400 is the upper limit from my experience.

I've experienced 450hp, and heard of a fair bit more than that on the stock pump.

You measure fuel pump power at the crank.

thought about it after I posted it and it was a dumb question since different cars have different drivetrain losses.

Crank. Mine wouldnt support past 400, but it was getting weak. 450 is probably possible with a good stock pump and good electrical system, but is pushing the limits for sure.
