Need some help collecting data.

I am looking for the flowrates and pressures for the HRVP and for the Monster VP. I want to do a comparison between available flow from 2 stock vp's versus a single HRVP and a Monster.

Dual VP44 mounting plates, cogs, chain and lines to be available to all as soon as I can get'er did.
 
Any insight for mating the lines from 2 VP's is also very welcome. My current solution is to use some stainless fuel line and TIG weld what is needed.
 
they only way i can think of doing it is if you put the fuel to a rail. i dont know how else it would work??
 
Rail wont work for a VP, the VP has indiviual line for each injector. The injectors on a VP truck ar not controlled electronically to open, the are open all the time. Fuel is pushed through the injector as the VP pushes fuel out of each of its 6 discharge ports.
 
P pumping my truck would put me out of the 2.6 pulling class and into the Mod class, not happening.

Have you figured out how you're going to do the electronics?
 
I and going to tap the harness, my industrial controls tech is telling me that he could whip up a small board that would pick the signal up and delivery it to the second pump with out any signal degredation.
 
I'd think that you could tie the pumps electronics together so that the electronic driver on one pump operates both control elements; I would doubt that the drivers would have that much current ability overdesigned though. So I'd try to amplify the driver off one pump. You would want one pump to go a little bit after another one so the pumping elements aren't fighting each other, and so that you have more duration; that delay can be adjustable and built into the amplifier on the pump driver.

I've never seen two injector lines tied together. Can you tig well enough to hold 20,000+ PSI? Worse comes to worse you can just use a hydraulic flare T or something... Damn the critical line volumes and bulk moduli. You'd probably be better off boring additional injectors into the head, I don't think there's physical space though.

$100 bucks says that $10,000 in venture capital wouldn't get to page one of this project.

Y-block for each nozzle.

the trick would be getting boths pumps flow rates and time that same.

also timeing the gears together and spin the pumps the same direction..

def would be and all out truck with limited DD capabilites due to the stuff that need to be done tot he front
 
i would say run 2 lines to each injector and then have some kind of a fitting to hook the 2 lines to the one injector. i do really like what begle1 was saying about just putting a whole nother set of injectors in there. if ya want to get crazy just machine a head from scrach and put a spot for the other injector. :rockwoot:
 
There is a video of a dual pump 6.2 floating around. It is a tractor over seas somewhere running a hx50 single. He had individual lines going to a T that fed a single line for each injector.

Two times the VP44's = two times the problems.
