Is the CP3 a good pump?
The CP3 injection pump’s sole job is to create and regulate high-pressure fuel (it’s not timed with the engine’s crankshaft and camshaft). The fact that the CP3 came from Bosch’s heavy-duty line of injection pumps also speaks to its great reliability, as it was designed to play a vital role in million-mile engines.
How much horsepower can a CP3 handle?
In both Cummins and Duramax applications, the factory Bosch CP3 pumps can only flow enough fuel to support about 600 hp at the wheels. Adding more fuel via larger injectors or a bigger pulse width tune at more than 600 hp will result in a drop in rail pressure, which leads to less horsepower.
How do you test a CP3 pump?
You can simiulate max output for the CP3 by unplugging the FPR and fuel sensor. This forces the CP3 to put max output on the fuel rail. To do the check you will have to pull you glow plugs and watch excessive fuel from coming out the glow plug holes.
How much HP does a 10mm CP3 add?
800HP
Description. Exergy Performance Duramax 10mm CP3 Injection Pump will support up to 800HP on 2001-2016 Duramax applications.
How long does it take to do a CP3 conversion?
about 16 hours
2 to CP3 typically requires about 16 hours, with most of that time spent removing parts to get to the pump that sits at the front engine valley.
How do you test a CP3 injection pump?
How can I tell if I have CP3 or cp4?
Basically whe a cp3 quits working it just quits without exploding. It’s typically a slow decline. The cp4 on the other hand doesn’t have a pinned piston and if it rotates slightly it tends to explode and send tiny bits of metal all through your fuel system.
How much HP does a 10mm cp3 add?
How much HP can a 10mm cp3 handle?
Registered. A stroker cp3 is a high performance cp3. The 10mm pump can push iirc 30% 35% more fuel than a stock one. They’ll fuel up to 750 800 hp with the right injectors.
Can you put a CP3 pump on a 6.7 Powerstroke?
H&S Motorsports CP3 pump is mounted where a dual alternator would be located. This kit must be used with a 6.7L Cummins CP3 Pump. HSM recommends running an upgraded low pressure fuel system when running this item.
How does a CP3 pump work on a rail injector?
This is a one-stop symptom checker for issues related to common rail injectors and CP3 pumps. High pressure is built and then delivered by the pump to the fuel rail manifold. Afterwards it then flows through the injector lines and connector tubes to get to the injectors.
How much fuel pressure should a CP3 pump have?
Where there is a low fuel supply or none at all there should be 10 to 15 PSI to the high-pressure injection pump or the CP3 at idle. You will need to monitor the rail pressure to be sure that during cranking you have over 4000 PSI. If it is not, a hard start could be caused by one, or even more, injectors.
What causes a CP3 pump to stop working?
High-Pressure Injection Pump (CP3 Pump) Most starting problems due to low pressure are caused by bad injectors as a result of erosion of the check ball seat. The pressure is supposed to default to a max of 26,107 PSI when you unplug the fuel control actuator. The pump cannot build an adequate amount of pressure if the injection system has a leak.
What is a Bosch CP3 pump?
Many are built from brand new Bosch pumps, and are capable of extreme horsepower and should only be used with high flow custom injectors. This performance CP3 pumps can double the fuel of your stock CP3.
