M-Tronicly Obsessed
So if you counted the overpressure created by the turbo, would the overall compression in psi be roughly the same...?
In other words, do those non-turbo diesels have higher compression ratios to make up for the lack of a turbo? (Don't know much about diesels...)
I believe that is the idea. I had a 91 F250 with an IDI 7.3 and it was 18:1. They only made 180hp but torque was in the 400's. I always wondered what it would have been like with a turbo.
