As I am now an AMG man and have been tweaking my car a bit I have done a lot of reading up on tuning of the 55K supercharged engine.

One thing the Americans often do is add a killer chiller system which effectively uses the A/C system to cool the charge temperature of the intercooler for the supercharger.

This is less popular here although there are some cars running it and it works very well lowering the charge temps by 20-25 degrees C.

Would a similar system work on a turbocharged system and if so why has no one done it especially given that the intercooler on Scoobs is a top mount as standard and prone to heat soak?

Wouldn't that be a nill sum game

Like trying to cool your house by opening the fridge door

Could just chuck a load of dry ice into the intercooler maybe

This is actually something I've thought about and do plan at some point to mock something up.
I also thought of somehow fitting a small fridge of some description into the bay that housed the entire intercooler. You can buy small 12V fridges so im sure one can be adapted to house a cooler and fit where the top mount sits.
It would no doubt look pretty awful but it would certainly lower charge temps dramatically.

I've always wanted to try something like this but I also want to try fitting a top mount with a front mount.. Don't ask how or why but it's something that I will try on a project in the future..

wtf is the point of fitting two intercoolers

Lmao I really don't know but I just have this urge to do so haha

How many cubic metres of air is flowing through the inter-cooler at any given speed.I would think it is a massive amount.You would need something BIG to cool that amount of airflow to any significant degree to make a difference.

Just some thoughts based on sweet fa.

2 intercoolers

some owners try shortening the intercooler pipework to reduce lag and I guess there's always one that wants to add extra pipework/extra weight etc!!


If you want to do something different with the intercooler, how about using a charge cooler system, like the mk1 Focus RS,

or chargecooler ice system, which is good for a drag car, or even a sprint car, but no good for a everyday car!!!

Agreed. This has got to be the better solution surely?

Would the the reduction in charge temperatures outweigh the power lost by engaging the air-con compressor? Probably more benificial on a big engine car such as your amg. But it just seems a lot of fiddling for minimal gain?

So you'll have the top mount sat there soaking up heat into it's mass when sat in traffic. Then when you drive you'll have the front mount doing a good job cooling the charge air only for it to go into the top mount and warm it back up.

You could also work on other cool inventions, such as.. The post air box induction kit. Where you fit a cylinder filter after the air box. You could have the std air box in place snorkelling cold air from the inner wing, then an open filter post air box sucking gob fulls of heat from the engine bay.

Or maybe the uprated walbro fuel pump feeding into a fuel cell with a std fuel pump in feeding the fuel rail?

How ever you look at it, that just doesn't not make sense.

Sounds like what some car windscreen fitter told me once.

'Yeah, I've got an evo at home. It has two exhausts. One for the engine and the other for the nitrous.'



At that point, I went off to make him a cup of tea. It was either that or punch him for being such a bull****ting dumb ****!

Lmfao. Well I don't knw how it would work but I don't know if anyone's tried it. Its something that I just want to mess around with amd see what the results are

Nearly purchaced a Mini Cooper s before getting my Wrx it had a cryno kit fitted on top of the inter cooler, I guess if it works with the super charger setup it would work on a turbo set up?

mk1 Focus RS uses a charge cooler, most people ditch them and use air intercooler!!

Yeah I guess the AMG 113 engine lends itself to the solution as it will get the approximately 10hp the A/C uses back and more because the intercooler is under the supercharger in the 'vee' of the engine where it is naturally very hot hence dropping the temps by 20 - 25C has a major effect on power output.

I think you need to understand force induction first buddy. No offense but it doesn't sound like you do at the moment. It would be like have two gearboxes! Pointless.

When I had my gt4 st205 one of the local lads off the owners club had a gt4 running around 480bhp and he had converted his charge cooler so the top clipped off and he could pack it with dry ice before using it in anger.

Can't actually comment on how well it worked but it was an expensive build by a well respected toyota specialist so you would like to think it had some sort of positive effect.

I'd say it'd even worse and actually lose power and create lag

Yes that does work, there are several AMG 55Ks knocking around with ice tank installs too.

tubbytommy

iTrader: (20)

Have you any pics or links to the setup??
Sounds quite interesting.
Do you notice a difference in power like you do in turbo charged cars on the summer ?

There's an install video here:


I haven't driven a car with it on tubby, but apparently what it does is provide more power, but also prevents the supercharger from shutting down because the air temps are too hot. I have had that happen on my car once, but I have now installed a second heat exchanger and a better IC pump so not had it since.

In standard form you do notice a difference between hot and cold days like a turbo car.

Of course with ambient temps being higher in the US the killer chiller has more application there I think.

Here is their website (a bit amateurish but it works):
