Ford EcoBoost engine teardown

Exactly as promised, Ford sent a couple of technicians to the show floor at the 2011 Detroit Auto Show in front of a live audience to disassemble the 3.5-liter EcoBoost V6 engine that was torture-tested for the equivalent of a few hundred thousand miles of rigorous duty on the dyno and in the engine bay of various F-Series trucks.

How'd it fair? Rather well, we'd say, and it managed to churn out 364 horsepower and 420 pound-feet of torque on the dyno after all the abuse it took. That matches up rather well with the factory ratings of 365 horses and 420 lb-ft.

As you might expect, there was a good amount of carbon build-up on the piston crowns and the valves – think of how much dust was surely ingested over the course of 1,062 miles of the Baja 1000 race, which this engine took part in, finishing first overall in its class – along with a 13-percent loss on one cylinder during the leak-down test. All other initial measurements were well within factory tolerances, and Ford will continue testing each individual piece from this engine to ensure its durability.

No doubt about it, this is an impressive showing for the EcoBoost engine. See plenty more pictures and a first-hand recounting of the tear-down process at PickupTrucks.com.
