The test was done by RR&R, the owner of the car before me took it there and dropped it off for the test, then picked it up after work. I talked to the guy who rebuilt the motor and he told me the comp was good. When i saw the slip...i didnt even know how to read the numbers. The place has a good rep so i trusted what he said. I even talked to mazda trix and they told me that they are good about being honest about that kinda thing, cause i was thinking about geting another opnion. What do you guys make of these numbers?

comon someone who is a pro, are these numbers ok?

 

its hard to see the graph!

 

i'm not a pro... yet

but it's not that hard. each peak is a rotor face and where it peaks out is the compression of that face.

looks like 90, maybe 100 on all faces, which isn't perfect, but it's still good...

 

Compression is a little low, but definitely not terrible. Looks nice and even across all 3 faces though, which is good.

 

VA in the house!

 

 

hey thanks alot guys, ya the car runs fine so i figured it was ok. Thanks

 

Not to thread hijack , but I recently purchaced a 93 R1 , with a "new" (2000 Mile ) Pettit street ported motor , new housing's , rotors and 3mm seals , and upon a compression test I virtually got all of the same readings. Is this normal? Thanks in advance!
