fuel pressure rates

[Anthony Huczek]

how much does fuel pressure vary in a naturally aspirated application?

I have a 2.5L daytona that has been converted to mpi with full turbo electronics. what im wondering is what if any changes there will be in fuel pressure as rpm's increase. I know that they increase according to boost(in laymans terms) for turbo applications but as I understand it this isnt true for n/a's.

im running about 45-50psi at idle and I do have an adjustable regulator.

sounds like too much fuel for an n/a engine. N/A's usually are 35 or so.

right but my car isnt tbi injection anymore. its mpi with turbo electronics and the motor isnt stock.

i was just curious what the factory turbo pressure is at idle and what if any increase in pressure I would see with an n/a setup.
