S&S Diesel Motorsport Now Offering 19+ Ram CP3 Conversion Kit

To really head into the fourth quarter of 2020 strong, S&S Diesel Motorsport dropped their 2019 Ram CP3 Conversion Kits this month. I caught up with S&S Diesel’s Justin Norris to get the details on this kit and I think you 19+ Cummins guys will be pleased to hear what he had to say.

Cummins has a trust-worthy reputation for rock-solid durability and worry-free performance. The latest generation 6.7 L Cummins reinforces that reputation with a CGI block, stronger crankshaft, redesigned connecting rods, and 2,000 bar fuel system. The one chink in the newly-revised armor is the Bosch CP4.2 high pressure pump. In contrast to Cummins, it has a bad reputation for premature failure and destroying the entire high-pressure fuel system with fine metal debris, when does,” Norris said.

“Many years of engine and fuel system development experience at Cummins compelled our design team to create a refined solution around the bullet proof Bosch CP3 pump, that has a more befitting reputation. As the base component for our high-pressure pumps, the CP3 has proven to withstand extreme pressure, extreme RPM, and extreme environmental conditions; making it the preferred hardware for the S&S 2019+ RAM durability solution.”

At the heart of the S&S Diesel Motorsport, No Tuning Required 2019+ RAM CP3 Conversion Kit is a brand-new Bosch CP3NH base pump that is internally modified for improved durability, high speed performance, and tuning-free rail pressure control. The ultra-reliable CP3 is combined with OE-grade components for a truly refined kit that looks as if it had come out of the Cummins Mid-Range Engine Plant in Columbus, IN.

“The next generation 6.7 L Cummins features many design improvements that make it an excellent choice for competition builds, including a front cover that over-drives the pump at a 1.5:1 ratio. To take advantage of this feature, S&S is offering kits with high-speed optimized competition pumps. Higher pump speed equals higher output, yet there are RPM limits for each size pump.”

Pump Model Pump RPM Limit Engine RPM Limit
SuperSport
10mm High Speed 8,000 5,333
12mm High Speed 7,000 4,667
14mm High Speed 6,000 4,000

The install kit can be sold separately for those who already have CP3 pumps, with the understanding that it will work best with S&S high speed pumps. Other CP3 pumps may not be optimized for high speed operation and output could flatline past 3,500 pump RPM.
