VP44 Cummins driving impression 

Stock VP44 Cummins with silencer ring removed and wastegate pined/welded externally.
This is a rusty old plow truck with a NV4500 and 4.10 gears. Total weight with load is probably just under 15,000lbs combined weight.
Wastegate had complete rusted away on this engine and because of other issues the turbo exhaust housing replacing just the wastegate wasn’t possible. This is also a HX35 truck.
