Compression results
Hi, I had a compression check done on an fd I might be purchasing soon and these were the results:
rotor 1: 8.0 8.2 8.0 rotor 2: 8.9 8.8 8.7 Now, I searched and read through quite a few threads and these seem to be pretty good numbers, but my question is how consitstant should they be? Is a .6 or .9 difference in the rotors that bad? Thanks in advance for your help. :cool: -Matt McKeever |
Well on each rotor, the compression is close on on 3 faces but with teh 2 rotors so different its kinda concerning.. Youd have to ask one of other members for their opinion but id say that isnt too good with them so different..

These are the specs on Cirian's webpage:
My '93 shop manual says 690 kPa {7.0 kgf/cm2, 100 psi} minimum @ 250 RPM. Differential limit of chambers is 150 kPa {1.5 kgf/cm2, 21 psi} @ 250 RPM. You are within 1.5 b/w each chamber so according to these specs you are fine. |
OK, thanks for the quick replies guys.
I also read somewhere that the chambers should be within .5 kgf/cm^3 of each other, but according to those numbers it should be fine. Maybe I can talk him down on the price some.... |
Those numbers are fine. Good motor.
