It seemed a no brainer to me that a good w/m injection kit would provide high octane fuel and reduce cylinder temperatures for virtually free after the initial outlay also it steam cleans your combustion chambers reducing burnt deposits causing hot spot on valves and cylinder heads, I opted for the tuner kit which is controlled via my link ecu .


A few rubbish photos of the install

Looks good! It's crazy how easy it is to tune after water/meth...so long as the system is working you just won't knock. I quit making power on the dyno when I was tuning before I knocked on timing adjustments at least. I was getting some stubborn/persistent LSPI as boost came on that I couldn't tune out and then after meth it never knocked.

Do you have an alarm or anything to alert if the pump stops working or nozzle clogged or tank empties?

 

[Lockheed]

its got an in line flow sensor and float valve , it will revert to normal map if triggered .
ill post the rest of the pics and results I f there is any more interest .

 

[TMX]

I would be interested to see more pics

 

[Lockheed]

@TMX that gives me licence to go mad .
Ive got a lot of pics and data that im putting together for your perusal .

This is something that I have been interested in (along with / or) an IC sprayer.

Considered this on my last car but decided against it, meth is really nasty stuff and didn't want to have to worry about it in the event of a prang or have it in the cabin as loss of consciousness, blindness, coma, seizure, or death are the risks associated with long term exposure from leaks. Just inhalation of four ounces causes irreversible damage to your nervous system. :surprise:

 

[theshootist]

Very interesting! I have a friend running a methanol system on his BMW 335i, he rates it.

So you're using it to help the engine run better rather than for power? I presume that you can use 93 instead of having to keep finding Shell stations for 99?

I've been researching this for months and have fail safes in place as stated above.

Don’t get this

Methlylated spirits is around 5% methanol and I don’t see french polishers dropping dead across the country...they use vast quantities.

Sure, methanol isn’t very nice, but the stuff coming out the back of you car kills a damned sight more people than methanol....and 10 gallons of hydrocarbons pumped all around the car every few days doesn’t seem to worry most people.

Methanol is just another kind of alcohol...bit poisonous, so don’t drink it. It can make you car go faster.

Health and safety’s gone mad these days......

Forgive me for asking what may be a bone idle question - but what is the purpose of a water/meth injection kit, and how exactly does it work?

 

[DragonSubie7]

@lockheed - So it sounds like you are using the system so you can use lower octane gas without knock.
Parts and install cost aside, does the ongoing cost of the methanol you burn outweigh the cost of the higher octane fuel?
Have you determined approx mileage you get out of the alcohol you are using?
Are there any corrosion issues ?
Have you noticed much difference in performance/mpg/etc.
Are there any issues related to getting the car to pass emissions testing?

Would I be correct in thinking that Methanol is what I used in my Mini Cooper S all those years ago - if I recall correctly I added 1 gallon in each of the 5 gallon tanks.

Methanol has a higher octane level which allows you to run higher compression and more aggressive ignition timing for more power, especially on forced induction engines. In the same way it can be used as an octane booster for lower octane fuels that you wouldn't normally use.

It if you were to run the same compression with petrol then you might get diesel like detonation during the compression cycle.

By squirting in some meth or water, or water meth mix, you also cool the intake gases. So the cooling can also increase power. It also can lead to a cleaner engine apparently. The BMW M4 GTS has a water injection system as standard. You're also reducing exhaust gas temperature, which must help the turbo stay cooler.

My mother has a Cooper-Alta race car from the 1950s which was originally made to run on something called nitro-methane. It now runs on pure methanol because nitro-methane is hard to get hold of and I suspect a bit dangerous! You have to be careful with methane anyway because it burns with a clear flame. She buys it in fairly large quantities.

That's all I know. I want to fit it to my car!

Reckon that would have probably been avgas, Kevin. No sure if you could add methanol at a 5:1 mix without having to retune the carbs. Avgas would just require a timing tweak to get the most out of it.

I'm in the process of putting one together on my FSti - so far I have mounted the tank & pumps in the boot (using OEM Impreza STI intercooler spray tank) & have run the lines & cables to the front.
Intend on injecting a 20/80 methanol/distilled water mix. I'm using it in combination with the 09+ Impreza STi 'wide' TMIC. Main aim is just to keep everything safe & reliable once I have it remapped.

I'll try & put together a thread once it's all done.

 

[Lockheed]

So this is the final fitment of the tank and the pump .

I bolted it to the rear strut brace as I didn't want anything that couldn't be undone note the tank is above the pump as it is a push pump .
The car now is at the Mappers waiting for the final tune , I don't know what the final result will be im guessing 15%more POWER
Ill still be running 99ron fuel ending any speculation of running normal pump gas .

For anyone that's interested ill be posting before and aft figures and whats been done in the engine bay regarding check valves ,pulse width modulating valves and injector nozzle sizes.

A lot of this knowledge has been acquired from NASIOC forums as there is piles of info on w/m injection .

 

[theshootist]

Great stuff. Looking forward to seeing the results

 

[Lockheed]

This was done on a Dynapack hub dyno so the variables associated with rolling roads are eliminated Abbey say there is approximately 100hp difference between their system and surrey rolling road on four wheel drive car .
Here is a sneak preview .
Main switch turns on system when the following parameters are met:
40% throttle
1.2 bar boost
4000rpm

Water/meth also triggers a higher boost map to 1.9 bar .:surprise:

If the water/meth level drops below the float switch to the point where it opens it turns off the w/m injection system and lowers boost back to normal high boost.
Totally automated
Also if the flow sensor detects low flow it will also turn off the system .


By the way @theshootist your Mum rocks for having a methanol powered car:Banane08::Banane08:

I don't know the details but i do know when I tweak my Nitro RC cars (Nitromethane/methanol mixture) in the garage with engine running, even with the door wide open after a few seconds i have to get out of there or it feels like my eyes will burst into flames. Yup, the stuff is hazardous to be around at least post-combustion
