What is the real topspeed of the duramax, whit out the speedlimiter and what kind of rpm`s turns the engine on top speed?

(yes i now, it is a stupid question) :cool:

108 mph calculated at 3200 rpm and stock 245's.
128 with 265's

My 01 will only pull 3100 rpm and runs about 100 265s should give an extra 4 or 5 mph at those speeds depending on what brand.

My rig will run about 115-120 with 285 tires and a 3800 rev limit.
