Where did this assumed "500HP limit" come from? It's either a myth or the meth is enough to push it over the supposed limit.

The stock injectors were meant to flow enough fuel while on 5bar (low pressure if the HPFP fails), so you can imagine what happens when the pressure is increased by a factor of 20 to 40, something well over 500HP at 200bar. The only major bottleneck anyone has hypothesized is that the LPFP cannot flow enough to maintain that power level, but that has yet to be directly confirmed.
