Do a lookup of the rallye. It had the same setup for the shrouding and whatnot. I'm pretty sure it had the same intercooler.

Umm yeah, the rallye has a totally different intercooler.

The GTD is GTD specific. It sits near the battery and is oriented face up.

Although, if you can get a rallye intercooler, that would be even better, just make sure you are planning some serious boost to make it work.

Try looking at www.ebay.de and look for "Ladeluftkuhler". Unfortunately, I dont know how to make the umlaut (sp) for the second "u". You will need to have that for a successful search.

I'm selling one from a GTD.

No shrouds though - the parts are obsolete to.

The RA/SB IC looks like the GTI G60 one with air cond.
The Rallye has an FMIC or SMIC (don't really know the exact setup).

Is this not the same setup as the GTD? It's a quote from vwvortex's featured car "the color of money" http://vortex3.rely.net/artman/publish/article_313.shtml

Quote

The component that really sets this engine ahead of other G60s has to be the VW Motorsport intercooler and air duct that was originally developed for race spec Rally Golfs in the late ‘80s. Since the piece was developed as part of the factory Motorsport program, the fitment is clean and looks as if it was there the day the car rolled off the assembly line. Air is intended to flow under the driver's side headlight and into the duct, though NGP chose to improve on that by fitting the car with a custom fiberglass hood with built-in air scoop.

Oh, and where can I find one?

There are a few things wrong with that.

The intercooler is from a GTD. The car is not even a rallye.

If you would like, I can take a pic of the Rallye Golf intercooler that I have sitting on my shelf. It is about 2.5 times the size of the GTD unit. It is a front mount unit that sits in front of the radiator.

It seems that someone says they have the intercooler a few posts up.

I really don't know where did the man get the "Motorsport" idea. :?
That's a G60. It's the stock IC from the air contitioned versions.
It just happens the IC looks pretty much like a RA/SB one, but I belive they are actually different. The inlet and/or outlet is the difference. :idea:

So,... it's not.

805c and 805d

You are correct sir. I must say that they look very similar. However, I would be very curious as to how the AC models utilize the cooler that I have and swtill have space to fit the condenser.

I would be more apt to believe that the IC in the pic is one used on models that HAVE AC.

either way, thanks for the info! Learn something new every day.

Group buy?!  I'm in!!

I've been looking for a while.  I'd really rather buy the whole works so its a bolt on deal.
Below is some stuff I googled up a while back:

Looks like a fatory parts diagram, no numbers though:
http://www3.telus.net/greenough/images/gtdicdiagram.jpg

A2 GTD intercooler is 11.5" wide, 2.5" thick and 9" tall. The part
number is 191 145 805A and it is manufactured by Langerer and Reich.

I've got ETOS here with all the part numbers on it - which do you need?

GTD intercooler is standard type, and G60 is crossflow type, that is the difference...

Title: GTD intercooler
Post by: RabbitJockey on May 20, 2006, 12:16:36 pm

i wonder if standard or cross flow is better,  cross flow probably flows much better...

Post by: RabbitJockey on May 20, 2006, 12:18:30 pm

oh, lol i read on a site off google, definetly cross flow, maybe i'll use my passat intercooler instead of my audi 4k or 5k one.

Post by: entuzijast on May 20, 2006, 07:51:26 pm

Crossflow is better and I don't recall see any aftermarket IC in standard type....

after going into the intercooler, where the hell does the air go?

Title: GTD intercooler
Post by: burn_your_money on September 10, 2006, 04:56:55 pm

into the intake manifold

I really hope that was a smartass comment :p

the air coming in over the headlight across the intercooler appears to dead end right on the engine, not really what I'd call ideal for flow.  Not to mention the heat soak issues.

The air would dump into the under hood cavity above the transaxle, which should be a fairly low pressure area. I expect the pressure differential across the core would be much same as a front mount, though the core size is much smaller. The heat soak issues with the GTD setup are real though.

 I run a similar setup to the GTD's on my Mk3 but it uses a thicker single pass core and a larger intake duct. The effectiveness is decent. Its difficult to get IAT's above 40ºC with 17psi of boost. IC inlet temps can exceed 115ºC.

There are many ways to mount an intercooler, the front mount allows the largest physical size but may not always the best for airflow, especially if you have AC condensor, IC and rad all stacked up. Some world rally teams mount rad and IC angled in sort of a V shape to avoid the pitfalls of layering, requires lots of sheet metal work and an "extractor" hood. I've always thought that the the twin side mount with vented fender linders from the audi TT might be the hot, er cool ticket for an AC equipped car.  :D
