Does compression test #'s tell comp ratio??

funny my civic only reads 155!

My static compression is at 270 on my sohc. We used the compression calculator to find my ratio.

I see people out there spending money on the car to improve it … If you spend half that effort just working on your driving skills, making you and the car work together as a team, then you’ll go faster – period. To make the car go a second faster on the track takes a lot more energy and money than making yourself drive it one second faster.

Using a compression tester to determine compression ratio is not a good idea
