When my car was running it did that as well. Before the W/M kit was installed I was spiking about 16PSI or so and then once I had the W/M kit in I was hitting almost 20-21PSI. The car went into a soft limp mode a few times because of this. Then thats when everything went downhill from there.

so the lesson learned here is because of the increase in PSI after installing water/meth good idea would be to turn the boost controller down a little...to account for the extra increase

 

Yup! +1 to that!

And if you don't have a MBC you can use lemmiwinks or uni to turn it down.

I think I found my sweet spot. Here's the setup:

GIAC-X
Forge 007P DV
BoostMachine Max Boost: 20 psi
Timing (via Unisettings): +3 degrees
Nozzle: 3 gph at throttle body
W/M onset: 5 psi
W/M full: 15 psi

I actually reduced by max boost from 22 psi to 20 psi. I may add another .75 degrees of timing, but maybe not. The car runs really strong now.

 

You should run some of the butt dyno logs in VAG-Com then post your rough HP numbers.

I plan to.

Have a HKS SMF filter on the way, figure I'd get a baseline, then with the filter, and then with the water/meth as well.

 

Paintball,

How's your car?

Long Process.

sounds pretty wild. gotta laugh, a few guys there were saying how overwhelming it all looked, but if you focus on what your goal is, its very simple. Yes, theres piles of wires and hoses all over the engine, but none of them matter, its all coming out as one piece.


Keep at it though, the satisfaction of finishing it yourself always outweighs the trouble you went thru to get it done.

 

I moved the nozzle to the top (instead of the side) of the intake. That seems to have made a little difference, but could be my imagination. The throttle plate opens towards the manifold at the top and away at the bottom. This may give the water more dispersion. Spraying from the side limited the air to what was coming from the bottom of the plate.

I've used water for many years, since about 2002, and I've never had the type of performance increase that I am getting from this kit. It probably has to do with the timing advance and the progress amount of water being sprayed, but I can feel it. At first I was calling Bullsht to claims of 20 whp, but maybe I was wrong. I'm not a big dyno fan, so I'm not getting her dyno'd. But this is definitely a nice, affordable next step to take in performance mods.

Oh, and how's the S4 coming, Paintball?
