US test is obviously on PSI while the JDM is in Metric.
You'll have to convert to whatever you are used to.
=The Mazda Rx7 Tester numbers like 8.3..not sure about that though.
I bought a TR-01 Rotary Engine Compression Tester engine compression tester which measures in PSI.

I figured it out compression is very good if its between 8.0 and 9.0. But sadly only like 10% of the dealers show the compression test when selling the car.

Ya 9 is real good.
I went to a rotary meet about the first year or so after getting my car and a guy had an actual Mazda tester.He did free Comp checks for anyone wanting one.
I said "for sure!!!".
My engine was hitting 8.4's and people were in awe!..why?.because the car looked like ****..lol!
Does the term: looks like ****" translate in Amsterdam?..also means looked liked poop,crap,Garbage,junk,rickety,beaten up,..plain old jalopy!...(Sorry I have to amuse myself somehow!)

Not to get off the beaten track of the topic but it was an FC..and N/A at that.
It would be nice for dealers to have a documented Compression test of the engine but half of them done;t even know what that thing IS or does under the hood.!
(looks like a Keg of Beer there,Leroy...where do ya tap it to get the suds?)
