I've got about 7.5-7:1 compression...

What kind of life do I have left on my motor?... that reading came from the rear rotor. Should I lay off the boost or is this normal? I've got about 20k on a rebuild.
thanks,
ryker

I am not sure about the life, but be careful not to confuse compression ratio and compression. The compression ratio is fixed at 9:1 if you have FD rotors. Compression is a measure of pressure and it changes over time.
