I am helping a friend install a turbo on a 2g eclipse when i was looking at the intercooler i was wondering if you could turn the intercooler for a turbo into a sort of precooler for a roots charger. now my idea is weird but i think it might just work. As all of you with chargers know heat soak sucks now what if on one inlet of an intercooler you put a filter and the other end you run to the throttle body, now it would restrict intake air flow just a little BUT it would durasticly cool the intake temprature wouldnt it?
lemme know what you guys think about this.

Wouldn't cool it any more, since all you're doing is sucking in outside air. The reason intercoolers cool air is because compressed air is hot, and running colder outside air through it cools it down. Well if you run outside air through outside air, its not going to do anything but restrict the flow.

Buy stuff from CarCustoms Ebay! Won't be disappointed!
if you're sucking in ambient air, and cooling it with ambient air.... you're just going to get ambient air... Well not really, the speed of the air passing through the intercooler MAY cool the air charge somewhat, but any gain would probably be undone by the restriction the intercooler poses.
The only way to use an air/air intercooler on a roots setup is if the charger system is set up like the Jackson Racing Miata supercharger... where the charger doesn't bolt to the manifold, but bolts over the exhaust side and uses a pipe to transfer the air to the throttlebody.

Or you could do it like this!
Thrasher Charged
uses a pump to cycle the coolant from a front radiator to the heat exchanger under the supercharger.

hmmm Yeah i guess it would kinda be defeating the purpose to use it lol. then where would be a great location to run my intake so it gets coldest possible air?

the idea of using a separate cooling system for the housing is one that a couple of us are working on on BCJ. not totally sure why but the housing on my S/C even under some spirited driving doesn't heat up at all but i still want to design something for the long run.
boostcavy, another thing is that when trying to suck air through an intercooler, it sucks. you get MAJOR restriction and very slow response. now, when you have a turbo or charger thats FORCING air through the intercooler, its much easier.

what extra opening does the eco charger have that the gm chargers dont? ive never seen one up close to see.

Not true.
Just look under the hood of any 89-94(?) Thunderbird Supercoupe.
But it is true to say that to do similar on anything J-body related will take some major and skilled fabrication.

The charger and intake aren't one piece like they are with the LD9 blower. There's a set of coils (best way I can describe it) between the charger and the intake where the compressed air passes through, and it gets cooled. I believe it's air to water? Not sure. Anyway, that set of coils has coolant running through it, which is part of a pressurized system independent from the normal cooling system of the car. It runs a 50/50 mix of Dexcool/water.
The new V-series 4.4L supercharged Northstar engines have a similar set-up.
This video should pretty much show exactly what I mean. Everyone should be right-click-save-as-ing this!!!
