CR injector in a 12 valve ?

its not about fuel flow when your at 28,000 to 30,000 psi fuel pressure .
the pressure will let dramatically bring down BSFC , and make .significantly more power with each pound of fuel burned.
With a P pump, no mater the size the exact tune is optimized for a given rpm and fuel delivery band. With electronic CR injection , the timing , fuel delivery and pressure is optimized for every point on the fuel curve , and boost map.
There would be no need to flow more fuel then needed to make a given power.
 
Im starting to thing all that atomization in the CR system is its death knell.

I just wonder if the CR system is capable of sustaining the high pressures needed to fill injectors that flow the same as those on a 12V/sigma setup.

I' imagine that the flow needs would be insane.

the hole size would be dramatically small, hydraulic flow is based on two factors , orifice diameter , and pressure. , less friction loss.
Some one on here has these numbers I’m sure , but at 3 or 4 times the pressure a CR would need a hole size considerable smaller . With this high pressure , would also come the ability to make more power with less fuel
 
When you use excess fuel for cooling as in pulling it kinda negates the bsfc arguement.

Just out of fairness, I'll leave the sigma and billet pumps out of this one, cause I don't think the 14mm p-pumps have been surpassed by common rail yet...so I really doubt the 16, 18, and bigger plungers have anything to be scared of

Why? I'm sure the CP reference involves a CP3.4 so why not involve a Sigma or even Billet based custom Sigma design? There is nothing even near the output volume of these designs........
 
If we are talking about total volume, how about a 14mm quick cam, 12cyl pump.....
 
You p-pimping pinhead knuckheads are so stuck in your static timing and firehose world. It would be an interesting idea to get a CR injector in a 12-valve. bolt on a rail. drill out the relief valve hole and fit the second pump directly on that. Don't put greggy down for this idea, he's not going to get it to happen anyways. But you have to admit, it's a neat idea.

Everyone keeps saying "pump is king" what ever. Lets see your "800hp p-pump" start in -30 degree temps, with out a block heater and just grids. meh.

There are bigger and badder cp3's out there no one has yet to tackle. What would 2 3.4's flow? I know FloorIt's stage 4 is good for 360lph, 2 of them may be plenty to get near 2000hp... However, all that fuel is no good if we can't turn the "CR screws".

so until everyone and their mother has this ability, or eveyrone runs out and buys these stand alone units, you p-dump whiners can have your cake.

Hmmm. When did the first p-pump crack 1000hp on fuel? That wasn't to long ago was it? 2000?

Take a step back and think, the firehoses aren't simply for power.

Isn't that because you can't dynamically changing the timing and pressure?

The pilot and last event are suspect for melting things, naturally we can't remove them/workwiththem just yet. Give it time and a few hundred blown up motors. :)
 
I reject the premise that the CR heads can't flow enough to be competitive - although by nature it's more $$$ to build them... and they too benefit from individual-runner intakes (we built the 1st one last winter).

Still, it'd be neat to see a CP3-pumped 12V. :Cheer:

I appreciate your sense of humor...but let me point out something that has already gotten lost. The idea of the p-pump as king is for max power full blown competition engines only, there is no mention of daily driving or low temperature starting...if that's the base of the argument, then a stock truck would be king over all :doh:

I also realize by "first p-pump to crack 1000hp" you probably mean pickup engines, because the p-pump has held the bar unreasonably high for competition for entirely longer then the year 2000...

Until the technology is available for you commonrail guys to EARN the title of king of pumps, don't talk like you already have it. It's the same as the noob talking about how when he gets the money he'll have the baddest (fill in the blank) truck you've ever seen. So until it actually happens, us dinosaur p-dump guys will continue peeing in your wheaties every chance we get :rockwoot: LOL


This is all in good fun of course...not trying to make enemies
 
I agree it would be cool and neat but when you are at a lever where extra fuel controls egt, increased efficiency is not going to help

Don't jump ship too soon. The CP3 set up is in the works for a PSD 7.3 and would probably be easier on a 12v.
 
The mechanicals have proven themselves at being VERY effective at high HP, high rpm competition level performance.

Beating one of these engines in a steady state condition via electronics is going to be very difficult.
