I was wondering how much CFM of air volume a stock intercooler on my 1997 dodge cummins will flow. A performance shop told me that most aftermarket coolers flow about 1000 CFM.

 

Then the stock one will flow about 1000 cfm, although you really do need to define what circumstances that was tested at. Aftermarket intercoolers aren't designed to flow more (since the head is the bottleneck anyway), but to cool better. And they do that, marginally. Bang for buck, an aftermarket intercooler is a waste of money.

 

Flow at 20 psi? Or 50 psi? Or even at 100psi?

 

They flow enough to support 1000 hp at 45 psi boost.

 

What 5.9 makes 1000hp at 45 psi?

 

Dunno but it sounds pretty awesome! lol

can we find any vids of this truck? youtube or any such website???

 

Here's an intersting thought (a little off topic maybe): We're always trying to improve air flow any way we can.... ever see the inside of a catalytic converter? Compare size wize to your intercooler and try to imagine ramming 1000cfm of air through the honey comb in that thing! No wonder people pull them out.
