There's your answer.

 

Yes, and doesn't produce power. Only resists detonation since it doesn't burn.

 

Water does not have a octane number- it doesn't mean it is infinite octane number in th R+M terms. It controls knock in a different way.

You can call it "effective octane" It can not be calculated using the R+M method.

 

With that being said, realistically expect the same results as you would with 100 octane fuel if you use straight meth and 93 octane pump gas. Granted, this is with a large amount of flow coming from the alky kit.

 

has anyone tried contacting an evoM mod to ask them to take the ad down?

 

OK, let me take a stab at trying to explain their advertising propaganda. If you run a 50/50 mix of meth/water you can see UP TO the equivalant of 120 oct. Water does not have an actual octane number using the r+m method, however by using water you are cooling the cylinder temps creating a "false" octane I guess would be the better way to put it.
With the added cooling of water and the actual octane increse of the meth it will give you the equivalant of running 120 octane gas even though you really arent.

Injecting at 3% water to fuel running a 12.5 AFR will provide the same cooling effect as running 10.0AFR. Running a car rich is to provide extra cylinder cooling. These numbers are no gospel by the way they are meant as starting points for tuning. Every car will act differently to the injection. Some companies recommend 10-15% injection of water to fuel, some recommend a higher injection rate of about 20%. The injection rate will vary engine to engine.

So in theory the added cooling from water/alky injection could theoretically be equivilant to say 120 oct. This is all theory. Maybe Snow shows larger gains on Diesel engine and are using that as their basis.

The advertising is false though. It should say up to the equivilant of 120oct.

I am sure Aquamist or LMS could do a better job of explaining this than I did.

 

Well, the only way I see that it can be proven (which is possible) is if they ran the car with 120 octane race fuel (timing tuned as aggressively as they can get it) and then ran the car on 91 octane and their kit with similar results. Obviously the race fuel will create more power but I'd be more concerned with how the car responded on both setups with the same aggressive maps.

 

There is absolutley no way that 120octane race fuel will be the same as pump with meth. No matter what combo of meth/water....there is no way you will reach the effectiveness of 120 octane gas.
This is based not on math but experiance, I have run many water/meth combo and while they do kick butt, they are not race gas.

 

shyte add, shame on you snow performance.
