Less power, less abrasive, taller, and much better looking. (sorry Wade).

True, but you don't have that for Ron's engine. We know HP, and he knows rpm and cc. If we knew his cc and max rpm (rpm @ 1300hp would be handy too) gpm less pump return is easy.
70 gpm is good for about 450cc @ about 3300 rpm. That includes injector return but does not include pump return. If he's making 3 hp per cc he's doing pretty well.

This is for any diesel performance engine up and over 1000 hp. You can calculate theoretic, but what I am talking about is actually fuel measurements during dyno sessions. The dyno achieves this by using fuel flow turbines that give readings to .001 lbs. of fuel.
here is what a good dyno looks like at GBE

Ron, buy a 70 gph fuel pump and see how it works out for you.
Calculating his cc vs his rpm to find gph is not theoretical. It's 3rd grade math that even a farm boy like myself can use to see how much fuel his injection pump is going to swallow.
Picking a bsfc number for his engine without having it in a dyno with fancy machines hooked to it is theoretical

nobody ever said to buy a 70 gph pump, that is just what the motor uses. as to needing to have his motor on the dyno, the range for BSFC on any diesel engine , even ones rolling coal is predicitable.
what you talking about is trying to use a rule of thumb.
one other thought is that most of the pumps marketed in the diesel world do not put out close to what they claim at running PSI

I have to send my pump to Kevin for some work. Would running it on the stand with the injectors give a good approximation for fuel usage at a certain rpm?

It would be best to figure it at max cc and max rpm that it will ever see.

We are working with them on the Ford stuff, we know it will work as we have already had the DI/Fuelab/Fass version working for several years now with good results.

Can you do something with the regulated return built in? That would be interesting.

use a prefilter pump and post filter , along with their Boost Referance Regulator

You are better off with a regulator AFTER the CP/VP/ P Pump/ injectors, what the fuel pressure is after is what the pumps(mechanical/CR/VP)/injectors(Ford HEUI) see.

I asked them last year some time (Fall 2012) if they were ever going to create a setup like they have for the common rail stuff aka prefilter etc and I was told as of then there were no plans for P7100 pumps. I called them directly. I guess this has changed?

Sometimes people forget "Hotrodding 101", I am pretty sure 1000 hp 12v and CR's didn't come from the factory like that and I know good an well 7.3HEUI's never thought they would see 500 much less a 1000 but we have them both.
The beauty of the Fuelab design is in the easy way of making a setup work for your application, just because they themselves don't offer a complete bolt on kit doesn't mean they don't have what you need.
We have made a variety of pump setups for quite a few different applications using the Fuelab pumps.
