cp3

[Walcott]

Is there any benefit to upgrading cp3 other than horsepower,i. e. towing,smooother running motor etc?

An upgrade CP3 can recover from rapid fueling changes faster, but if you have enough CP3 to obtain the commanded rail pressure I don't think youll see much of an increase.

In most cases the 2 shaft seals will leak long before the internals fail,Their is a weep hole for these seals,but if not taken care of fuel will leak into the oil $$$$. The other concern is feed pressure ,over come the CV valve with excessive pressure will cause accelerate wear. Its one helva pump.

nothing is gained. only kids playing with high hp short term burst's benefit from modified or dual cp3's.

On a stock or close to stock truck the only thing that might be worthwhile is a bag of parts.

I have considered it, but since i don't have a rail psi gauge anymore I am not sure I could ever see the difference. But when I had the gauge I would notice the rail psi drop when I hit hills and would take a few seconds to recover, a bag of parts would increase the recovery rate, and could lead to better mpgs, or more power at the throttle change.

Big gamble for $400, plus a gauge to see if it works.

I just bought a stock 06 f650 with cummins. I love the difference between stock cp3 and dual cp3 on my other truck so when funds are available I will be buying a modded pump. I feel its worth it. try it if your not happy ill give you my address so you can hunt me down lol
