Will this intercooler fit?

[kaanage]

On the subject of intercoolers, there is some excellent information on design & construction here:

ARE Cooling

ARE have been around for a long time & have built some prototype stuff for us over the years, they also initially worked with us on resizing & testing the APR core for the 9N Polo (unfortunately we discontinued it due to lack of demand).

Well worth the time to read it.

Great link!!!

The Configuration sub section of the Tanks area shows that ARE don't consider the SEAT style layout (180 turn at the far end tank) to be sub optimal.
In fact...

The other design mostly is used in the USA., where tanks are on the top & bottom of the core, causing the charge air to make two 90 deg. bends. By using a second manometer with a long thin probe, we found that 80% of the intake charge flows through the end 25% of tubes on our first test tank, which was of reasonable length. Flow rate was good but cooling rate was terrible. When we doubled the length of the tank, 55% of the intake charge flowed through the end 25% of tubes & overall flow dropped 9%, indicating that this design has too have very long tanks, but should be able to be avoided anyway

A dual pass intercooler is heaps more efficient where both pipes are on the one side, but they require more height for the core.

But it looks like it all depends on the execution of many fine details that are dependant on many factors of the individual installation.

Whatever can be gleaned from the dyno day on this subject will be most worthwhile.

I bit the bullet, getting the Seat cooler

I was interested in the THS cooler, but they didn't respond to my message through their site and the costs we've been calculating in this thread were based on being able to use the discount code which seems to not be applicable (so the core is about $600 if you get it through Paypal). $60 for the brackets

Seat Core with brackets and postage to Sydney burbs is under $500 from Darkside Developments website (cheaper than their Ebay store)

-edit- already contacted by darskide, great to deal with.

Good deal.

And good find!! I've been on that site heaps looking at stuff but never looked at the 2nd page of the inlet parts
Ryan's pretty good, isn't he

Found some interesting piping options, the hard bit with the Seat kit is the MAP sensor relocation.

Kinda hoping this will help me on the S3. 2 diameters available.

Nice, would we need to keep the OEM diam of the piping for this sensor, like with the MAF?

From a physics point of view, we are just measuring temp, so the diameter doesn't make a difference that I can see. Going bigger will increase volume in the system (insignificantly) and maybe it'll be harder to integrate with the pipework you have?

I ordered this:

Have someone weld it on for you in the correct placement. If you copy the forge installation kit it needs to go on a 90 degree curved pipe and then you don't have to re-route your cables.

Yeah, trying to avoid the local issues...
I'm working on a kit, so if this solution appeals to you but the effort / engineering involved is too much, I'm hoping to have one of our local forum members offer all the components (including the MAP sensor in the elbow) available for around the $250 mark. PM me if you are keen.

$750 for the Seat cooler and piping kit - Winning combo

Thats about what mine came in at.
Ths Seat sport intercooler: $483
Pipes off ebay : $254
Brackets from Seres $60
Just under $800 for what seems to be the best value for money intercooler.

not sure if it will fit the polo but in the uk they rave about the welly intercooler for the a3/mk4 gti

[Stuwey]

Why not just buy this??
