Default Wanted: Bad/failed HPFP - 08-12-2016, 09:52 PM

As the title says, I'm looking for a bad, failed, or failing HPFP from an N54 (Any year, any model, any release HPFP). The unit must be complete as removed, and the exterior components including drive-shaft must not be damaged.

I am offering to pay shipping (If you insist)! Basically you're donating a useless part for the better of the N54 community. I am designing a mounting/driving system to add a second HPFP. Driven at OEM speed, this will in theory fuel over 1000wtq and nearly 1000whp on full e85 with OEM reliability and OEM fail-safe protection, at a price cheaper than PI.

What needs elaboration? I thought it made sense personally. I need a HPFP from an N54 that failed.

Sounds like a great idea.. Why not invest in a new one if it has the potential to make money..

The bad one is just for R/D, to design the system as a whole. Although I'll need a new one for it eventually, it'll get beat up, torn apart, mounted/dismounted hundreds of times, etc. Just easier and less risky to do all of the design with a bad one.

It's like the plastic "mock-up" SBC and LSX blocks they sell. But yes, eventually I will use a new one for actual pumping duties.

why do you think you will succeeded where VTT failed?

How'd they fail? I was under the impression it's still in testing. I just don't like that their design over-drives the pumps.

so you don't even know your competition?

they were never able to get their double shotgun kit to work properly, electronic issues. (meaning 2 pumps, factory location and one running of serpentine belt)

The one you are referring to that overdrives the pump works of serpentine belts and works fine albeit a very mediocre improvement for the $$$.

all of this is 2-3 year old developments..

their current prototype that the are testing looks promising, but no information on setup yet.

What harm is there in having more people develop products for our platform? Someone give this guy their old HPFP!

I don't understand the issue. More options means less price gouging from the competitors.

Good for you man. Someone send him a pump, everyone deserves a chance and many of the best have always stayed under the radar. My question to you Aaron is what type of experience do you have working with these type of items. I think thats a question better asked rather than giving him **** over asking for a used hpfp.

Everything about this statement is plausible, if plausible = not possible.

As discussed in another thread, the oem pump is driven at half engine speed. you must be planning a compound pulley setup or a secondary gear reduction to drive it. Neither of which will be fitting in the engine bay. Second, over 1000 anything... You must be developing a standalone ecu for it too.

Good luck, I'm curious to see what kind of design you have in mind. I've had a design floating around in my head for a while, but taken no action with it.

It's certainly possible. There are other GDI pumps commercially available up to ~700hp in a single configuration or you could go with multiple units. Just a matter of putting the time into the engineering. You have a mechanically driven pump with a single PWM control. Simple in operation, but the devil's in the details. Again, good luck.

The best way for products and inventors to innovate is through support... Playing devils advocate creates a lot of unnecessary back and forth slows down the progress.

PM me, I'll send you a failed HPFP.

I don't seen why it hurts to try. Not like VTT and that HPFPupgrade guy know what they are doing.

I have the original one from my MY09 at sitting my storage somewhere. I am pretty sure the pump internals are still pristine, since it was the fuel control valve that failed on mine.

PM me if you still need one.

Got one on the way, thanks guys. Big thanks to MMP too!

I have zero experience with this, I just have a long background of making things work when told they couldn't, and I've got a very engineering-driven mind.

I've got 3 ideas in my head as to how I'm going to get it down to OEM speed, and I'm working with v8bait who claims he can get the electronics taken care of.

Sit tight, this won't happen tomorrow, but I'll be working on it.

Let me know if you need any help on the tuning side. I'd be glad to provide any additional tables needed, or the logic behind how they operate


Enjoying the new tables discovered and the XDF progress made? if you'd like. Every bit is appreciated!

Exactly what tables would those be. The Magic "injection tables" you were holding onto that aren't needed in any way shape or form to get 700+WHP out of DI only. I love that you keep hanging the DI tables over everyones head like they are required. The only tables needed to do what we did are already defined, and available to everyone. You just need to know how to set them up. Which myself a non tuner figured out. I look forward to more DI options if this guy can bring them. For the people in here saying the double barrel doesn't work. It actually works perfectly, as showcased in our latest round of testing. I just don't have enough time in the day to deal with fueling upgrades currently, turbos already have me hiring more people just to do that. Good luck with those magic injection tables Jake...

Now these are the types of responses he should be receiving! Good luck with the R&D and hope you can make a working solution!

Nothing bad to say about Tony because he was initially the one to take on the project and made progress but more options on the market is never a bad thing.

Oh hey! Yes, the reason your original double barrel didn't work wasn't due to tables, it was due to **** design...running one pump at stock speed, and one pump overdriven.

Low and behold, you change your **** design to run the pumps at the same speed, so the DME can actually control them, and now the DME can at least "learn" within the VCV PID limits, and adjusted the high pressure req and scalars tables enough to get it to work. Yay.

So you have it figured out now and are the man...do I see you selling a DI only 700whp solution? Nope. ETA to market? Nope. Sigh...

Injection windows, injector duration, VCV PID, and Base (VE) fueling tables will eventually be required to get the max out of DI. I'm not holding them over everyone's head, just yours. Hell, proper tuning of them may make the double barrel unnecessary
