Thanks so much for the vid - I finally understand water/meth injection lol. One question though: since this type of mod can increase power by using more fuel, does that mean fuel economy is affected negatively?
i have a question i understand the water Absorbs the heat but what does the methanol do. does it just increase the octane level of the fuel when it gets mixed with the petrol or does it have a cooling effect like water ? and why do people run 100% Meth ?
@mrxbrightside mostly turbo/supercharged cars because they are prone to more heat and detonation. but if you have a highly modified NA with very High compression pistons then it will help stop detonation. the old hotroders from the 1950s used to use this system to stop detonation so its nothing new. also WW2 fighter jets used water injection as well
@gsrangelmon cool. I first heard of it from when i had a tuned TDI, again for the heat reasons. Just always wondered if it worked with NA aswell. Thanks for the info :)
Great video, I honestly thought meth injection was like a form of Nitrous but I was completely wrong, it's like getting water sprayed on u on a hot day while working out so u can focus a little better on power than heat...Freakin great!
Not to throw stones, but as Corky Bell wrote in his Turbocharger primer "Maximum Boost"... "Water injection is a bandaid for a poorly designed turbocharger system"
@rabbott430 HAHA! Funny but some have tried this - with not so good results. Here's why: the size of the water droplets is too big and won't atomize correctly, so you have water that is in a droplet that is too big to vaporize (and thus can't cool things off) entering the combustion chamber. Problem 2 is the siphoning effect that will occur when the engine is in vacuum - your engine will suck water out of the tank and could hydrolock.
I saw this stated in the website "Legal in California only for racing vehicles which may never be used upon a highway." Why such a control implicated in California? What is the cons for user who travel mostly on street and highway?
i dont understand...engine detonation, so if that happens while you drive your engine blows up and you die....lol does it go off like a bomb or does it just damage internals?
@sergsrt8 Detonation can result in a pretty catastrophic failure, but the damage is done by multiple, small events, not one huge explosion in a cylinder. Think of it more like it's chipping away at the ring land or dome of the piston. Either way when a piston lets go, it's a big deal!
Does it make sense to install this on a NA vehicle? Will my 2011 5.0 mustang benefit from a methanol injection? Should I use more methanol in my water/methanol mix for more power? Thanks for the info!!
@1970351cmustang Short answer... YES! Even on a N/A engine you will see power gains. Check out the Aug 2011 issue of Popular Hot Rodding Magazine, they cover the topic of N/A Water/Meth injection. However they did theirs on a Carburated 302 setup. Check out Snow Performance for Mustang kits.
@KoalaJacks Yes to and extent. When running meth it is used as a supplement to the fuel meaning that you aren't pumping much of your gas into the cylinders once you make boost. Your average meth kit will kick in at 5-7psi and peak at let's say for this example 18psi. You build boost at 5psi your meth nozzle sprays the atomized mist into the engine there for replacing 90% of the pump fuel you would use. Therefore when you get on it you are using meth, not the gas in your tank.
@getalife04 Dude, you are way, way off on this explanation. W/M injection does not replace 90% of the pump fuel you would normally use. You couldn't even get your car to idle using only W/M. The typical W/M ratio is 50/50 by weight and you can't even get that mixture to burn. Nevermind run your engine on it's own especially at full throttle. Unless you rewrite the fuel map, or your ECU has wideband lambda capabilities, you save ZERO fuel. At best, at WOT, you might be able to reduce fuel by 5%.
@TheAristotleQ Ok let me elaborate a little here. When you run meth at idle everything is normal you are using just the fuel in your take like normal. But once you build up to say 7psi of boost the meth kicks in where you can pull back the pump gas. And how does a 50/50 mix NOT burn? Once it combusts in the chamber the cooling effect of the alcohol reduces the thermal temp and decreasing knock. Also the water offers a cooling effect and steam cleans the engine.
@getalife04 We agree everything is normal at idle. You said "You build boost at 5psi your meth nozzle sprays the atomized mist into the engine there for replacing 90% of the pump fuel you would use. Therefore when you get on it you are using meth, not the gas in your tank."
This is not true. If you tried using only 10% gas and 90% W/M at 50/50 mix, the engine would not run. If you held a lighter up to a W/M nozzle spraying 50/50 water/meth, it will not ignite. That mixture is not flammable.
@getalife04 Think about it, if cars could run off 50% water and 50% methanol, why would we need gas? Also, even if you could, W/M nozzles are WAY smaller than fuel injectors. Take a 400 hp 4 cylinder car. Uses four 700cc injectors. That is 2800 cc’s of gas. It's common to use 1cc of W/M per hp. 400hp= 400cc W/M nozzle. So how would a 400cc nozzle replace 2800cc of gas? At WOT, if you pump too much 50/50 W/M, it will stop the gas from burning. The car will stall. 50/50 W/M is not flammable.
@TheAristotleQ Ok so I was a off with the amount of fuel that it replaces but it does make a difference in economy and the amount of fuel you have to dump in order to make the same power. The best benefit is the knock prevention and the ability to up the boost and the timing to create more power. I read 30mpg at full throttle lol.
@getalife04 It did nothing noticeable for my fuel economy. No one I know has ever gotten better gas mileage on a forced induction gas engine. I have a W/M set up on my car. When I drive mostly freeway, the system doesn't come into play. When I drive mostly city, the only difference I notice is that I never lose power due to high intake temps and heat soak on my stock intercooler. Especially during summer temps.
@TheAristotleQ Did you ever have your car running hard on just straight pump gas? I did before and there is a very noticeable difference. When I get in it before I could just about watch my gas gauge go down and with the meth it is a lot better.
@KoalaJacks I can assure you, it does NOT increase your fuel mileage. The system is only active during acceleration, so unless you drive 98% of the time with your foot completely to the floor, you are not saving any gas.
Really nice video guys. Really love your products. Keep up the good work.
Where do you most often install the meth nozzle; Compressor inlet, or post intercooler? Also, since it creates a slower burning combustion event, more ignition timing must be added, correct?
@koutz4 Thanks for the props! We typically like to install the water/methanol injector post intercooler to avoid water/meth pooling up in the intercooler. Although some will install it pre intercooler and pre compressor we like to install it post. Another thing to keep in mind is if your car is equipped with a MAF than make sure it is post that as well. As far as ignition timing you can leave it stock, but to get the most benefit more timing can be added to your ignition map.

The methanol has two roles in the injection system. It does cool the intake charge, but it also increases the octane level of the fuel as well.
