Compression test results for my car
My brother has a mazda rotary digital compression checker and we used it today on my fb. Here are the results:
Front: 5.4/5.2/5.2, 217 cranking rpm
Rear: 5.0/4.8/5.0, 201 cranking rpm
The minimum spec for a stock port 12a is 6 bar at 250 cranking rpms. Extrapolating for the lower cranking rpm, I am probably right around there. Also, my half bridge definitely makes the numbers lower. All in all I am pretty happy with the results, the pulses are pretty even and the car pulls good.
Btw, for anyone in the NJ area who needs a compression test PM me. My bro commented that it is much easier to get to the spark plugs on an FB than an FD, so I am sure he'd be willing to do it for cheap for us guys
