Methanol Injection 101 Stop Listening To Facebook Car People

Methanol Injection on an LSA Supercharged Chevy SS
Often people say to use meth for cooling and it doesn't need to be tuned for it when using it for cooling. Well, methanol is a fuel so it will change the tune. You can spray chocolate milk on your IAT it will drop the temps that are registered but it's not going to make more power.
On another setup I did the same test with a single M5 (size not vp m5) nozzle on using vp m1, the single m5 nozzle made the AFRs go from 11.9:1 to 11.3:1 which isn't horrible but will still need some tuning to get it 100% right. Now if the car was at 11.5:1 then a single nozzle was sprayed that would put the AFRs around 10.9-10.8:1. The more methanol you spray, the more it will change the AFR.

I love videos like this. I know you may get a lot of backlash for this video, but as a tuner, I am 100% in your corner. This video is 100% backed by data. Whether you like it or not, this is absolutely what we see on combinations like this time and time again. In my experience, DI stuff that doesn't have enough fueling really seems to benefit a lot from 100% methanol injection pre-tb. If you are running ethanol with port injection, the gains are minimal...even with high iat's. You got a like and sub from me, homie. Great video!!

[@andrewd843]

I appreciate it! Everyone who had ever argued with me online never provided data. Now a turbo car or centrifugal supercharger sure they'll see IAT drops from the methanol but still if it's not tuned they'll lose power too.

[@jamesesquibel2279]

I was under the impression that stoich for pump gas was 14.1 for e10. Great info and something over looked often.

[@andrewd843]

It is. I don't think I mentioned anything about 10% ethanol fuel in this video or any video ever.

[@camscustombuilds]

Great video. A couple of things to note for people looking to run water/meth or meth injection. A single nozzle location can cause unequal distribution. You may have cylinders that are flooding with meth and some that barely get anything. Also, when you tune around a meth kit and the meth kit dies, you better hope there is some kind of fail safe in place.

[@andrewd843]

Why does everyone keep mentioning water meth? This video is for 100% meth not water meth that makes a huge difference. Methanol is fuel, water is not. Water cools, Methanol adds octane. But what happens when a fuel pump dies? Bad stuff can happen, once again methanol is fuel so it should be treated as such. I've seen more fuel pumps die than I have meth kit pumps.

[@andrewd843]

Also, don't modify anything if you're not willing to take a risk of parts failing and catastrophic damage.

[@GA1.6T]

A couple years ago tried m1 instead of 50/50 boost juice and was blown away at how much of a difference it made without any fuel or timing changes, it had to have been 5-10hp. The power loss comes down to what the air fuels were before you start injecting meth. For instance if you're already running an 11.5 AFR WOT on 93oct, once you start injecting it will probably go to around 10.5-10.0 so you lose power (more or less depending on nozzle size). If you have a stock turbo car with a factory ecu that will be probably the best mod you can do, simply because the ecu will adjust fuel trims and timing modifiers automatically

[@andrewd843]

Correct, I explained that. It's a fuel you can't add fuel and not tune for it, especially when spraying the house down with methanol it goes so rich it'll lose power. Water meth isn't nearly as bad, but the gains from tuning are there 10 out of 10 times.

[@GA1.6T]

@@andrewd843 Absolutely. I added 2 degrees and took 5% away up top and it felt alot better. Great video btw really good info 👍

[@RhynoE28]

No tune on my 09 mini Cooper S with direct port meth injection. I can run dry and not have issues. However I tuned my 04 STI on Meth/ E85 and have a premium gas tune as well and if I run dry in my STI I will have problems. Tuning isn't my strong suit as I have dyno shops for my builds. I do have about 10° cooler temps. Also. Are you running a LS7 or L77? Didn't hear a turbo or supercharger over exhaust but that could be why you don't see really any difference. Doing this on a F.i motor you will see a difference. My mini Cooper S just has it to clean my valves and run cooler. If I did get a tune I know I could get about 100 extra HP. Coming from the hot rod scene as well I get what you're saying and agree.

[@andrewd843]

Running no issue and making more power are two different things. Lots of things can be done doesn't mean they're gaining power unless you're really laking a fuel system.

[@eddiearchuleta615]

On a PD blower you want to spray pre and post rotors with a 50/50 mix of water and alcohol preferably isopropyl alcohol as it cools even better than methanol and has more power in the fuel

[@andrewd843]

Water doesn't compress. That can cause bad things to happen in the rotors if you spray a lot. Water is better for cooling. I don't use methanol for cooling. I use it for the octane.

Some people still think injectors, flex sensor, and sometimes a fuel pump are worth the money for 5-10hp on some NA ls stuff, so what it's worth is up to whoever is spending money. Meth injection can be worth well over 100whp on the right combo, but a mild lsa combo isn't the right combo for big gains.

[@SubiCarLous]

How is the power gain of normal fuel to meth/water injection? In this case it's not really worth to go to E85 + meth/water inj because the power gain is really low, right?

[@andrewd843]

I don't mess with water meth. Water meth is better for cooling. But I wouldn't recommend spraying water into supercharger rotors. Water meth power gains will depend on how bad cooling is, and how it gets tuned. Straight meth will depend on how tuning is and what the base fuel was being used. Pump/meth will have bigger gains than e85/meth.

[@SmolKTN]

Hey man, please help me understand this. My car is currently at the mech, he's doing an upgdraded intercooler for my Focus ST 2016, he's saying I should also do watermethanol injection. He's also saying because we are at altitude, it will help gain power without a tune. I am confused now, he has done a lot of my type of car and he swears by it. What am I supposed to do now? What would you do if you had my car to work on?

[@andrewd843]

Water meth is not straight methanol that's two different things. Water doesn't change fueling like straight methanol does. So it would depend on 1. How your tune is 2. The water/meth %. 3. How much water/meth you spray.

[@b00sted_SS]

Maybe would have helped the comments here if it stated NOT water/meth, alot assumed you’re talking about adding water/meth to a turbo application. Absolutely not what you’re talking about. Great video now that I understand the application. Blower + M1 . Not pump gas turbos + water meth.. apples and oranges

Is this true for cars that have a Wideband o2 sensor where the ecu can adjust ratios on the fly? I got WMI spraying before the supercharger (2023 F pace SVR) mostly for cooling. It gets 100+ F in the summer months. But, I'm wondering if my car will automatically pull some fuel out to prevent it form going to rich?

[@andrewd843]

Honestly, that depends on how the tune is set up. Just because something has a wideband vs narrow band doesn't mean the full corrections are setup to pull that much fuel. It 100% could do it but doesn't mean it will do it. Some aftermarket ecus you can program that allowed fuel corrections, not sure if everyone oem will correct 100% or if they have a limit on correction.

I have a totally different platform, and my car was slower with water/meth, I got it because many people said that it would make more power but it didn’t, it did help with knock and IATs, however after I got it tuned, it added around 40-50 horses, I can feel the difference. Don’t believe the hype, you need to tune or don’t bother.

[@andrewd843]

Water/meth is good for cooling. Same with water injection. Water isn't fuel so pure water injection or even water/meth mix won't have nearly the same drop in power since it's not over fueling the motor. However water/meth mix still has methanol so it will change the AFRs and need some tuning to get right. Whenever fuel is introduced it needs to be tuned.

[@timweb1510]

Haha i laugh at em all. I was using a rigged water injection setup in a mk1 golf I had with a mechanical ahu tdi swap back around 04-05. Since i didn't have an intercooler i blew it right into the air intake going to the turbo. It worked great for years and crutched my lack of intercooler. Just a plain old washer botrle filled with juice , a piece of copper line and an old carb jet.

[@kanenaysmith9287]

Would there be a difference if you were not running ethanol fuel if you’re running normal pump gas

[@andrewd843]

For power? Or cooling? Pump/meth makes less than e85/meth but meth will have larger gains over on pump gas than it does on e85 if that makes sense. But cooling IAT wise won't be any different on a pd blower spraying before the rotors. It will also still need to be tuned or it'll be overly rich and most likely lose power.

[@kanenaysmith9287]

Thanks for the reply. i am building a 2jz turbo and i am trying to get away without having to use E85 because its hard to get where i live. I am also curious if running meth/water on a ford ranger 3.2L common rail would have any benefits.@@andrewd843

[@shotamakarashvili3714]

Well, even in AEM WMI manual it says the AFR to be adjusted when spraying yet it's just 50/50 with water. Sure meth is changing Lambda, why wouldn't it..?

[@andrewd843]

90% of people on Facebook claim you don't need to tune for meth and it doesn't change the AFRs which would be impossible so that's why I made this video. Alky control instructions say similar things. I knew the answer but people need to see it sometimes.

[@Drainclinic]

Hey my car has been tuned for 93 and meth I’ve been using m1 recently I haven’t been able to find m1 they only had m5 you think I can use the m5 with out any problems or do I need to adjust the tune

[@andrewd843]

I'd definitely ask whoever tuned it. I've done some back to back with m1 vs m5 and they usually needed want different tunes. But have no idea how your tune is.

[@RRahmani_performance]

Did you truy your „meth tune“ map just on e without meth? Just in case you was not running best ign on ethanol map

[@andrewd843]

@RRahmani_performance that wouldn't work. If my methanol tune is loaded the meth is on. If I don't plan on using methanol I load a different tune. About 10% of total fueling is methanol so that would be a lot of fuel missing.

Is spraying meth before the blower ok? I’ve heard mixed things about putting meth before the blower can be harmful? Any thoughts on this I have a nuespeed supercharged 2 liter Volkswagen and the charger is apart of the intake manifold so the best cooling affects would happen if I sprayed meth before the blower

[@andrewd843]

I've had the meth for about 2.5 years now and my rotor pack in the supercharger still looks exactly how it did the day I installed the supercharger. I've heard methanol will eat the coating off the rotors but if it does I guess it takes a long time because I've gone through a lot of methanol over the last 30,000 miles and no issues so far. I wouldn't necessarily spray a water meth mix through it since water doesn't compress.

[@Everything8Valve]

@@andrewd843 ok so you recommend just meth for the octane boost?

[@andrewd843]

@Everything8Valve that's what I use it for. Not sure how it would be with your supercharger. But on this combo the methanol evaporates before it ever sees the IAT so meth or no meth there's 0 temp change for the air charge after the rotors.

[@BigMotorLover]

What about pure water then? My car doesn't offer custom tuning, only off the shelf. So no advancing or retarding timing. So what about pure water?

[@andrewd843]

Water injection shouldn't change the AFRs at all since water doesn't burn and isn't fuel. A lot of people run water injection for the cooling effect. Something like boost juice or a meth/water mix will give you the benefits of both some extra octane and cooling of water but won't be so much that it kills the power and makes it overly rich. I just prefer straight m1 since it'll make more power, and I don't have temperature issues.

@michaelpopp6340 I know if you can get e85 don't waste time with water methanol. A supra with methanol injection at my local turner got over 200hp extra because of the knock suppression. They Could add 12psi on top of the regular pump fuel tune. Methanol can handle over 40/1 compression without knock e85 can handle 25/1 without knock. So methanol is very helpful even with small amounts.

On a n/a application, wouldn’t the results be less significant to the point where it wouldn’t make since to run it, vs running it with boost?

Why would you spray methanol on an NA application? It would need to be a pretty wild combo to pick up good with methanol injection or to even need methanol injection.

If this vehicle was the direct port, it would see an increase

And plus dual nozzle is way too much meth if you’re just gonna use it for cooling

[@andrewd843]

@patricklala2366 you know how many people run turbos or centri blowers run dual m15 nozzles for "cooling" a lot But also, on those other videos, what did they change? Was timing being pulled for heat? Was timing being added for cool temps? If everything is the same and you add meth rather than one small nozzle or a lot of nozzles, it's not going to pick up power. You can't add a slower burning fuel without changes, and it picks up power regardless of the power adder unless without meth its already octane limited. I've done this test over and over single nozzles, dual nozzle turbo, centrifugal, and pd blower. You can spray chocolate milk on your iat. It'll read lower temps, but it doesn't mean it's doing anything. Meth doesn't care about IATs. Why do you think methanol cars are usually non intercooled. What do you mean direct port? So 8 meth nozzles aren't too much, but 2 is? That doesn't make sense.

This video is misleading and does not even consider several scenarios where a tune would not be needed. I'll explain one of them. it's not necessarily about "adding more power". Cars that struggle with high IAT's can easily benefit from a WMI system without a tune. It's pretty simple - instead of the ECU pulling timing, boost, etc., and lowering performance overall as a safety measure against the high IAT's, the car will be able to run freely without it pulling back in certain areas to protect itself from the high temps. Simply allowing the car to operate with these lower IAT's without performance being held back is a HUGE benefit that can be achieved without any special "meth tune", and yes, you'd be allowing your car to make more power than it would without it. Thanks for coming to my Ted Talk.

[@andrewd843]

Water meth and methanol are two completely different things. This video was to a specific group of people. Every week, someone makes a post about spraying the house down with pure meth (not water meth) and claims it doesn't need tuning. Water meth is great. Methanol is great. Both only work when done right. This video isn't about water meth or about cooling. IAT didn't change at all with or without. It's about octane. I wouldn't recommend spraying water in a PD blower. Water doesn't compress that can end extremely bad if too much goes in the rotors of the blower. It'd be no different than tossing a bolt into the rotors. But thanks for your comment.
