Over on Facebook I announced that the stage one injectors are getting an upgrade-
"First look at the new stage one injectors, featuring brand new German manufactured bodies, nozzles and pintles based on the G code nozzles our original stage one injectors used. These new injectors feature a larger charging port cavity to fit a much larger spring with extra coils to extend the lifetime of the injector before it starts to drop pop pressure, while still retaining the oem Stanadyne shim size. The nozzle tip is beveled for easier installation into the cylinder head, and the end cap is anodized to prevent any rusting from water seeping down the injector threads, a common issue with the oem design. The cost of these injectors are slightly higher at $500 shipped, but require no core, and will maintain a more consistent spray pattern, pop pressure and performance than any rebuilt injector that reuses original components.

Using the same German manufacturer, Ive been working on putting together a design for a new head and rotor for our pumps, basing them off the existing assemblies but reproducing them with some upgrades to handle the heavy loads of a high displacement pump with our modern dry diesel fuel. Next week I will get to test the first of these head and rotors in a ford db2 housing, the upgrades it has over stock are:
-.370" plungers over the stock .310"
-1/2" cam ring pin
-Single discharge rotor assembly vs the dual outlet on the factory assembly
-.050" extra stroke from the custom cam ring
-3/16" over bored delivery valve passage
With this using all new components, it solves a lot of problems with core quality and with the continued quality drop with stanadyne as their parts are being all built in china now, so the pumps are going to be a lot easier to setup and calibrate consistently, and I will be able to get much more fuel out of a fresh pump than trying to modify one half way through its lifespan, which makes for a longer lasting product for the customer as well. Working with the manufacturer I will have the ability to have these head and rotors built with .310 to .450" plungers, so once everything is dialed in and I work up to the larger plunger sizes, in theory should be able to make much more fuel than has
