Whilst the P7100 conversion is not at all an inexpensive proposition (the Scheid package starts at slightly below $two,300, less than the pump), the parents serious about undertaking the swap have possibly entirely experienced it Together with the VP44/electronic method or are generally right after making a lot more horsepower with their truck.
As for your aforementioned star wheel adjustment, turning it towards the passenger aspect from the truck opens the gas rack more. The gas rack controls the amount of fuel that’s permitted to enter the pump’s plungers and barrels.

A reworked throttle linkage is warranted in a very P-pump swap as well. This version incorporates the throttle place linkage ball through the 24-valve software into a linkage assembly originally created for the twelve-valve engine. It as well is included in the Scheid Diesel P7100 conversion kit.

Probably the most pressing overall performance hinderances Using the VP44 pertain to lower gas quantity and a scarcity of available substantial-rpm fueling. For sure, raises in horsepower could be manufactured, but it really’s nowhere in close proximity to the extent of likely that exists with the P-pump. Through the manufacturing unit, the VP44 can only gas to 3,two hundred rpm and most aftermarket tuners—even though they enhance horsepower—don’t supply for fueling past three,200 rpm.
As mentioned, a 12-valve equipment housing must be bolted to your 24-valve Cummins’ block so that you can furnish the P7100, however , you’ll also need the correct pump push equipment, the appropriate throttle linkage, a cam sensor adapter, P-pump assistance bracket, P-pump oil feed line and a whole host of other miscellaneous elements.
By now you are aware that the VP44 injection pump is limited in its higher-rpm fueling qualities — that it’s still left you stranded before (and likely will once more) — and also you’re all set to toss inside the towel. But what if there was a way to boost injection program reliability and add appreciable horsepower simultaneously?
We’ll Take note that Bosie arranged both the rocker arms and press tubes the same way they sat while in the motor (so all wear points global warming meme coin would keep on being a similar when all the things went back collectively).
The lifter holders were being then eradicated and also the manufacturing unit drive tubes reinstalled, together with the valve bridges and rocker arms. Following that, the inventory entrance go over (which can be reused) was cleaned up and fitted that has a new crank seal, the provided P-pump bracket was bolted into the block, and Scheid’s camshaft sensor adapter was mounted in the new gear housing (proven). The manufacturing unit camshaft sensor must be retained with the truck’s tachometer to operate.
The holders grip the lifters and suspend them previously mentioned the cam, letting the cam lobes to obvious them in the event the cam is eliminated. Before the cam was pulled, the lifter holders had been zip-tied in place, then zip-tied jointly in pairs.
As being the camshaft was staying pulled, Bosie was exceptionally thorough not to break any from the bearings. For the reason that aquiring a lifter fall following the camshaft is removed usually means you’re pulling the oil pan, Bosie inserted a 1.five-inch diameter pipe within the cam’s bore when the cam was out, for included insurance plan. For equally Avenue and Competitors purposes, P-pumping a 24-valve has prolonged been regarded as giving the top of each worlds.
Opposite to what some might have you believe, the P7100’s robustness, general performance and trustworthiness Really don't ensure it is easy.
It represents uncomplicated horsepower for the people useful having a wrench, substantial horsepower for anybody prepared to commit some cash and — such as Cummins engine it absolutely was bolted to — million-mile toughness.
