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!!

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.

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

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.

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

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

Methanol injection is for high compression and boosted applications keep the pistons cool and free on detonation when running higher boost with pump fuel and helps hugely on directinjection turbo motors.100% needs to be tuned and ls a type of replacement for people that can't get e85

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.

Looks like anyone shooting methanol before the turbo/supercharger wouldn't see any difference in actual IAT's but man I don't know how you couldn't see IAT's drop drastically on a high boost/high iat car if the methanol is introduced before the intake.

Now I want some dunkin coffee😂

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

Watching it from Australia mate big thumbs up with the video great bit of info 👍almost finished building my Intercooled LS1 turbo and am contemplating fitting the kit on to mine, I'll run the E85 first and go from there and decide

Good work man

I used to have alky system in my boosted vette and sierra but I switched them both to prometh with upgrade meth pump PM190 and VC-50 gauge meth/boost i felt this is the best combo lil expensive but worth it

Thank you for proving that the gain is not worth it

I like the chocolate milk idea 💡

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?

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?

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

Andrew what is target lambda for E85 and meth injection, assuming actual E85 for my questions sake
