Having never owned a 6.9 until now, I've never really been around them but I've noticed on the ones that I have heard that the sound different when they run, Kinda a higher pich w/o the loud rattle. Having 7.3's around me most of my life it seems they have a lower tone and more noticable rattle.
I'm not talking about exhaust, but the sound of the engine while your standing infront of it. Last night I had 2 7.3's runnin one turbo one NA and the 6.9 turbo, the 7.3's sound identical(one 91 one 94)
Does the comp ratio make that much difference or are the 6.9's timed different? Or is the timing just retarded on every 6.9 I've ever heard run?
