Methonol Injection

The average increse with no proper tuning by somebody who knows how to tune with meth is a 10 % power drop.


With tuning you could gain 25 % ish

There is a surprising lack of knowledge on this thread

well I saw a power increase without changing my tune at 1 BAR on 50:50 but hey what do I know !! :rollin I only improved my terminal speed by at 6 mph at the quarter mile at 1 bar, must be due to my surprising lack of knowledge

i dont see it as suprising, its a car forum not an astro physics forum....:Nono!

anyway some of us dont need it:burnout

[BlitzBoy]

The times when people see power decreases is when they are using pure water and no methonal and the water is quencing the engine eg too much water is being injected

some good discussions on this link and some mis-information dont take all what they say as gospel

Re read this in case there was something I missed - don\'t see where the \'surprising lack\' of knowledge is - perhaps it was just a lack and not that surprising, perhaps it was just surprising, or perhaps you were after war and peace on this.

From my read of the thread I got:

1) A lot of people tend to mix Methanol and Water in 50/50 quantities
2) Both Water and Methanol will offer cooling of the intake charge, but water will offer more because of the higher specific heat capacity
3) Methanol in the water will help prevent it freezing in the pipes when the weather gets cold - particularly for boot mounted tank
4) Methanol is combustable, so it will by definition improve on the burn as compared to just water on its own
5) Methanol can be obtained from Race fuel suppliers
6) Blitzboy has real world experience of power gains with Methanol/Water and without having mapped for it.
7) There are two references to info on other sites

If you think I am having a pop :Grrr - then perhaps I am - your comment wasn\'t helpful, seemed to be coming from the I know better school - but I wont tell you, and lets face it there was genuine interest in learning something here - if you want to join in then FFS contribute something without coming over all elitist.:p

It\'s a forum - people discuss things - folk are at different levels of understanding - some have real world experience - some have good book knowledge - some have both - but the idea is to contribute and make all our lives a little better.  :cheers :driving

And finally another contribution  :

If you were getting a loss of power running WI (with or without meths) then you could be quenching the flame front too much or have a weak spark that is less able to ignite the mixed WI+Meths+Fuel+Air mixture.

The amount of WI+Meths injected and the boost point at which it is introduced might be more critical than changing the fueling for power gains / losses.

Well said that man

Yes its a shame when the keyboard warriors hide behind a fictitious name and location. We must apologize for some of the idiots that come on the forum Rotary Menace but on the whole they are in a minority.
Sway2003 shall we edit your location to read northampton area?

Lol, you would think people would have better things to do.

Anyway, I have read this thread with interest as hopefully I will be going down the WI route - have decided on 50% 50% mix and I want to map for it

Know one as said anything with an attitude to that I know I think I ask a good valid question.


Hey i tell you what I’ve been a member of quite a few forums and this is by far the best although I don’t actually know that much (besides how do you know im not knowledgeable i could be fifty and be all knowing) i feel that i can contribute and discuses without being flamed as well as asking all the any question that pops in my head (very few do that i can discuses here)

Neil ask away thats what the forum is here for! Prof summed it up pretty well any power increase is all in the tune most people are at the moment just using it as a safety margin rather than pushing the envelope but it sounds like there may be some more aggressive tunes about next year.

Your all A+ people thanks.

Right im off for a few beers

[richard cash]

no ones mentioned this but what about mixing methanol with fuel? i dont know what ratio would be needed to be effective but surely this would mean theres no need for a seperate water injection system. The only draw back i can think of is some will be wasted as you wont always need methanol, say when driving round town etc.
