I only run one, as in a single CP3 on our shop truck (Dodge). The twin turbos will not provide enough air for the fuel the pump makes. It is easy to be unbalanced everywhere else, when fuel is not the issue. With the tuning you guys have available (EFI Live), I would think 850 RWHP, with enough air and a single CP3 would be do-able.
Also these injectors do not like to see over 26,000 PSI for extended periods of time, these pumps can keep the pressure up to the point of injector failure. I know for a fact, as I have replaced mine once, I also think Pat blew one in the salt.
2 of these pumps together, would be like 3 1/2 stock CP3's. For most bigger seems better, beyond that control becomes an issue. It is good to have an abundance of extra pressure through volume, but you don't want so much that you can't keep it to drivable levels concerning cruise pressures.
Can anyone pull down the pressure from dual CP3's? I am talking about a kit with pumps that are pretty new, including the one in the valley.
