North Liberty and South Bend, Indiana | Big Cam's should not be worked very hard under about 1700 rpms. Best to run them at 1800+ if pulling hard. They simply do not have the low end grunt the Cats do, so I'm told. Still trying to figure out a power issue on a C15.
You can Google power increase on Cummins Big Cam and probable get a bunch of info. One thing you may not find is the dual line fuel kit. It feeds fuel from front and back heads rather than just the front which can possibly starve #6 of fuel |
Turning up a cummins big cam?
