Message: [QUOTE="elrodalexander73, post: 1142733, member: 16217"] I'm curious to see what HRT brings to the table, I'm on the hunt for a good E9 mack pump to make what I want work, I will be impressed though if he makes big power though. This system is such a hard system to build real big power with, and having the pressure drop over an injection event is what plagues it like you said, mind if I ask how many people have dropped alot of coin on a set of real parts, kinda like CDS did when they released billet pumps years ago and they were real expensive... Still are too. I just wonder how many injector builders have machined custom armetures, intensifier pistons, stuff like HRT is doing ya know. I know a good 14mm P7100 from CDS is super bucks, something closer to 8k and they offer pumps larger than that if I recall, and thats just the pump, not the lines, not the injectors, or anything else. Hell Jeremy Walkers big bad 3406b 4" single runs a CDS billet pump, had a chance to see it in person, makes big power numbers and pulls with the supers all day long. The kinda coin and development that has went into the P'pumps with custom plungers, quickrate cams, lazer cut delivery valves, ect all came to the cummins engines through years of big time tractor pullers all the way back to the 80s spending bookoo bucks on big dollar stuff, were talking 30+ years of development here, and millions of dollars. I don't think the HEUI injector will see that kind of investment but thought is what if some truly brilliant people and a large sum of r&d money were thrown at them with a top notch machine facility. I mean this what the NTPA tractor pullers are doing with large amounts of Sponsor money to win.. As you can see common rail is not found on any big time tractor yet, just the billet inline pump design. Just my two cents on what may or may not be left for the future. [/QUOTE]
