5.9 Magnum Torque motor build?

So the reason I had thought that was because of the turbo diesels, the turbo Cummins makes tons of power real low, @3,000. That might just be a diesel thing, IDK.

Long stroke, long rod, cams totally different.... allowing the combustion process to complete, and for helping spool up the turbo at lower RPM's (it is still a rather slow spool up time) and totally sacrificing upper RPM breathing... which does not exist anyway in the tiny intake manifolds for those engines. The size is to get the boost levels waaay up, which the diesel can stand due to the combustion process being so different (as mentioned). Apples and oranges....

To make a turbo work well at low RPM's for a gas engine like these, you typically put in a smallish cam with wide LSA and small overlap, push the CR up a bit, put on a SMALL turbo, and tweak the impeller blades. Those things are what help the turbo spool up better at lower RPM's.
