Hello, I'm sure this has been covered before, but I could not seem to find it. I'm currently planning on getting stage 2 pure turbos installed. Car is 08 335i FBO, with stage 2 lpfp. I was wondering how much whp I can run on an E50 mix without putting too much stress on the HPFP. I understand every car is different, but does anyone know the general rule of thumb for this? Also I am in cali, so gas is terrible

Healthy car, decent parts, I usually see between 470-530, most just over 500ish before fuel pressure starts to dive. Depends on a lot of things.

This is all hypothetical, but is 600whp doable with it? Would only run the tune once every month or so.

I haven't seen it. It's generally speaking a bad idea to plan on maxing hardware, and a much worse idea to plan on maxing fueling. Proceed cautiously.

A fbo inlet outlet e60 stock turbo car maxed out will outflow or max out the stock hpfp. Based on mymy experience at 22-24psi on a low mileage car with newer injectors and hpfp.
