1. Atmospheric pressure is roughly 14.7 PSI. So if you divide your 205 by 14.7, you get a 13.9:1 compression...... As someone else said 'Is this a diesel'? This method is a little bit inaccurate as you loose a slight amount of your air pressure through your piston rings. Also this all changes when you add a Turbo. You have to work of inlet pressure, which of course changes with a Turbo.


Using that system my car has a compression ratio of 11.22 to 1 I think not.

165psi / 14.7 =11.22
