water/meth injection

[Scuby_snax84]

I think if an injection kit is laid over a normal ECU tune, then it's fine to run it dry.

Do you think you would still see noticeable gains running w/m on a normal tune? I’m assuming if you had your car tuned to suit the w/m you would see more gain. I queried a tuning shop on the use of w/m and they said if you have a good intercooler there is no real point in running it. Thoughts on this?

You should see some gain. The hotter the weather, the more gain you will see.

The more boost/ignition etc/cylinder pressure you start to develop, the more gain you will see. Basically, the more heat you are removing from the charge, the larger the improvement.

I see in your sig you are quoting 200wkw.. At that sort of level you should see an improvement with water/meth injection. Don't expect 80hp, but you should see a noticeable improvement.


You won't see and negative effects unless you run a far too high dose and the engine runs pig rich..

I thought about going down the path of water/meth but i heard too many horror stories of blown engines and even witnessed a burnt out bmw 135 caused from water/meth. From what i hear you need to make sure you tank is always full, if you run it empty with the foot flat it could end in disaster.

The "danger" is in an aggressive tune that expect the higher octane rating, lower charge temp/EGT of the water/meth injected intake when driven at high throttle and loading. As Greg says, a float to indicate low mix is a simple indicator of when to back off and maybe switch tunes. If the warning is ignored and engine gets cooked, then that's the driver's fault (same as hammering on 92 octane fuel with a 98 octane tune).

It also helps keep the intake side clean, especially with direct injection engines.

Here's an interesting development from Snow, something I found after a recent event has renewed my interest in meth kits. Bet it will get Preeny's interest. No, I won't be trying it in my poor TDI....my kit has been donated to a "greater cause", I'll have to save up for another one.

That would probably be in the range of 3-5%, I would imagine. I'd be very wary about it. Nitro is like your mate's rottweiler.. Sure, you can have good fun playing with it, but if you don't respect it, it'll bite.

Also, Nitro's very corrosive. When you pull apart a cast iron fuel engine, there's a lot of surface rust on things. It also pits the bores if left to sit without flushing. You even have to service the fuel pump after every putting with oil to stop out seizing.

I would only use water-meth if your chasing that last bit of HP . If your intake air temps are too high either get a better intercooler or lower the boost .

Preeny , has someone hacked your FB account ?

Very valid point. However, if you want that bit extra and don't want to have to increase your intercooler size etc etc, this is a viable option I believe.

Yeah I left my phone on charge in my toolbox and I recently removed the screen lock. That was a mistake. Haha.

Just to let everyone know, that all this talk should be referenced for "Off road use only" - Water Meth (or any alternate "fuel" system) has to meet the requirements of ADR 17 & be engineer certified for street use.

There have been plenty of cases of defects happening, and it's pretty hard to get them engineer certified in all the Eastern states at the moment.

If anyone has some good examples of legal engineered installations, this would be a good reference thread for all those trying to do an installation.

Valid point, Guy.

I'll speak to my Automotive Engineer friend and find out the details of legality for road use in NSW.

I installed a Snow performance kit on the M5 when I put the supercharger on it in May 2011. My primary motivation was simply to eliminate the risk of detonation, but the fact that the ESS supercharger kit that I used doesn't use an intercooler means the water/meth made a huge difference to the power output, from 316rwkw with no meth, to 350rwkw running meth.

The snow performance kit is cheap, and very configurable. Methanol is cheaper than petrol (about $1.10 per litre), and you use so little of it. I've done 20,000 kms since installing the kit, and i've used a grand total of 25 litres of Methanol (so 50 litres of 50/50 water/meth mix. I have a 12 litre tank installed in the boot, I just top it up once a month or so. And anyone here that knows me will tell you that I am not a sedate driver.

Admittedly, my circumstances meant that meth injection was perfect for me, and most other people aren't going to get the same benefits that I did, but one thing is for certain, any performance car that I won in the future will have a meth injection kit fitted as one of the first mods
