Hans said that the fuel pressure is 5.8 bar now. He also said that the stage 1+ is close to 6psi of supercharged pressure..GuidoK wrote:Are different injectors not an option?bmwZ wrote:
No, the engine has original Internals. The boost is only 5psi, so it should be safe. It has original injectors, so this is the limit for the kit. They are maxed now. That is why they have upgraded the fuel pressure, so they could boost 1psi more for the stage 1+. It's not a twin screw
Afaik the n52 already runs at a high fuel pressure. 5 bar or something like that? More than the m54 (3,5 bar).
Maybe they want to keep cost a bit down.
70whp is an healty upgrade though.
Still 30Nm of extra torque too, so in the lower revs it should still be noticeable.
Since the engine can't handle that more pressure, I think it was a good decision to go with stock injectors. It made the kit more affordable and easier to install.
