Dynamic Fuel Pressure?

what average fuel pressures do we get at WOT with boost?
assuming that the pump & injectors are well matched
and static is set around 38-43psi (vaccum disconnected at idle).

Well it's a 1:1 ratio on the regulator, so base f/p w/o vacuum plus boost pressure = fuel pressure under full boost.

Re: Dynamic Fuel Pressure? (Quick 200k Mile Motor)

and because of variances with boost pressure, injector, adjustable regulators, line/rail sizes, fuel pump(s) used, and even temperature comparing fuel pressure is hard to do from one car to the next.
