ISX Exhaust flow

[Rawze]

rough estimate .. somewhere between 3200 and 3860 free-flow (cfm). - based on old spec sheets of the past for the ISX.

Other Spec sheets place it in the range of requiring pipe sizes of 5" minimum and 6" optimum, for pipe ratings allowances of 545 - 715 cfm, according to its displacement specs.



The bigger question is why someone needs to know all of this?. Simply put, the less back-pressure in the exhaust overall, the more efficient the engine becomes, and the longer it will last. This is true for any turbocharged diesel engine and not just the ISX.

- I.E.> The red engine maker specifies that 5" piping is sufficient for an ISX-600 ... though 6-inch exhaust piping is more optimal.

Also, the exhaust piping, to be its optimal, should have the least amount of bends, and the shortest length that can be had. This provides the best efficiency. Combine this with Wrapping it (insulate it), and an even higher efficiency will be achieved.
