Is our hpfp used in any other di?

Isn't that what they do on the speed 3? I thought they increased thier displacement along with the pressure increase. How many cc is our pump? Is it rotary or piston?
 
There are no significant upgrades for the fuel system in the speed, they use 5th and 6th port. Essentially the same thing we do with the aux E system or Meth. Any upgrades for the speed pumps or after market pumps are for mostly for reliability, some extra flow but nothing significant.

 
So what about dual pumps then? Mount one on a bracket on the front of the engine possibly? Like dual cp3s on a diesel. Sorry but common rail big trucks are my lively hood, and it just seems like our di has some overlap with them.
 
You know that's not a horrible idea. I was thinking belt driving a small single or dual lobbed cam off of belt. Almost set it up in a v configuration and run 2 pumps off the same lobe or 3 or 4 Oh that could get interesting. Oil feed oil return. Get a factory cam and cut that beast up. Mount in pillow blocks and enclose in sheet metal.  Just thinking out loud. Haha where the cam would be so short just the lobe and 2 journals with a snout and you mounted 4 pumps radially I bet u that cam could take a beating from increased life pressue
 
I always wondered how well a cp3, cp4 or other diesel injection pump would survive with gasoline. Obviously there is a huge difference in pressure. 3000psi versus almost 30000psi. But there has to be a way
 
That's what I'm wondering. I have emailed a couple guys about possibly doing something with our pumps. It's just hard to believe I can send a 20 year old craptastic injection pump off a random motor and they can tweak that up but no one can do a thing with these?

The pump doesn't even run at 3K, it's capped at 2150 so there is some room if someone were to figure out the tuning.
 
I noticed the cap now that I'm watching fuel rail pressure through forscan. Idles at around 238 and max has been 2000 so far

Sounds like pump pressure, not rail pressure.

I see 2150 on the pump and 2300-2700 on the rail.
 
I will have to double check the pids then. I am monitoring frp-fuel rail pressure under forscan pcm module? I see no checkbox for pump pressure? Would you happen to have the formula for the rail and the pump?
 
Fomo what are you talking about pump pressure?

When i log fuel rear pressure and fuel rail pressure i think they are the same in live link..one is an oem pid and one is a different pid...can't remember what its called...but they mirror eachother in the log

I can command 3k and im sure it would deliver that in the too end but i never wanted to try that much....and i still have tested my last settings at higher boost yet...maybe this weekend
 
Since we are throwing ideas around one that popped in my head was mirroring the valve cover and pump cam shaft for the other head essentially giving each bank of 3 cylinders its own pump. Probably easier just to get a new Raptor intake manifold with port injection. Also, has anyone looked into changing injectors? VW community has been doing for a while. Get an injector from another engine, usually larger displacement, or even a different brand in some cases with a higher flow rate. Bosch apparently makes a majority of the injectors but with different flow rates and spray patterns per the manufacturers request.
 
They make larger injectors already and have value files in the SCT database....However they are useless with out fuel pressure...It's not a simple problem...I don't even think the ECU has the controls built in it to accommodate addition fueling...You would have to be able to run the drivers....Most likely the extra fuel metering would have to be done by a standalone unit, such as the water meth controllers.

And if you mirrored the valve cover to add another di pump, I'm not even sure if both cams are the same..Something tells me the left and right banks have different cams
