Depending on how much boost the car is running, the hot side can melt stuff. I've measured compressor outlet temps over 400F on higher boost applications, Plastic typically gets soft around 100C/212F.

 

I've considered making some of these here as well, but it comes down to two paths... One is you use round tubes and modify the parts around it. The other is to make complex fabricated/formed parts that drastically increase the product's price tag (and likely not perform as well as a round tube).

The short of it is, Porsche did a great job utilizing the space there. So much so, that there really isn't any to spare.

 

I agree about not much space left in the plastic cage the tube goes through. Tial did a great job with sizing there tube for that small space. Stock Porsche tube is 58mm O.D. and 3mm thick, Tial tube is 77mm O.D. and 2mm thick. Anybody want to figure out the Flow % increase ?

 

I hope the Turbo Lady never surfaces here... (Audi forum members should know of this lady and her history)

 

Looks good!

 

Based on the pictures its not too bad at all, and nothing that will even be noticed even with the bumper off by most. Worst case if someone wanted to do this and cutting that 1-2 inches of plastics off bothers them, they can simply get a spare duct and use that when going back to stock. Great work and thanks for sharing!

 

Kuddos for doing the job yourself. That's a lot of work!

 

If one is in the mood to do fabrication. It would be a good idea to plumb some nozzles to spray water or water/meth on the intercooler while you have the car apart. You do not necessary have to plumb the entire system, however the nozzles will be in place so that you do not have to take the car apart in that area more than once. Think of it as pre-wiring your home for future audio/visual/connectivity.

 

That thought crossed my mind...may explore Meth injection once I get intercoolers as I have had luck with that before.

 

I would not spray into motor, just onto the intercoolers. Modern technology with ethanol has shown that meth injection for combustion purposes is now a dinosaur

The air path the to the intercoolers is insufficient. There is no real way to improve it without making substantial changes to the body of the car. Spraying water/meth onto intercoolers is a great way to dissipate heat if done properly. They have it on the GT2-RS.

 

When you say motor, are you referring to right before the throttle body? Can you elaborate some more? From my previous turbo experience I've found two nozzles (double up if 2 inter-coolers) one right after the intercooler on the pipe and one right before the throttle a foot or so.

 

Same here, I’ve always had the best results spraying into the intercooler pipes before the throttle body.

 

.

Exactly. Noozle in each intercooler cold pipe before they meet. What distance, hard to say, but somewhere convenient might be the limiting factor.

 

You could definitely spray on the intercoolers. That could be pretty easy to set up using an cold pipe temp sensor that turns on when the temps rise above a certain point that you set.

Question is where you would put the tank(s)?

 

Sneak peak of new bumper and light bar setup-big shout out to @Wujohn!


Because light bars are awesome!
