max fuel pressure?

Ok I have an adjustable fuel pressure regulator and it is set to 50 psi at idle. Now since it has a vacuum port the pressure changes with the rpm and intake vacuum. At wide open throttle how much more pressure will I see above 50 psi?

Re: max fuel pressure?

Regulators are there to only maintain a constant pressure differential.

More or less if u drive around with a fuel pressure guage on the car u will be able to observe 5-7 psi swings depending on throttle openings.

Only way to truly do it would be able to get vacuum and fuel pressure at the same time and record it.

later
