing 15+ degrees because that's where the engine runs best.

$300 plus incidentals for 10-15 hp WOT isn't a bargain in my book for something that requires maintenence and has moving parts but your opinion may differ.

Methanol is proven to work with forced induction. I'm not knocking that at all.

 

the meth injection works ok on n/a applications. not a great increase in power 5-15hp. the problem is the tuning. you will notice no gain unless your timing is optimized which mean computer programming. on nitrous the same applies. the horsepower gains are there from the increase in timing. mustangs work great with meth because there is no knock sensor and where you set the timing is where it is at. gm like to throw tons of variables into the equation when it comes to timing, if your not racing don't attempt it. i have dynoed supercharges car with meth and seen decreases beacause of lack of tuning. once tuned they work great for supers ot turbos
