Ideally you will want injectors and ultimately a cam with rods/pistons if going north of 700whp. I have been down this path already starting with the high side pump only, then adding injectors. The high side pump upgrade will get you to around 600whp on E80 or 650whp E60 in positive DA. Add the +30's will get you close to 700whp on E60 with stock cam. They would support more if the LPE HPFP could keep up. So maybe this pump will go a little further. Add a Cam with a 38% lobe now you should be able to get to 800-850whp on E60+ along with the pump and injectors. Want more, then you need the +65's.

if it will drive a 44% lobe without issues at higher RPM, it could potentially have a bit more capability. The biggest problem I see is the inlet and outlet side of these hpfp are not large enough to flow the volume needed to run full E at big horsepower levels. 3/8 is only going to flow so much. Also the 250bar capability does not matter when all of the current injector offerings will not run that pressure(3600psi). There will need to be some bigger injectors that can handle 3600psi to maximize these pumps capabilities, because if you have to turn the rail pressure down to keep the injectors from misfiring, I don't see it gaining anything over the LPE.
