Compression Numbers?

[mikesoob7]

Hi,

I wanted to know what everyone else is getting for their compression numbers for the DOHC engine? I've got a '97 SC2 and the numbers are 141 and 142 PSI for all four cylinders.

Saturn indicates the compression should be 172-205 PSI, this brings up the next question. I live at just over 8,000 ft. so should I adjust my compression numbers accordingly or are they the same no matter where you are? I read in one book to add 2 PSI for every 1,000 ft. of altitude.

Thanks,

Mike
