I didn't just say they were equal, I said for 600hp a C15 was BETTER. The ONLY reason Caterpillar choose the C18 over the C15 in the 865/875 is because it made in easier to pass emissions and it cost exactly the same $$ to build. At the same fuel settings as the 865/875, you will not be able to tell the difference, just a little higher boost PSI and higher NOx.
