Baseline Compression Check
 

I was wondering if a baseline compression check for a new RX8 is worthwhile. I'm not a hypochondriac, but I did get a baseline ECG a few years ago for myself :).

Acceptable Levels..

830kPa/ 8.5kgf/cm2/ 120.PSI- Standard Level
680kPa/ 6.9kgf/cm2/ 98.6PSI- Minimum
150kPa/ 1.5kgf/cm2/ 21.8PSI- Difference Between Chambers
100kPa/ 1kgf/cm2/ .. 14.5PSI -Difference Between Rotors

Factory Settings @250 RPM

I have a feeling there is no real reason to have this done, it was probably done right after assembly anyway as QC. If they did, I wish they would have put it in the docs.

True !

Compression tests can't be completed just after building a fresh motor... Well i guess you CAN but it's pointless really.

You have to give time for everything to break into each other..

How long would you say this period is?

I wish I'd bought a compression tester (or had my home-built one calibrated/validated) when I had my engine rebuilt so I could track its progress.
