   Straight meth should give you more power. Depending on how much you are injecting. Excess injection will rob you of power. I suspect injection was too much hence the reduction in power.

2. 

   Meth that U don't want in your car g

3. 

   does it also make less power on a turbo diesel if you strap it straith on without adjustments? I heard the results on diesels are much better than petrol engines.

4. 

   Hi guys! Was the experience of injection of water-methanol on a naturally aspirated engine without a turbo? It would be very interesting to hear or read about it. (:

5. 

   All that talking about tuning, then we never got to see the car tuned? Lame

6. 

   What this shows is your custom tune is running as rich as possible which isn't normal unless you are running a dyno to meticulously tune it that way. This also shows you are probably missing potential where if fell off when you were running 100% methanol. Perhaps this is because the higher octane of the methanol having benefits at higher rpm? Perhaps you aren't advanced enough on your current fuel? Which would also prevent any gains. An engine with a knock sensor and self advancing timing would pay off or if you were more aggressive with your timing im general. If you think about it, the water is also offsetting the air in the chambers which is further enriching your fuel. So you have a few things that most people wouldn't be facing, 1. Fully saturated air to fuel ratio, 2. you are probably dumping a little extra fuel past saturation to mitigate heat that the cooling system cant handle, 3. Loosing boost from lower exhaust gas pressure. So you are half right. MOsT people would benefit only those who are tuned to the gills should have a negative effect.

7. 

   Thought the whole point of water/meth injection was for running on top of regular gas. It seems a waste to do the test by using an e-85 car, since the whole point of using e-85 is to get the same benefits of water/meth…

8. 

   How would this go on a car running 98? Obviously by not changing the tune is literally a waste of time for everyone , you’d tune it to suit

9. 

   Would full bolt ons, a catless downpipe, and a piggy back that increases boost justify as a tune for the addition of a meth kit?

10. 

    What is next? Watch this before installing larger ID Injectors?* Watch this before upgrading an upgraded or adding a turbo?* Watch this before installing a stroker kit?* *Without re-tuning.

11. 

    check my channel for a diy water injection with ammonia

12. 

    Ethanol and methanol are very similar and you already get the benefits from water meth with E85. If you did this with gasoline your results would be different but you'd still want tuning to get the most out of it.

13. 

    Do people really think if you plug in water meth then it magically increases power without a tune?

    Also water meth is better on 98 not E85.

14. 

    With the right piggyback or ECU tune and proper WMI injection kit, you can increase power by 50 or more whp.

15. 

    This is misleading video, you are running on E85 and on engine that is already tuned to maximum. You throw in water meth and you completely screw up the tune, as you have said. Why moderate water meth injection on daily cars with bit more power is ok and deserves the hype is when you use normal pump fuel and you make it work when your engine gets quite hot and already starts to retard ignition. What you get with moderate water meth is that retarding shall not be so severe, if at all, and you preserve the power. Again, not the task for average Joe and for sure not "bolt it on and forget about it". Bit of control and testing is a must in any situation.

16. 

    E85 is a race fuel. Most ppl and car enthusiasts are running petrol.
    So I think that by lowering the intake temps you will gain power. Because think of summer. The intercooler cant lower temps below ambient. Do a couple of hard runns and you get hest soak. ESPECIALLY with a smaller turbo turned up high. The air charge will go up to 50C and more.
    The ECU is simply going to detect knock and retard timing thus you loose power.
    So cooling air charge even without writing it into the map is effective in my opinion.
    Also any change in air fuel ratio is going to be detected by the o2 sensor and ECU compensate.
    Also if you write the w/m into the map you will have to be careful not to end up with an empty w/m reservoir.

17. 

    is there a follow up video?

18. 

    By chance what size nozzle was used for injection? Asking for a friend

19. 

    So u test water methanol without adjusting the tune? Of course its going to make less power when u add more fuel. Ur drowning it out with fuel. Target the same afr with and without meth. U will most definitely pick up some power. Dont have a unfair n biased test. Spreads false information.

20. 

    It’s kind of a botched test. Should be testing it on a car that isn’t capable of reaching peak performance without assistance

21. 

    No point using meth and e85 as I’m guessing your not limited by knock with the E85 in the first place

22. 

    No follow up on this? The water/meth also saturates the IAT sensor and reports false "over cool" readings that don't represent the actual charge temp as a whole. So we can't use the data provided by thermistor type temp probes. If the reported numbers were true, methanol inj would be more efficient than the typical A2A intercoolers. Which isn't the case, proven by power output VS IAT on the dyno. Without the common distribution issues, I'd think a rotary could go extremely far with a TON of methanol injection directly in each runner. While I Don't think you need much additional timing, you could run a much healthier amount of boost.

    What happens with a diesel, td 42

24. 

    lol lost 40hp

25. 

    This is exactly the kind of comparison I have been looking for. All of the other water / meth installs I've seen involve a new tune before the next dyno.

26. 

    Not surprising at all

27. 

    Putting it in simple terms an engine makes power from the amount of oxygen you can get into the combustion chamber(not fuel) and when you add water you are replacing some of the oxygen with liquid which is why you lose power

28. 

    This video will mislead a lot of guys with little experience.. water meth can save your engine and gives big advantage to cars running small turbos high boost with small intercoolers pushing limits. In this case the system is already very efficient running e85.. 100kw less I laugh

29. 

    Change the tune for it. Duhhhh.

30. 

    Did you guys ever tune this properly before you sold it ?im hoping to get my e85 & meth to work together in my fd gt35r maybe you have any tips

31. 

    What interests me about this is, your tune stays constant. But if someone is running a turbo car with a factory ECU, they usually lose power because the factory ECU will pull timing. But if they want to turn up the boost and add water/meth injection wouldn't the factory ECU add timing back in? Also less chance of detonation I would think.

32. 

    I once ran a car that wasn't tuned for meth or e85 with WMI and about 30% e85 in the tank. It actually ran amazingly well with a noticeable gain in power and reduction in 0-60. The fuel trims were actually good (-7% short, -2% long) timing advance stayed higher overall.
    I was running about 50% meth. Boost temps dropped to nearly ambient.
    I was using a snow stage 2 progressive kit, didn't have it full duty cycle. I set spray to start at 2psi max at 50psi. Most boost the car saw was 15psi. So as you can tell it never went full duty cycle.

    Just putting my experience out there.

33. 

    E85+WMI? WTF

34. 

    This is a terrible test. Tune the car for both and then make a comparison.

35. 

    I think it depends on what ECU you’re running. I’ve dynoed my Mazda Cx7 (same engine as Mazda 3/6 MPS) and saw a 5 -6hp gain all across the rev range when it was on factory setting (unflashed) running a small 63cc jet. Seems like the ecu detects the cooler air and runs more timing (u can evidently see 1-2 degrees more). Running 50/50 mix.

36. 

    Thanks!

37. 

    You lost me on "Fuel part of this equation won't change". One of the reasons for WMI is to alter AFR. It richens the mixture hence the ECU can advance timing to make it leaner. All you end up doing is flooding the system with too less air and too much fuel.

    If you are loosing power, you installed your WMI wrong, simple as that.

38. 

    E85 already has a cooling effect. you'll see your biggest gains when running pump gas. if you use 2 things that have a cooling effect then 1 gets cancelled out and you can lose power by cooling the combustion too much. run pump gas and retest you'll see different results.

39. 

    If you don't fully understand something please don't make a video on it.

40. 

    Use a wideband for tuning. It reads in lambda and doesnt care what fuel(s) are being burned.

    Interested in a pt2 where you tune for it.

41. 

    Yes but what happens when you tune it in

42. 

    Broomy did you end up any further testing on the dyno?

43. 

    But ROTOR…….. What about us broke kents who can only afford pistons and camshafts…..?‍♂️?‍♂️?‍♂️?‍♂️?‍♂️

44. 

    This is an incredibly deceptive video… Running meth injection on a flex-fuel vehicle is uncommon… its choosing one of the two where people are finding the gains that are being dismissed here.. the title of this video should be "Watch this before installing water methanol injection on a vehicle already tuned for/running E85"'…. the "matter of fact" blanket statements in this video's outro are completely false when taken out of the context of their vehicle's specific setup…. They've already gotten the bulk of gains W/M injection can give by running E85.
    I.E.- The countless amounts of people getting considerable gains from meth injection are not running E85, people…
    Those running W/M injection on flex-fuel vehicles are doing it mainly for engine safety, not performance gain…. WMI is a decent 'bolt on' power gain for non-E85 forced induction vehicles.
    Google "e85 meth injection" for yourself and you'll quickly see that this video is either pure ignorance or click bait…. my vote is on a mixture of both.
    I knew something was fishy before even watching this and seeing "water or meth" on the thumbnail… #RedFlag

45. 

    Id like to do water only! Love the concept but dont know much about where to start. Any ideas?

46. 

    great comparison! What happen in diesel engines with the same tests??

47. 

    But do it on a standard car that has heat soak problems. And a Ecu that self adjusts. And is constantly pulling when things get hot
    Like most new factory turbo cars

    Rather than a tuned race engine already running a fixed map ecu and a very high knock resistant fuel

48. 

    So if you install a water methanol injection system but don't tune for it, you lose power? No shit, Sherlock.

49. 

    Might you see better results running on gasoline rather than E85?

50. 

    Has no sense to use meth injection withour a tune
