RoXanneBlack8

yeaaaaaah.

comp test on another rx8....not mine....(a few hundred miles on the engine....2007 MY)

R1
8.8
8.6
8.8


R2
8.7
8.6
8.0


why is one side of the rotor of R2 so much lower? if it was an apex, two sides of the rotor would be low....how can only one be low?


side seal damaged?

Your overall numbers are good. The low chamber would need to be off by 1.5 before it would be considered a failure.
The low chamber is a sticking or worn side seal.
