    The injectors are known to support much higher power level than the stock pumps in stock setups are capable of. Not sure what's new here. Don't get the need to generate useless hype if this thing have a slim chance of making into production. At least release some info and discuss your approach here if you gonna post this up on the forums... Is this still the single/double shotgun (overdriven hpfp from the crank pulley) approach that you guys have been working on for years...

    So are you just changing engine load and speed as recognized in the DME to change the fuel pressure? And is there anyway to raise the max pressure of 245 bar in the DME?

    Nice, I like seeing the DI do work! Now that you have proof of concept hopefully other ideas on implementation can follow.

    Hi Terry, Good memory. There were some consistency issues with the twin-shotgun that would cause lean conditions even with fuel trims within range and fuel pressure on target. This system exhibits none of those issues. While I'd say that this system is a different direction than the shotgun, ultimately some of the lessons learned through this testing may be able to be applied to a better implementation of the shotgun type of products. All of that is just conjecture at this point though. You know how development goes. Chris

    Yes...the diaphragm is not metal and could potential melt depending on where your wastegate is located

    Previously with the twin-shotgun system IIRC you were able to fuel up to 650whp or something like that, but had some sort of a flash limiter preventing more fuel, despite adequate fuel pressure. And there was also fuel pressure control issues so you were going to try to adapt an external controller for the fuel valve. There is a multi-page thread about that somewhere. JakeY was going to help you remove that limiter within the flash before you guys got in to a disagreement. Is this an extension of that work or another direction all together?

    Ahhhh, gotcha now we're getting somewhere. That's good stuff of your background as well. Many moons ago I started off with diesel injection and etc. Go into GDI by way of that. And been increasing knowledge and etc ever since. Regardless I'm subbed to the and look forward to platform progress no matter where it comes from.

    The actual fuel pump component P/N 13517616170 itself is unchanged. The implementation of that unmodified component has changed, thus the high pressure fuel system is absolutely upgraded. I believe you may be confusing common usage with the specifics; for example, we commonly call the drop-in low pressure fuel bucket the "pump" but really it's the "low pressure fuel pump assembly", and for a stage 2, the Walbro 450 is the actual pump component. Thus compared to stock, a stage 2 lpfp assy would be an upgrade due to having an upgraded pump. If you increased the voltage to the pump, or tweaked the fuel lines to allow greater flow your low pressure system would be improved but that's not an upgraded pump (over a regular stage 2). None of which particularly matters for the purposes of this discussion. Nice DI history -that's a long time! I myself have been dealing with high pressure pump design for just shy of 20 years, but not DI for nearly as long as you. Chris

    I'm also very interested in using my 3 column scaled 3.5 bar N20 TMAP sensor to control the ECU efficiently in the 22-24 psi range. Elsewhere on this forum I'm being told I need to also rescale my various maps that include load. Any ideas about which tables need to be rescaled and how?

    I did ask directly. Hence the quotation of your post. Jake just chimed In before you did. So like I said its an upgraded pump, correct? Not stock system like was said elsewhere. Upgraded includes anything done to modify the stock pump from its original state BTW. Doesn't need to be the entire changing of the pump. Out of my realm? Not really since I've been dealing with DI and etc since early to mid 2000s. But thanks for the clarification.

    Clarification: The "prototype hpfp system" is, as indicated, speaking from a system point of view. The actual hpfp itself from a component level is unchanged and unopened. 100% stock. The implementation and configuration details are different (obviously... look at that rail pressure). Chris

    Why don't you ask me directly? I'm calling it new hardware speaking from a system perspective. Don't get caught up in component versus system roles. The high pressure fuel pump is 100% stock, but its implementation as part of the system has changed. That nomenclature was my call. As for what he's proving... several things, which I'd expect would be obvious to you. 652 whp with direct injection only on an N54 is a significant step forward. No one has done it before. Not even close. There is the theory, then there is the actuality of doing it. We did it. Not sure what the confusion is, or why anyone would not appreciate/understand it, unless the idea of redesigning or re-implementing high pressure fuel pumps are out of your arena. Jake got it. It's not the double barrel shotgun, but what we're learning *might* be able to be applied to it -if so, that's way down the road. Good news all around. :D Chris

    Original double barrel shotgun wouldn't play nice with the DME. This setup looks like it does.

    Just saw the other thread after I posted. So it's not a stock system. So what exactly is he proving? That the hpfp needs to be upgraded to support more power without PI? I'm pretty certain this was known for a long time. Or am I bugging?
