Snap throttle compression should be about 80% of cranking compression. Let’s analyze the results .I got my compression test. What do these numbers mean? You should have gotten numbers in a format something like this: Rotor 1: 7.5, 7.6, 7.5 Rotor 2: 7.2, 7.3, 7.3 250 RPM. The 6 numbers, 3 for each rotor, are your compression .

Most specialists will provide you with the six results already normalised to 250 RPM. This is important because the cranking speed has a direct impact on compression test results and any changes to the standard RPM rate .
Mazda rotary compression test results should be normalized to pressures produced at 250rpm. What this means is if your results where read at 285rpm then the compression figures would be lower when normalized to the standard 250rpm. And obviously visa versa (if your had a starter cranking slower than 250rpm) What should be my results look like.For comparison, I have an R3 with 83k miles on the original engine, compression test came out 4.6,5.1,5.3 on the front and 6.3,6.3,6.3 on the rear, yet it starts and drives absolutely fine and pulls as hard as you'd expect it to.Just had a compression test done on my stock 2004 Mazda RX-8.

What compression is considered 'Good' these days?
Customer: Mazda RX8 - I have had a compression test done on the two cylinders and the pressure is about 0.8 p.s.i at 250 rpm in each. Is this anything to worry about as the car appears fine to drive or are there some symptoms that I am not aware of that I should be looking for? A compression test can show up a much more than just overall low compression. It is possible to diagnose a broken side seal or apex seal before major damage occurs. It is amazing how much damage a rotary can with stand without any rattles or other obvious symptoms so a compression test can be very useful.
