I think he meant the first p-pumped 6.7. He did ask who will build the first "bombed 6.7", I think he was refering to a real injection pump. :hehe:

Definately won't disagree with that statement!LOL But Reb has been playing with it, if anything he would know a great place to start.

Unless you want to go out and buy one and tear it down and be happy with a 30k truck with 8 miles on it completely apart in your driveway.:umno:
 
I was just thinking of the motor, screw the rest of the truck, find a brand new wrecked Fedex truck and get the motor out of it then p-pump it and throw it in your pull truck. See its simple.........:hehe: :hehe: :hehe:

Who wants to volunteer to get in the accident with the Fedex truck so we have one to part out?
 
We could probably set up a trap.................:evil


I can see it now, mid 70's Ford F350 doing about 70 mph, broadside the Fedex truck, then about 5 dudes pile out of a dodge that shows up with tools, ripping the engine out of it right there. :hehe: :hehe: :hehe:

Just wait till there is one parked down in the SW states (CA, NM, AZ, etc) and give the guys hanging out behind the gas station (usually illegals) 50 bucks each to aquire it for you. If they succeed you get a motor, if they get caught they go back to Mexico for a few weeks till they sneek back across and you can have them try again....its a win/win situation....
 
You know it says in the new issue of "Diesel World" that Darren Morrison's new drag race truck is at 380ci. Thats quite an overbore.

Hey, if your going to do it, do it right! Get like a Krispy Creams truck so you can have a snack afterwards!!!LOL LOL LOL LOL

We also see how building a pulling truck is made simple by Tom. "Just wreck a Fedex truck!" Give idiots like me more stupid ideas to try!:thankyou2: :hehe:

so infinite tuneability was a stretch but could you imagine how fast the CR's would take over EVERYTHING if there was such a programmer? Its only a matter of time...:kick: :evil

Yes injectors from atleast F1 are around that make huge power gains but you dont have to run super huge injectors on CR's because they are part electrical...all you have to do is stretch the pulse width!

EFIlive+Massive turbo set-up+Big injectors+Big programmers=the end of the mechanical age of diesl motorsports! IMHO:rockwoot:

If you sit down and do some math, I think you'll still find that currently, a bombed mechanical system can deliver MUCH more than existing CR pumps & injectors. It's not nearly as simple as "just extending the pulse width."

A year from now I could be wrong however....we'll see.

Valid statements. However, there's even more to the equation when efficiency and fuel pressures are taken into consideration. Per injected mm3, the CR system's injection pressure allows for a more complete combustion than a mechanical pump.

Agreed...however the lesser combustion efficiency doesn't seem to be hurting the high-end pull/drag trucks. So it's not obvious to me yet why the better efficiency isn't showing its potential yet.

Maybe until (any of the) CR (engines) run fully fueled to 6000 rpm, we won't know.

Who would have thought that computers would be a serious limitation?
 
If you were to bore a 5.9 to 20 over were does that leave you in cubes ? approx 368 ?

I was more pointing out the fact that if you have 100hp injectors on a P or VP they are not a "controllable" as a set of CR's due to the introduction of the soleniod injector, so you can run maybe 200hp injectors and make them much more "controlable". IMHO$.02
 
Well, yeah, for street purposes, you take a giant stick and just "blink" it.

However we got to talking about ruling the pulling track and that's another matter altogether. Let the smoke fly!

The mm3 of fuel that a CP3 puts out in relevance to what a P-pump puts out in mm3 for the same RWHP exemplifies it's greater efficiency. CP3 ~120mm3 for 500hp, P7100- 450cc. Most of the gain is in rail pressure. Imagine a P7100 turned up to 32000psi?:hump: :hump:
 
Untill the CR has a stand alone system with unlimted control there still going to b limted but when that time comes LOOK out

I think 450cc's of fuel will make a tad more than 500hp.......
