Yeah. There are a few p-pumped 5.9 cr's, well used to be cr. I think people have this p-pump or nothing idea, but these common rails can make a ton of power. dual c3p's that are stock are 1,000hp + capable but with some modded units then it's really about getting the airflow. The CR injection system can do multiple injection events and allow for more precise fuel delivery.

There are a few guys out there with 6.7 cummins using the 5.9 electronics. Which allows for full use of the bigger stroke of the 6.7 without all the emissions components and electrical set-up. I know p-pump may seem awesome but the Common Rail set-up is still a great fuel system.

This isn't a P Pump but it's still pure mechanical and it's a 12v 6.7.

although the P pump is quite the fueler... it has nothing on a CR and about 100 more parts to go bad
