I don't know off hand. It will vary from model to model of course.
I have heard anything of 110-125 psi being EXCELLENT numbers. Not sure what brand new should read, or what the lowest numbers you want to see before rebuild are. Try the serach functin of the forum for this info, you should find it pretty easily. I could do it for you, but then again, why would it ;) |
The manual says 85 for a min. and I've heard 120 or so as about the top.
For a rotary compression tester check out the Comp 07 Cheers :beerchug: |
Depends on the type of motor you have. 3rd gen is 9:1 compression ratio which means that you should get approximately 9 x 14.7psi = 132.3psi
for TII, they're 8.5:1 for S4 and 9:1 for S5 Min spec for a rotary is approximately 6.0:1 which means that if your motor is seeing around 88psi, you're marginal and needs a rebuild. |
