I just had my RX-8 at the dealer for a compression test. I figured the 8 years is getting close so it was worth the hour of time.

I believe the results suggest a case for a replacement. Any thoughts are appreciated as always.

Rotor 1 (275 RPM) Rotor 2 (260 RPM)

8.1 9.0
8.1 9.0
8.1 9.3

 

looks good to me man,

 

But I do believe you need 3 sets of numbers, one for each of the rotor faces.

 

It is 3 numbers per rotor. My understanding is there is only a tolerance of 1 kg/cm2 from the highest number of one rotor to the lowest on the other.

Rotor 1 - 8.1, 8.1, 8.1
Rotor 2 - 9.0, 9.0, 9.3

 

I think that's 1kg/cm2 difference between faces on a rotor.
Those are really solid numbers though. What's the mileage?
