what are good compression numbers in psi? i think that is the right term.

congrats n4ji. let us know what she feels like.

 

YEAH BABY!!!

 

A great rotary should have about 100psi on each rotor, anything less then 80 is in need of a rebuild.

 

nah still doesnt run.. its a mystery

took it to a mazda dealer because i was stumped.. theyve had it for 2 weeks and cant find anything wrong yet

 

where can i get a compression tester? and how much do they run for?

 

Compression testers are relatively expensive I believe. Just take it to a car dealer (preferably Mazda) and they can run a test for around $70.

 

nah dude compression testers are like 20 bucks around hurr =/

 

Blasphemy! I was talking to a guy at Tom Wood Mazda (right down the street) and he said they cost $74! I hope you get your TII running again, it was a fun car to drive when I went and saw it over the summer.

 

lol well the tester i got was that cheap, it sucks but it works.


yeah it was fun to drive for the one day i was able to drive it!

thanks though.. im gonna call the dealer and figure out wtf is going on

 

you must be thinking of standard pressure gauge testers. The mazda tester is a proprietary tester for rotary engines and definatly cost more than $20

 

Hmm, you would think that maybe Mazda would write down compression test procedures and standards somewhere, like in a service manual or something like that. Oh well, since nothing like that exists, I will guess that those numbers were probably the deflections of your fan belts in mm, which means that they are a bit tight, but the AC compressor belt is fine if it was the one with the 7.9 reading.

About $1,600 new.

 

yeah.. the mazda tester...

wow 1600 half the price of my car!
