Intercooler Vs. Chargecooler??
garage19 - 12/10/05 at 10:33 AM

Due to lack of space I'm having problems with fitting an intercooler in the front of my zetec turbo Indy.
Currently have a 2wd cosworth IC that I am making new ends for.

However it has been suggested that a chargecoooler setup could solve my packaging problems.

Has any one had any experiences of running a chargecooler? What are they like compared to an IC with cooling effeciency?

I was thinking of running a motorbike rad sandwiched to the fronof my main rad as a pre-rad and making my own CC by putting a water jacket on an existing IC core.

Does any one know if there is a difference between an IC core and a CC core?

Any ideas on a reasonably priced 12v water pump?

Cheers,

Doug.

More info' on the WSCC site. They're having a discussion on this at the moment, see the link below;

A few mates have used charge coolers on GT turbo’s and the charge temperature has come right down. They also used a separate header tank and pump, this will add weight and be something else to find a space for, care must also be taken with positioning as you do not want to make the boost circuit any longer than necessary. If I remember correctly ‘Hicost’ used a 2wd cossie cooler mounted along the scuttle, looked neat but would need air ducting through it! Pace products are the people to talk to for custom coolers and stuff.

Could you package an intercooler at the bottom of the engine bay somewhere with a simple scoop to feed air to it? I'm not familar with what sort of package space you have with a car engine indy. We did something similar with a radiator on a formula student car when packaging was tight...? I was thinking maybe just behind the steering rack if there is space or in front of the passenger footwell?

Someone who knows car installs can probably rubbish my suggestion.

I allways thought that Charge coolers or what they call over here water to air intercooler, was normally more suited to drag racing where it could do maximum cooling for a short time and then heat sinking was not an issue as you were shutting down. Would not water or even better alki injection to chill the charge be less work and also allow a hp increase.
I supose it also depends on how early your boost comes in as well as any off boost time will recool your air to air very quickly.
But then again I may very likely be wrong.

Water injection can be used for charge cooling, but the vapourising water displaces air, so ultimately limits power.

I thought that the oxygen in the water actually helped in that respect, ie for the same volume the water vapour was more oxygen rich than the same volume of air and since its actully done after the air compression the actual cooling effect allowed for a denser charge to be forced into the engine ie more power?

hicost ran a charge cooler but has since changed back to a larger intercooler mounted in front of the rad, i believe its ok (though prob not ideal) to have an intercooler and radiator using the same air in the nosecone..

Ned.

ps i appreciate the packaging may be easier but surely the weight would be higher carrying round more water, a pump to circulate it and another rad to cool the water?

Whilst on this thread, I'm unsure the rad on my Stylus will cool the 200sx motor. Rather than spending £££ on a three core rad, is there anything stopping me putting another identical rad behind it (there's loads of roam) and running them in series?

BTW - a good source of intercoolers are the old ones from Nissan GTi-R's, the tuners bin them in favour of larger front mounted aftermarket ones, and they can be picked up for peanuts - I've just been offered one for £30 delivered!

nothing what so ever - i read a thing on this a while ago but using rad and intercooler - basically the first will heat the air, but not to the same temp as teh water so some cooling will still take effect. You'll also have the advantage of more water in the system so more cooling capacity (but extra weight)

i managed to fit a rx 7 intercooler in front of the rad on my old westfield and had no probs ,ran 1.5 bar and even after a real good thrash the intrcooler was cold to touch unlike the cossy intercooler when it was still in the sierra , i think if you can get it in the nose use an intercooler.

From wikipedia (http://en.wikipedia.org/wiki/Intercooler) it appears that the charge cooler uses water to cool the charge, then cools the water in a separate radiator.

So the difference between the two cores would be one runs water, one just sucks air.

[edit]I think this may have already been said, but the wikipedia link still might be useful[/edit]

Jasper,

what rad is installed in your Stylus and what power are you looking at? Due to the (thankfully) large nose area, Fury's and Stylus's (Styli?) have a large choice of Rads to choose from.


Jasper - 18/10/05 at 09:33 AM

Power will be around 250-280 bhp and I've no idea what the rad is as I bought it part built. It's brand new, but it's not very thick and half the size of the one that was in the original Nissan 200sx the engine came out of..... that's my worry. I may just try it and see....

Jasper,

You seen this MK thread?
