devilsown meth???

What do you reckon?.

[andyR43]

Excellent product and Bruce is a top man, He's very helpful if you have any queries.

I'm going for it as it lowers intake air temps and combustion temps

Sounds like a pain in the arse to set up and run though.

I'll sort something out mate I always do.

I looked into it, Devils own has some nice kit, the one potential scare story was malfunctioning controllers which meant the pump ran when the engine was not running, basically in this scenario the entire tank of water dumps into the intake. Obviously not great come startup with a inlet full of water.

The Devils own stuff sounds good but is relatively simple, just runs off boost which means when you hit the rev limiter, it continues to pump water/meth even if injector or timing has cut. Meth itself is combustible, so your engine is running super lean on just meth (obviously not good). I am not sure how the rev limiter comes in on the MKV.

I looked into Aquamist systems, these have more safety measures, they hook into a injector signal and only allow water injection when the engine is running and injecting fuel. They also calculate the amount of water to inject based on fuel injection rate and boost. Overall a safer, more complex but more costly system.

I was really keen to go water/meth for the ability to run more timing etc, but wimped out the more I read into it !

Simple basic reliable boost activated mechanical switch is all you need. Seen nothing but problems with the Devils Own controllers. Been running the basic 6-30 psi kit for 18 months now and would thoroughly recommend it on high boost Stage 2/2+ setups

[r5gtt]

This is what I was told.

Nope this is the 30psi boost switch model
You can set it to the boost pressure switch level so when you hit 14 psi it will spray.
Switch anything from 0-30psi
It also has an overide on and off flick switch with LED solenoid upgrade and can run it through the throttle body manifold vacuum line. D04 nozzle injector. 10 litre tank with a 30psi boost switch. complete kit.

Sorry didn't quite understand that @Dan_FR can you repeat that in simple terms please?. What's a basic 6-30psi kit?.

[Pesky jones]

Think hes saying a mechanical switch is much better then the controller. Which is your kit that you are looking at?

[r5gtt]

Thanks for that @Peskyjones this is why I'm looking at this one as I did ask the seller if it has a manual controller and he told me it's with the extra bit's in the kit. I personally don't like the digital controller as it was all over the tt forum but wasn't for me.

I know the kit for sale that you are talking about - didn't seem particularly cheap to me.

it sounds like you have the basic 6-30 psi switch which is fine
An override switch is just a 50p toggle switch, and the LED is worth about 7p
The solenoid is a worthwhile upgrade over the checkvalve though
D04 is too big for a K03 GTI, you will need something smaller. What stage of tune are you and what are your power goals?
10 litre tank is only needed if you want a separate tank in the boot instead of utilising the washer bottle in the engine bay. Does it come with all of the wiring, and all of the hard plastic meth lines that you will need to run through the car?

I run a meth kit with a 10litre tank.
Its a coolingmist kit with a boost activated switch. never had any problems with it.
You simply, set what PSI you want it to start injection at then your on your way.
I have mine hooked up to an 12v on of switch so I can run it when I want to.

I'm looking at stage 2

It's not really cheap but the seller isn't budging.

Here's the kit in a mess

[Dan_FR]

You'll probably need a D02 nozzle in that case. I have a D03 and it is a bit on the big side really.

Have you considered how you would mount the nozzle? e.g. a TB spacer, aftermarket throttle pipe etc.?

You'll probably need to order more of the plastic piping too, you'll definitely need a smaller nozzle, and you'll need a Boost take-off for the inlet manifold (which one will depend on current PCV setup i.e. standard, PCV delete etc.) That's assuming that everything else you'll need is present, e.g. nozzle holder, tank tap etc. as I can't see them in that picture
