potential gauge Q

Can anyone tell me what the std fuel pressure is on a WRX? And how much higher do people push it when chasing more power?

What about engine oil pressure?

What about coolant pressure?

Looking at monitoring these things but need to have the right guage for the job.

Standard idle pressure of about 35psi is not changed but you use a higher volume pump and a rising rate fuel regulator to push big power.
