What psi would a normal NA FC should run at? What if it is 80psi?

 

thats alright, once you start have hot start problems and flooding then I'd worry.

 

im guessing this is off of a piston compression testor?

If your using one,just test the rotor 1,rotor 2 a few times to see if the PSI changes,Some time its a stuck seal from carbon,But how many miles do you have?

It would just be better to get the right compression test through Jeff, the correct machine test all the sides of the rotor (apex seals) at one time....

 

I went to Maztech to get it tested but he used the piston compression tester, because his Mazda rotary compression tester was broken. He also told me that the piston compression tester was not as accurate like Mazdas. I have 85,XXX some miles.
