This is just my ignorant outside opinion......if it was worth swapping I.E. gaining something useful, don't you think someone like Scheid or columbus diesel would sell swap kits?
If they could figure out how to do it...

Not without an enormous amount of machine work. But it begs the question, why? You'd be losing a lot of the benefits of the pump. If you're going to build a controller, might at well have it command both racks. My controller also controls the waste gates on both of my turbos.
I get it, but a large part of the the appeal of the P-Pump is that it does not rely on electronics to get the job done. I just thought that if you could still have the fuel rack controlled mechanically, you would retain some of that reliability. Then the timing rack, even though it is controlled electronically, I assume would just revert to the base timing if the electronics or the controller had an issue. It seems like it would be the best of both worlds.
PS, I just want to add, I really appreciate the time and effort you have put into this project. It really seems like a great setup.
I understand your concerns, but the H-pump is at least as reliable as the P-pump; at least in my opinion. And modern electronics are very reliable if you keep them away from heat.I get it, but a large part of the the appeal of the P-Pump is that it does not rely on electronics to get the job done.

Thank you, sir!PS, I just want to add, I really appreciate the time and effort you have put into this project. It really seems like a great setup.
I also looked at a centrifugal advance unit for the P-pump years ago. I think Cat used them for a little while. But good luck trying to find one of those; they are the proverbial unicorn! Also, they push the pump back about 250mm, making for all sorts of clearance issues. And it is my understanding that they were neither consistent nor reliable. Unlike the weights & springs in an old fashion gas engine distributor — which weigh just a few grams — the mechanical pieces would have to be quite large & very robust in order to handle the torque required to drive the P-pump.This is exactly the appeal my thought process as well, though now I have actually gone way from that recently and am now fully controlling my 47RH electronically with megasquirt.
But something I have thought about with the p7100 is implementing an aftermarket centrifugal pump gear that would adjust timing based on RPM. I know there were some dozers that used a setup like that. The main hurdle would be consistent timing advance while overcoming the torque it takes to drive the p7100 in itself.

Thank you, kind Sir!Very cool setup. I'm interested! :clap::rockwoot::bow:
I am confident that if that was the case, those trucks would have been far & away the most desirable, & would've dominated all the pulling contests.
I could do it to a 24v with just about the same amount of work. I have actually had a few inquiries. Anybody interested? PM me.I may have missed it, but I'm guessing yours is a 12v, have you thought about doing a 24v to see? Possibly doing retro fit kits to order?
What is attached to the injection line? Timing sensor?
Don't worry, no offense taken. I just want to be clear that this is an undertaking of considerable magnitude to tackle. I have several versions of this pump, & have studied the inner workings of these pumps extensively before settling on the exact model I used. So that there is no confusion about this, none of the H-pumps I've seen — & I've seen quite a few — are a direct bolt up.

Short answer. Yes, but I realized quickly it wouldn't do everything I wanted it to, & it would be more work adapting it (for technical reasons I won't detail here) than starting from scratch. So I abandoned that idea & made my own.Just out of curiosity, did you consider trying to use an engine controller or at least some of the components from an engine controller off of say a Volvo engine that used the H pump as a starting point? I thought about it in the past and figured maybe it would be a good starting point if you could crack it.
Thank you, my good man!It is impressive what you have accomplished there. I look forward to reading more about it.
It’s in a Ford.
Electronic control of the wastegate.
Yes the waste gates — both of them — are electronically controlled, but I'm not use the Ford PCM to do it. The Ford signal is meant to control a VGT.
Very cool, you certainly have more skill/patience than I will ever have. You don't have to worry about getting banned over here, we are pretty lenient on the rules.
Thank you, sir! Perhaps a bit of an introduction is in order. I am an Electro-Mechanical Engineer (actually a dual major, Masters in Mechanical Engineering, & Masters in Electrical Engineering. I've been in the high performance automotive & motorcycle industry for over 30 years. Several of my motors are record holders. I've designed a lot of things other engineers said couldn't be done. As far as I know, I'm the only guy who has figured out how to balance the counter-balancer shaft on a single cylinder engine. Or how to make an XR-750 flatrack motor last more than 2 races. I know all about performance & how to make motors go fast...& stay together! Engine management is one of my specialties. So you see, this really wasn't much of a stretch for me. I apologize if this sounds a bit hubris; I just thought a bit of my background might help the forum understand how & why I did it.Very cool, you certainly have more skill/patience than I will ever have.
