Cool, thanks. For a while it seemed that there was a lot of chatter about CP4 failures and the risks of going to a stroked CP4 so glad to know they are good. I have dual alternators so the stroker is a better solution for me.
That was for stock pumps, not upgraded /improved pumps or 10mm pumps
Exergy does a mind bogglingly tough test on all their improved & stroker CP3 and CP4 pumps that simulate random injection pressures over a simulated life that is equivalent to a 100,000 mile drivetime life. All their test pumps on the models they sell must pass this test before being put into production.
All of their pumps have dual screen mprop valves, a built in failsafe to shut the pump down should it come apart and all their internals are cryogenically treated for a longer life and a more durable coating so no debris moving around in the fuel.
If that doesn't give you or anyone a little bit of a warm fuzzy, idk what else to tell anyone lol.
I'll take a single pump over twin pumps any day. Don't have to maintain 2 pumps, deal with plumbing for two pumps, easier to tune, straight drop in, no added wiring, and best of all you're only worried about 1 pump if something does go wrong. Also, like doo dah mentioned his truck has twin alternators (as does mine) so going twin pumps requires some relocation of parts and more work involved so for his case and mine, a 10mm would be easier by a long shot. I personally plan on an exergy 10mm Pump when I get around to doing a different turbo.
Dealing with twin K16's on my old 6.4 was a nightmare when I was having random drops in RP
FWIW...I watch Lavon Miller drive around in his 2004 Quad Cab here locally with a single 14mm Stroker CP3, the enforcer 6.7 Cummins motor, an S472 High Pressure and an S488 Low Pressure and 300% exergys and the damn truck makes 1400whp time and time and time and again on their dyno holding FULL RAIL PRESSURE. with a single f**king CP3. And him and all his guys run single stroker pumps and drive their trucks daily. They blow all sorts of parts but they almost never and I mean never lose a pump. It really proves their durability to me.
And for those people questioning a stroker CP4 on a Ford 6.7...Ask Big R (Papa D) about the one supporting his Fleece 63/Precision 76 on his 17 King Ranch lifted CCSB on big 22's and 35's making 725-750whp.....trucks runs flawlessly
