Okay, I have been looking into a turbo diesel truck for several months now and while test driving a Powerstroke Ford with the 6.0, I noticed something interesting. At freeway speeds, it seems to be at about 8-10 psi all the time. Is this a bad thing for the overall life of the turbo? The turbo is spinning anyway when the motor is running, so I guess I really don't think having it make boost while it spins is bad, but I am definitely not the diesel expert! When I asked the dealer about it, he said that Ford went from the bigger 7.3 with a smaller turbo to the 6.0 with a bigger turbo to help with power delivery.
Anybody out there with one? Thoughts on Duramax/Cummins?
