In case anybody else has done some digging and wouldn't mind saving me some time, I'm in the market to decrease boost temperatures, engine bay clutter, and plumbing.
So how about a small unit (fluid intercoolers that support 350+hp are not that big) plumbed directly into the cooling system so the water leaves the radiator and immediately enters the intercooler? you'd have to plumb a charge pipe from the turbo to the IC and the IC to the EGR valve, and you could stuff the intercooler wherever it would fit, like a book in a bookshelf, rather than directly in the airflow from the front end.
The I/O boost fittings on the unit I'm referring to are 2.5", and while I don't know the air volume of such a unit, but it would seem that eliminating lots of piping from a turbo to a front mount and back to the firewall again would more than outweigh the loss resulting from employing an intercooler that's a little too big for your application.
My questions are:
- has anyone else employed such a setup?
- does anyone know the temperature and (preferably convenient) location of the coolest water in the cooling system?
- how about using the hoses for the EGR cooler to cool the intercooler instead?
- how cool does the water entering a fluid intercooler really need to be, in order to be effective? obviously there's a reason they have a separate cooling system, but what if it could be done at least almost as effectively without a separate cooling system?
what do yall think? i'm staring at this 350hp unit on frozenboost.com and about to pull the trigger. anybody have any thoughts before i start dumping money and experimenting?
