Here we go!

How does the forum feel about stock location vs FMIC?

I've heard top mount is the way to go?





...in all seriousness OP search the forum. There are a million and one threads answering this question exactly. The answer is......we don't know.

Search "Intercooler GTI mk7 Site:golfmk7.com" without the quotes in Google. It'll bring up all threads about intercoolers for Mk7 GTIs mentioned. Are you looking for a FMIC or a Direct fit? Direct fit is all you can use if you have the front radar in the lower grille, otherwise it's up to personal preference, cost, and power goals.

lots of threads on this so storablecoma's recommendation is best. I highly recommend reading all threads about an FMIC....bring popcorn. I have one and I love reading it every once in awhile

Edit: For what its worth, I have a Wagner intercooler... its the perfect balance... super nice build quality, okay fitment, really good performance / flow and still light.... Some (like the IE) can weight over 30 lb, the Wagner is 20 (weighted it myself, not 18 as listed in that website... the stock unit is 7.5lb...)

I think you need to take that test with a grain of salt. It does not tell the whole story of how the intercooler will work.

I have the Neuspeed and I've been monitoring my IAT's for the past two years since I got it. So far...my temps always come down to within 5 to 8 degrees of what my amb sensor says. I've also always been able to hit my target boost numbers on the JB4. I saw this "test" and still picked up the NS IC.

ECS did a real test where they put the car on a dyno and actually put probes on the inlet and outlets of their FMIC and a competitor's stock location IC.

Have you actually looked at how he does the test? I have and its very standardized, he does a good job, you are welcome to show us your testing data.
How would testing an intercooler in a dyno even work man, come on.....? Because ECS did it? Unless you are building a burn out car, its the most unrealistic test out there.

There is plenty of things that make a difference with intercoolers that need to be testing, the baffles inside, slowing down the air, spreading it out, for better dissipation and heat transfer with the air flowing through the IC.... even the con of having a really heavy intercooler helps with absorbing heat soak... etc...
How would that be replicated on a dyno ? The results would be totally skewed.

Also you know the difference would be down to a few HP right? There would be scenarios where you are better off taking 25lb out of the car and running the stock OEM intercooler bc the HP increase would not outweigh the weight penalty, especially in the nose of the car.

Edit: Even an intercooler that looks good in real world tests may not be the best if they have too low flow rate... The guy from that website even did a "study" of the relationship between CFM of the intercooler and how it affects your boost.... it may be robbing several psi from your turbo... only to gain a couple of degrees better IAT, so the turbo works much harder for minimal benefit.... its all a trade off... if you are seeing IAT and not pressure drop, that's only half the story
