As requested - Here are is some of the information we found when researching the Golf R intercooler:
4 more bars spaced more closely together
* More equivalent frontal surface area, as well as internal cross sectional area - improved flow capacity
The plate design inside the bars are more closely packed
* Improved efficiency due to greater rate of heat transfer
Smoother flowing end tank ports
* Improved flow characteristics compared to the S3 fittings which have steps in diameter causing turbulence.

Interesting, so you'd say the R IC should perform better than the S3 intercooler? Everyone suspected it was more efficient, but no real proof.
It's also heavier as a result.
Curious if meth + R IC is a winner. But then again, you see folks with a Golf R upgrading.

They are indeed both VW/Audi part numbers
Here is the S3 http://www.deutscheautoparts.com/View/1K0-145-803-P/0/39072
and Here is the Golf R

Please feel free to take a look at the pictures for the design of the tanks. Hope this helps

You can make more power, but the case here is more for repeated power. As you may know, an ideal gas undergoing adiabatic compression will heat up significantly (as the turbo compresses the air). This reduces the density, so the intercooler, as the name implies, cools down this air in part to increase its density. That's probably why the Subies could make more power with an IC.
Now it is true that over time an IC can get hotter and hotter from repeated pulls, and that's primarily what we are considered with in the GTI. Eventually we suffer from heat soak, and the ECU cuts a ton of boost and power to reduce the temperature of the air going into the intake manifold. Even before heat soak, you can lose considerable power just because of the lesser density of the hot air.

I had the S3 IC on my GTI and loved it. Does it give you "more" power? No. What it does do is allow you to use more of the power you are making for longer, especially in hotter climates where heat soak will rob you of power quicker. The IC is not something I have ever heard of VW pitching a fit over, especially ones in the stock location. I prefer the S3 with metal ends vs the plastic R IC but other than that they are virtually the same.

Im sorry I dont have any infor on performance of one VS the other. I dont know if anyone has done dyno testing to provide such info. The aluminum tanks are obviously higher quality and base on the design they appear like they may flow better. That is just my opinion though,

Personally I think the I/C on the GTI/R is one of VW's Big Time F* Ups. What rocket scientist that works for VW decided to put an air to air I/C in between 2 other heat displacing radiators??? STUPID!!
Personally only I/C I think that is worth a S*it aftermarket wise is the Nuespeed Front Mount. Its actually A FRONT MOUNT not just another bigger I/C sandwiched in between 2 other heat sources.
Will improvements be made with an S3 or others sandwiched in between? Yes. But get your car on the track and I am sure heat soak will sit in allot quicker than the Nuespeed one.
IMO the Nuespeed one just makes more sense.
VW what were you thinking??? :mad0259:

Packaging constraints and damage claims, probably.
