Water Injection Setup for Golf R
Hi guys & girls,
Just thought i would share my water injection setup with you. Although i am only running Water you can run Methanol if you wish. Photos first, information after.
Ok so my setup consists of 2 nozzles. 1 smaller nozzle is placed just after the intercooler. I drilled and taped a hole in the intercooler outlet pipe and fitted the nozzle so it was flush with the inner diameter. This nozzle dramatically cools down the air going up the uptake pipe, most importantly it feeds the intake air temp sensor the information we want which is that the air is now super cool. This then tells the ECU "hey man its cool to run all that timing/boost we tuned into it".
The 2nd nozzle is placed in my specially made throttle body spacer. The best bit is i have made 2 different types. 1 for snow performance nozzles and 1 for devilsown nozzles (yes they are different) Anyway now my plug is over back to the story. The 2nd nozzle is larger than the first and this really feeds a lot of water/meth spray into the intake manifold which is fed down through the head into the cylinders. Note that having a main nozzle before the throttle body is not a good idea (some after market uptake pipes have a position for them) and it can damage the throttle body butterfly assembly and cause it to fail. Also note that i am using the stock uptake pipe.
Now i have nice cool atomized spray (super fine mist) going into my intake manifold. This dramatically reduces heat inside the cylinders. (up to -300degrees, "apparently") Protects pistons, gives more consistent power, more power by enabling you to run a lot more timing and or boost. (more power) on a stage 2 Golf R you can obtain up to 28awkw more just be running a similar setup.
The tank. 8.5 litre race tank. Baffled, 250psi pump attached to it and i have installed a float level sensor so i am warned on the controller when the level is getting low. How is it held in? With a custom bracket i made to hold the tank in place, this sits on top but is floating on the floor of the boot. I can still get my spare wheel out etc. Winning. How noisy is it inside the cabin? WELL, i cant hear it at all. It makes no noise.
Controller: Progressive boost controller. I have mine set to start coming on around 8psi which it starts feeding at about 20% duty cycle. Then by 20psi it is at 95-100% duty cycle and stays on 100% until the throttle has been lifted off or boost goes below 8psi. Power light, pump on light and level sensor light so its a fairly safe setup.
All in all i think this is a very neat and tidy setup. It serves its purpose perfectly and is a good value for money upgrade for anyone with a low to heavily modified setup. Especially in our hot climate.
Cheers
