Fuel pressure question

[Epic904]

Ok so base fuel pressure should be from 37 to 43 psi, but on 950cc injectors, wouldn't you want more for a base since they would be spraying a lot more fuel into the motor and the given time the ecu fires the injector? I just want to make sure that 43psi would be sufficent enough to run the motor

43psi will be enough to run the motor. I like to run around 43 to 48psi on the theory that it helps atomize the fuel better.

I'm running 850's at 37psi with no issues. My set up is much different then yours though.

We're running 1000cc at 37psi base pressure.
28psi max boost, no problems.
