Default Closed cooling systems for 750-950 hp, intercoolers, sear strainers etc

Who has reasonably priced exchangers efficient enough to run something like that?

How are you guys setting up intercoolers for procharged type blower systems, with its own exchanger system in a closed loop for cooler core, or seawater with seperators(sea strainers)? If anyone is doing closed loop intercooler systems, what about use a larger exchanger than you would on just motor to do both systems? I was thinking about longevity of intercooler cores in a Eaton type blower that you cant easily replace, how are the intercooler systems done on the CTSV supercharged LS engines used in boats?

Many intercoolers draw seawater off of a transom pickup completely separate of the engine cooling system. It keeps the air from getting too chilled at idle as well.

Air too chilled at idle? How is that even a thing? (Unless your talking about old carb stuff... we routinely run our engines with intake air temps in the 40 degree range with air/water intercoolers)

I didnt want to pump seawater through the intercooler bricks inside of the factory LSA blowers, they arent all that easy to replace

pro charger uses water from the sea pump,not from a seperate pickup.on an m4 or m3 they use a -8 line.i always thought that was not big enough.

It's better to use a sperate heat exchanger with a small electric circ pump. The coolant in the engine exchanger will be too hot to adequately cool the air. The exchanger for the intercooler doesn't have to be huge, I'll post a couple pics of the stainless ones we use for a reference.

This is what I have cooling 800hp Procharger motors
http://www.standard-xchange.com/tool...ntend/item.asp

I run coolant in the block and my intrecoiled runs off the seapump.

Ever get a chance to drum that up?

I see air/water Procharger cores. So your saying you pickup seawater and run it through the exchangers you linked to (which size ones if so and what pre/post inlet temps do you see) and then have water/coolant circulating from the exchangers to the procharger A/W cores?

Osco used to do custom heat exchangers. ,even dual core, for running your coolant to and from the intercooler.probably wouldnt fall into the budget category though.

Sorry, forgot about it. Here's the size for an LSA, 2/3 is the exchanger for the intercooler and the end is an oil cooler. With decent flow, this size keeps temps under control at 10lbs boost. [ATTACH=CONFIG]562506[/ATTACH][ATTACH=CONFIG]562507[/ATTACH]
