I think that is where it maxes out on n/a engines. Gregg B is running a fifth gen pump to its limit and has around 560rwhp. He hasn't mentioned a drop in pressure at high rpm and he is pretty careful about getting everything right.

I feel like it should handle it also. It's strange to me that I start seeing the pressure drop at lower RPM, where I'm certainly not making that kind of power. I checked the battery level (via the Datalog) during the run, and there wasn't a drop in voltage, so that wasn't the problem either...
