While the CP3 pump has much greater volume, it cannot pump the fuel at as high of pressures as the CP4. This means that Cummins cannot increase horsepower and meet emissions at the same time. The CP3 can easily get you up to 500 rwhp all day every day, but it cannot do it and meet emissions.
In order for Cummins to increase horsepower and meet emissions, they had to go with a higher pressure pump. This is one reason why I which that Ram stop this pissing match with Ford, because I would much rather the engine be reliable than tow some number than I will never tow. If I want to increase power, I can do it after I buy the truck. The CP4 is is what you get for wanting Ram to continue this pissing match instead of focusing on reliability. So blame yourself for the CP4 if you are one that believes that "Ike times matter".
industrial injection has a 10mm CP3 that comes with their conversion kit, and has EPA approval. Why wouldn’t Cummins be able to do it?
