Who makes the biggest High Pressure Pump for the Duramax right now? By biggest I mean the most flow at max pressure.

I probably am going to be looking for more fuel next year but I don't want to do the dual CP3 thing.

I think the cp3-4 is the big one. I've been trying to get a part # but no one want's to share or just doesn't know? I'm not sure if the stroker pumps out perform it or not.

if you want one big cp3 i think i have an idea for one to be mounted out of the valley because it needs to have an oil line run to it and a drain tube. but this one flows 240% over stock.

I was gonna say the same thing as cody, I know someone working on this right now. I think we are gonna see this by next year. Having the pump out of the valley will simplify alot of things.

you need more fuel

I have the 3.4 part numbers, they would have to be imported from Europe as they are not available in US.

We make a stroker CP3, you can contact Mcrat for pricing. It will not flow what the 3.4 will, it is over 3/4 total flow of dual CP3's though. Mcrat just set a world record using these pumps.

Industrial Injection has a 92% over flowed pump for the dodge, But dont know if they do a Duramax pump or not. You could check with them.

I tested the II pump vs the Wicked Diesel pump, and the WD pump flows alot more, especially at higher RPM's.

I have 2 Industrial Injection pumps for sale right now that have very low hours on them. I upgraded to the WD pumps.

thats what need to be done because some places are staying with one pump rule so put a big one out of the valley would be best. Grand Pooh-Bah pump

How much more does the WD pump flow? What kind of test did you run?

Where would you mount this monster if you wanted to go with a big single? Not much room if you want to do a set of twin turbo's as well.

If Im not mistaken the "grand poo-bah" is also a CP3.4??? If i remember right, I think i remember hearing the 3.4 is just big enough to not fit where the stocker is....so that IMO oughta be fine in the typical dual fueler spot by the A/C compressor??? Need to run oil feed and return off of it anyhow. I didn't know they werent avalible here:eek: explains my difficulty trying to find out about the CP3.4, i thought they were installed on the Duramax I-6 cylinder engines on the big Isuzu cab-over trucks? Anyone have a price on these for curiosity sake:D

I'm guessing our current cp3 electronics would run the cp3.4? I'm also thinking a commercial truck scrap yard would be a good place to look for one of these pumps?

I THINK I remember reading somewhere that the FCA is quite similar between the CP3.3 and CP3.4. SO we would probably be able to control it the same way via the ECM.

I could be all wrong tho
