2004 Audi TT 225

JettaRed · 04-13-2008

Here's pics of my install. 2004 Audi TT 225. The kit is a Universal Stage 2.

I mounted the pump under the airbox, but had to cut out a portion of the bottom of the box. The pump makes minimal contact with the panel filter. Using a cone filter is an alternative. (NOTE: Be sure to trim the screws on the inside of the wheel well so there is no contact with the tire!)

I ran the water feed line dirctly through the top of the washer tank using a 1/4" hole. (You need to remove the wheel well liner to access the tank.) I ran the black hose to the bottom of the tank. This was easier than mounting using the adapter that came with the kit.

I used a throttle body flange to mount the nozzle after the throttle body. The flange is available from Apex Tuning or USRT.

I mounted the controller in the little storage cubby under the ash tray. I drilled a 1/4" hole in the back of the tray to run the wires through the firewall.

BTW, you want to tap the purple/gray wire on the MAP for the controller. It's posion #4 (far right).

Nice clean install.

I've had a couple of times when really small stuff that may be in the bottom of my washer tank gets sucked up and passed through the pump. Then it gets caught in the check valve, causing vacuum leak symptoms. Here is my solution. It's a Purolator fuel filter (part no. F20011) installed on the intake side of the pump. The 1/4" lines fit snuggly inside the barbs of the filter. It will also act to catch any air in the line, though I haven't had any problem like that.

Here's an update. I finally took some logs. Basically, there total timing pull on any cylinder at anytime was 5.3 degrees! (and that was at 6200 rpm and 14 psi on cylinder 3). The graph may not be the best representation, but it's about 11 seconds and from 2500 rpm to 6000 rpm a couple of times. Anyone who wants the file, I'll be happy to send it so you. Just let me know.

The configuration is:

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
