im in my engines class of nascar school and today we were talking abt compression ratios. and one of the "tuners" asked how would you figure out final with a turbo.. and they did it with a car that has 10 to 1 and with 15 lbs of boost came round 15 final.. so i was wondering what a 93 cummins ratio would be. we were going to figure ours with a 32 lb boost turbocharger and with the 19 that we guessed a cummins would be it was 60 to 1! so i just wanted to know what the acutal was.. thanks
