*ATTENTION*  This is a pre-order listing, I’m currently waiting on machining and packaging, I’m hoping to have everything ready to ship by July 27th *ATTENTION*

 Second *NOTE* Due to the cost to develop these and in wanting to set a fair price, my first production run is just 20 sets. After 10 are sold I will be placing an order to get more made, back orders are allowed so if you place an order when there’s no stock, be mindful that it could be 1-2 weeks before I can ship the next run!

The first upgrade for the VP44 that you can bolt on yourself!
Benefits include:

•Loads more bottom end fueling and more top end power. Consider it like stepping up an injector size (+50hp)

•Mild “lope” noise, changes the idle tone so you can stand out from regular 24 valves

•Enlarged outlet hole to .093 to match aftermarket injection lines

•Stainless steel construction is virtually indestructible

•No proprietary one-off parts, uses “off the shelf” VE injection pump springs and modified delivery valves, the same components that have been reliably ran in OEM applications for an accumulated billions of miles.

•Fully reversible! Place your original delivery valves holders into the supplied box and should you dislike the DV you can revert the pump back to them

•Installs easily in 1-2 hours, no specialty tools needed! Just a 17mm socket, 3/4” wrench, and 8mm/10mm/13mm sockets.

•With how they’re designed it allows for some variation in how much fuel they output. Currently they’re offered with the most aggressive form, but I plan on adding other variants as I get more inventory.

•No more “vapor lock” with large injectors (pending testing, they shouldnt in theory)

   Ive spent a great deal of time looking at the VP44 injection pumps, disassembling them to their basic parts, reading the original documentation, trying to find something… ANYTHING that can be improved upon!

I had a breakthrough when it came to the delivery valves, the original design had a small hole in the center of them, this hole allowed fuel to drain back post-injection, bleeding off injection line pressure into the return passage of the pump rotor. The fuel also has to do a nearly 180* turn around the delivery valve out of the holder, it wasn’t nearly optimal for flow. With my new design you’ll be able to utilize the entirety of the injection event from the pump.

Lifetime Warranty on the springs and delivery valves, no warranty for the holders galling in the pump body. If you follow instructions, you should have no trouble.
