Looking forward to some positive results. :)

I don't know if you've said so, but you'll be doing a Back-To-Back comparison, correct? :?:

Me too..... I think that they will in fact increase fuel by a decent amount. I just wish someone could tell me that it wouldn't be any harder on the injectors.

Makes me think of the common rails... lines being constantly pressurized... they need electronic injectors.

Yes I will be running back to back only change is delivery valves...... I would take the hose along for giggles but the wife would kill me if I blew the motor in her ride

This dyno we use is conservative and he runs it with no correction factor too..... a 600 hp diesel on his makes 700 on other dyno's

I don't believe they do.... oldestof11, I bet will know how they work a little bit. I know nothing of a vp pump.

They have a "anti-drain back" valve but not a real "delivery" valve from what I have been able to find.

OK... so they have an anti drain back line... meaning that it keeps the line fully pressurized? Also, the vp trucks are a full mechanical injector or not?
