  • Cold start after removal of exhaust manifold for gasket replacement.Thought it a good idea to flash it up and clear any debris from the ports.

  • If only Class 66's sounded like this in daily service, it'd be far more interesting! Nice video. Great to hear the 66 engine unsilenced.

  • A 710 with no manifolds on, f****in awsome! Imagine the racket from that bastard under load........

    EMD primemovers are the bomb proof daddys, end of!

    so turbo is mechanically driven during start up?

  • whoa up close it sounds like a DD50...

  • hahahaha ALCO start with an EMD!!

  • @ Jim40135 that yinging sound is the gear drivin turbo charger it runs off the crankshaft till about 500 RPM then the clutch kicks off and lets the exhaust take over driving  the turbo

  • three zillion hp @ 37rpm...:D

  • How many GMP does this burn?

  • Nice !

  • sounds like a Star Wars pod racers round the 0:18 minute mark

  • was at 1:39 the airfilter?

  • @BNSF5608 It would run fine. The turbo clutch does not 'cut out' at a certain speed - the exhaust becomes strong enough to drive it beyond the geared speed. If there is no exhaust gas present (as in this clip), it will still run, even to run 8. It just won't make the power it should. It would more or less produce the power of a Roots-blown equivalent.

    That's often how the railroad will convert a GP40-2 into a GP38-2 - by pinning the overrun clutch.
