That’s true but injection wasn’t “limiting things” - It was people being intimidated by the tech. That isnt the case here. The tech is limited on this platform and therefore limits the results.
Like for like other platforms are making bigger power with DI than we are because of the limitations. Outright power im saying.
OK, @doublespaces wants real conversation. I can regurgitate stuff that has been hashed out over the last 4 years. Why don't we talk about the facts as we know them:
1. We aren't the first DI platform by a long shot. Oil burners have been DI for decades now.
2. The injectors are NOT a limiting factor. Continental did release an internal white paper concerning the N54 injectors showing their flow (among other things). These things can handle about 1300hp on full E85.
3. The injectors are only half utilized. In that same white paper Continental explained that because the injectors needed to be piezo style for the design requirements, that means that each injector has a piezo element in it. Knock sensors are piezo elements. Continental did explain to BMW that their injectors could be used for direct in cylinder knock monitoring as each cylinder has a piezo element in it when using their injectors. BMW was presumably already beyond the design stage on knock control, or there is/was another technical hurdle to using this feature, because they didn't utilize this feature.
4. These injectors can run an N54 engine without a HPFP at all. Only on the 70psi LPFP they can allow the engine to function to support the vehicle running 100kph.
5. When we run out of fuel we are "draining the rail". This is the same thing the Cummins guys have been running into for decades. They call their LPFP a "lift pump" (lifts the diesel out of the tank), and their HPFP their fuel pump. For almost 25y to overcome draining the rail they simply add more pumps. My brother ran 3 LPFP's and 2 HPFP's on his 2007 Ram 3500.
6. We now have the option of adding more pumps
7. So far the additional pumps have been good up to ~800hp
8. Even at ~800hp the rail wasn't drained
9. @jyamona has insisted we haven't reached the limit of the injection tables either, and even if we have I think he knows where the injector timing tables are to open things up more.
If we regurgitate all the facts about DI over the last 4y what can we see? We see that we just flat haven't over-run it yet (now that we have the double barrel) because nobody (besides @Tony@VargasTurboTech) is pushing 750+hp on DI alone. Everyone jumps on PI...so there is a limited pool of testers and developers for DI to really push things.
The "tech" isn't limiting. The "tech" is technically WAY more advanced than anything we as a community have the need for yet. The understanding of the tech is extremely low with a small pocket of individuals who really understand it and a large group of people who are simply louder screaming "the sky is falling".
