Title: Water meth injection
Post by: Mitch199024 on May 09, 2014, 11:00:34 am
I have a stage 2+ edition 30 running 350bhp, what gains would I get from running water meth injection ? Is it risky and how much to buy and get installed ? Any info would be great.

I had the AEM kit on my P1 Impreza. It was a nice bit of kit allowing to run more power / boost with less detonation & also lowering the air inlet temps. I bought a 10 litre supply of meth from jennychem & some deionised / distilled water. I had the car mapped once fitted & it allowed for another 30 horses. Obviously it depends what spec & mods you have as to what power increase you will achieve. Not seen many people in the vag world running this type of kit but then my knowledge with vag is a bit limited at the mo.

I chose the Aem kit as recommended by Alex at AKS but I'm not ready to go ahead with it yet

i agree as i was speaking to alex about a kit on thursday,but allow at least 10 hours labour

Alex at AKS fitted my AEM kit, and it took around 10 hours as stated, but he does a pukka job  :happy2:

Notice any gains from it?

Speak to Hurdy,he's running Wmi on his golfR & his previous car a ed30

Surely performance gains and costs depend on if you just going to run it as added cooling or whether you going to get it mapped in but them make sure you don't run out I guess.

Yes, quite significant, I run Revo stage 2+ and before the meth I could only run timing 4
After the WMI install I'm now safely running timing 7 and she feels far more aggressive  :happy2:

10 hours?   So ~400-500 quid to fit it?

Exactly what i was thinking. 10 hours ?  You can do a nice job half of that time.  Stick it in the passengers front bumper with the pump, cables then can go straight through the bulkhead into the gloves box or center console or even the storage compartment on the drivers side.

Anyway,

AEM for me. I can run an extra 2 on the timing advance (Revo) and have minimum timing pull. No dyno prinout tho.

I witnessed the job that Alex did, and there is no way you'd be able to do it in half the time. My whole car was stripped, including a lot of the dash.
I have the reservoir fitted in the boot with the pump hidden there as well (cut out of the material that holds the spare).  He also fitted an on/off rocker switch hidden in a compartment under the steering wheel,  and a visible green LED also below your sat/nav to warn u of any issues if the system stops working, and the main controller he installed in the glove compartment.
Trust me when I tell u that the installation is awesome.
I'm sure that you could do the installation in half the time, but it would look like a dogs breakfast, or nowhere as neat as mine.  :booty:

The WMI kits themselves aren't that expensive, it is the labour involved to fit them. Worth every penny mind in my opinion.

I was going to go back and ammend me comment but couldnt be arsed

Just want to know what every one thinks about the gains. I don't have revo software so being able to change the timing etc is of no use to me lol

It certainly helps, as for no Revo. You'll have to get custom map or alternative use APR race map which I think is 105octane.

This is to make use of the meth.

Already got APR, so getting that changed is no problem ;)

I believe its the 105 octane map. They do ask you sign a disclaimer because your technically not using race fuel.  This is knowledge from a friends ED30 with WMI/APR MAP.

R-tech will tune for WMI. See what they did with James's car here. 401bhp

http://www.mk5golfgti.co.uk/forum/index.php/topic,43854.msg624693.html#msg624693

Just shows what is possible with a K04 and the right hardware  :laugh:

http://www.mk5golfgti.co.uk/forum/index.php/topic,43854.msg518465.html#msg518465

And on JKM's rollers it made more power than some big turbo cars with an immensely flat power curve (no boost controller used here)

look what happened

wasnt this because of the high tune ?

He asked Niki for an all out tune to see what the engine could cope with. Niki wouldn't do this level of tune unless you were happy to take the risk. This is the result of 450lb/ft of torque.

It was a BWA engine which is known to only take about 360bhp with corresponding torque. A BYD/ CDL engine can take 400+bhp all day long.

I was speaking with the same guy about this a few days ago. basically the Mixture is 50/50 split to enable him to run it at the 104octane setting. does any one know if REVO have a 104 file for the "general customer"

P.S - If I go the WMI route I would want my kit in the front. this will cut half the time of the set up too  :laugh:

Yes  :smiley:

James fitted a CDL lump (see further on in his build thread) and it's happy now.

It was good of him to prove how strong the BWA engine is  :congrats:

Is this correct - a lot of guys have BWA engines make the KO4 conversion slap on meth and are fine running slightly more or so i'm lead to believe.

It's all down to the torque, that's what kills engines. 360bhp is usually known as the safe limit

Was you at BHP by any chance?

AEM recommend to only use 50/50 mixture.

Revo is just allows you to alter the the map by up the timing. I can run timing 7 where before i can only run 5. Def feel more of a kick but nothing to boast about. But for £300 its def a good mod, keeps engine temps low especially on those track days.

This is what me and my mate did, Under the passengers arch with the pump. Easy to top up  :happy2:

Cables go through the bulkhead and straight behind the glovesbox, from there you can wire your controller where ever you want to.

Longest part is the throttle body removal, very tight on the back bolts. Easy option is to get the revo pipe.

No Mate, was going to go but some other bits and bobs came up..... bloody work  :sick:

Cool - We had a few Golf owners who spoke to us about WMI.

You didnt miss much. 1 and half que to get in, some 3 hours they waited.

To elaborate. WMI is worth it as it helps keep the engine running cooler whilst making more power and torque. Even without tuning for power you will still see more power and torque. Top end power when not tuning for it is only around 5-10bhp but it is the mid range pull that impresses. More torque and power and held for longer.
