Intercoolers & Chargecoolers

[Greg_S]

I know there was a thread somewhere about this but cant find it now.

anywho here is a link to autospeed about IC and CC

Autospeeds guide to intercooler and chargecooling


Also there was discussion of a chargecooler getting developed for the S2. Any news on that?

found some info on chargecoolers. Had way too much time on my hands tonite.

its about 1/2 way down. universal type

Pace products

Bus and truck type stuff

turbo terms

U'd have to be nuckin futs to fit one of these to a motorbike!

Intercoolers and some good turbo calculator things


that will do for now i reckon, nearly finished shift and time to go home at last, my bed is beckoning!

We already have a chargecooler kit for the S2 / RS2, as well as the Ur quattro 10 / 20V. One will be appearing on Martynf's Avant soon...

ahhh, the details are starting to leak out....

Sienna,

What are the possibilities of fitting a charge cooler as well as the intercooler?

I ask because, since removing my aircon, I have the bracketry in place to fit a belt driven pump of some description where the air con compresser was and plenty of space for an additional rad where the condenser was fitted.

I assume there is a limit to how cold the intake charge can be before it has a negative effect. I was thinking something along the lines of having an electro clutch to switch a charge cooler on and off depending on my needs.

Any ideas? Also, as you are a man not averse to adapting and overcoming, is there an 'off the shelf' VAG radiator that can be used in place of the twin rad setup?

Fitting an intercooler as well as a chargecooler has no benefit whatsoever, it would cause pressure drop which you don't want.
Our systems are activated by temp / boost, but an override switch is also fitted. As for the auxillary radiator, we use type 85 Coupe quattro, which is metal, same as Ur quattro, but without sdditional outlet, as on S2's and all 5 zyl type 89 Coupes. I used this setup on my S2 - engined type 85 Coupe quattro, and it never ran hot, despite the fact it was driven hard and had 426PS on tap. The auxillary radiator caused underbonnet temperatures to be fairly higher than without, due to the fact it restricted the flow of air to the engine bay, to a certain degree.

@Vagsport,

That is the right answer for the radiator old chap. I'd never checked into this before. I know that Dialynx offered a single rad upgrade like this mad from metal but always assumed it was a custom job (maybe it is), but I like the thought of an off-the-shelf part from the Type 85 CQ that removes the need for the aux rad and opens up a load of potential space for a decent sized chargecooler.

Sounds like what I'm after. Time to 'accidentally' order some more new parts Are you using the standard 5cyl non turbo rad hose without the tee for the aux rad?

As for the chargecooler, fair point, I should really think things through before I put fingers to keyboard.

How much are your chargecooler kits? I assume once you've ditched the intercooler the pipework can be a lot more simple without winding back and forth across the front panel.

Could the aux rad be used as a charge cooler rad? I'm a great believer in using off the shelf parts where possible, and not just because they cost me ziltch.

[Vagsport]

Yeah, Ben. Standard non - turbo hose off type 85 Coupe q, together with matching thermostat housing. Our kits are £650 inc.

excellent, have been looking around had had an email back from pace.

Can you send me some more details of this and any pics you have etc.

Did this project make production?, some pics would be way cool.

[Greg_S]

I havent gone any further down this route. Spending on the S2 has been cut for the moment.

Greg

[Jamo]

Shame that Greg, do the guys at V.A.G parts have any more details on the charge cooler?
If you do could you post, P.M or email them?

[rs2 jamie]

can someone help me pleeeeese? i am doing a sport quattro conversion because of a custom inlet manifold design i cant now fit the power steering pump where it would normally go . i have moved the alternator to the left hand side of the engine ( by the exhaust manifold ) looking down from the front and created space where the alternator normally goes. can someone tell me please of what model audis power steering pump bracket would fit in that space .engine is 3b 20 valve

[Jamo]

Jamie mate, think you'll need to start a new thread with this info in.
