RS2 Intercooler

[CHEN]

Hi,

I was wondering if anyone could do me a favour? I am interested in getting some RS2 spec IC (possibly for a group buy) Basically something that allows me to use standard hosing and cross member as a S2 but better. To do this I could really use a set of measurments of a RS2 IC. Core length/depth etc etc.

Can anyone help?

Thanks

The details of the core are on the forum, recently posted by Bry IIRC

I might be interested in a GB if the price works out OK. The proper RS2 'coolers are a bit pricey compared to aftermarket ones.

I'm possibly looking to upgrade my Avant to RS2 spec next year and anything that keeps the cost down to a sane level helps to make my chances of doing it that much better.

Cheers

Hi, maybe something like this??

It fits the RS2 Bumper and piping system and is bigger than the RS2.

From my point of view, internal aerodynamic of this cooler is crap . It doesn't change things when you have big turbo, crude remap and everything in brutal way like in autocross, but if everything is finetuned at the limit this will cost you quite a few horses ...

I would be interested in a group buy too.
Good luck with it

I have an RS2 intercooler with ROSS on it.

Excellent. I bet it would be a good little project, very helpful, me/Robin recently looked into re-coring one but at £190+vat for a replica core it wasn't worth it. Perhaps in a group-buy situation they could do better. But that still leaves you with the rest of the IC to fabricate & weld!

As for me, I need an IC in the next few weeks and have one reserved

I'd also be interested in this keep us updated mate

We dont care about the internal aerodynamics of this cooler. This is na example. The thought is to make the biggest possible IC to fit the Stock piping system and with the water radiator in place.

Aerodynamics look absolutely fine on this??
very similiar flow path to the original RS2 intercooler?!!!

Granted it could be made better by centreing both inlet and outlet at each end but to keep stock piping....this is the way forward

[CHEN]

agreed, I accept the access pipes dont make top notch internal aerodynamics, but I dont want to be chopping up pipes and crossmembers too much if necessary, for me its about a happy medium. I have some measurements now and will possibly be dropping of a stock S2 one as a template next week or so, didnt know there would be quite so much interest, but it should do well in getting the prices down. I will let you know how I get on.

Is it possible to make one which has an outlet on the same side and above the inlet so that the return trip within the engine bay is shorter to minimise heating?

On a related subject, when upgrading to an RS2 spec IC, is it recommended to fit an RS2 undertray to increase airflow?

Double pass intercooler's are not very effective, the air goes in then does a 180 and comes back along.
The KG series 10V (200 etc) had a double pass intercooler as stock and was quite weezy, a good upgrade was to change them for the later MC (100) single pass intercooler.
Don't go for a double, it's not worth it. You would be significantly better to move the inlet manifold to an AAN style if you want to reduce the inlet tract.

On the RS2 undertray question - I think that is a valuable upgrade whatever IC is fitted. Of course you could just modify an S2 undertray to get the same effect (if not as pretty).
