Ford bumping up HP/Torque numbers on new Diesel
Exhaust Notes - A Blog from MSN Autos - MSN Autos
General Motors Co. is enlisting its dealers as it fires back in a horsepower battle between diesel-powered heavy-duty pickups.
Ford will begin production this week of the most powerful diesel engine ever installed in a heavy-duty pickup, Barb Samardzich, vice president of powertrain engineering, said today in a statement released here at the CAR Management Briefing Seminars.
Dealers will make sure pickup buyers who purchased Ford's brawniest truck over the last four months get the power boost, too.
The 6.7-liter Power Stroke V-8 turbocharged diesel powering the 2011 Ford F-Series Super Duty, introduced in April, will be upgraded to 800 lbs.-ft. of torque and 400 horsepower, an increase of 65 lbs.-ft. of torque and 10 horsepower.
Ford's powerplant had fallen behind a competing engine offered on General Motors Co.'s heavy-duty pickups. The Chevrolet Silverado 3500HD and GMC Sierra 3500HD come with an optional Duramax 6.6-liter turbodiesel V-8 that puts out 397 hp and 765 lbs.-ft. of torque. Now the F-350 Super Duty can reclaim bragging rights in those categories.
Fuel economy is expected to improve at least another 2 percent, making the 2011 F-Series Super Duty 6.7-liter Power Stroke diesel a full 20 percent more fuel efficient than the 2010 version. The improved torque and horsepower mean that a driver can get to a higher gear faster and stay in it longer, both of which aid fuel economy.
Besides selling the upgraded engine in new Super Duty pickups, Ford will provide the upgrades free to all current owners of a Super Duty diesel pickup. Customers will receive letters explaining the procedure -- a 30-minute software adjustment to the pickup's powertrain control module -- and inviting them to visit their dealerships for the upgrade.
The upgrade program will begin by Aug. 31 and continue for the next 12 months. All 2011 Super Duty diesel pickups in dealer inventory also will receive the upgrade.
Marc Cross, co-owner of Jordan Ford in San Antonio, Texas, endorsed the program in a statement.
“It's human nature to say, ‘Darn, I should have waited,'” Cross said in the Ford statement. “But with this program, there's no penalty for being an early adopter, so to speak.”

The fact that modern diesels are completely computer controlled. A 10hp change means absolutely nothing to a 300+hp engine, its pure marketing.
All they would need to do is increase the fueling rate a small amount at peak power and they've got their numbers with no impact on engine longevity, performance or emissions.
This isn't an old mechanical engine where you turn up the screw and get power over the whole RPM range to increase horsepower, an ECM can change fueling in a specific 5rpm range if they want it to.
Cummins and Cat did that way back in the late 90's. They found out the EPA's emissions testing procedures and the ECM was smart enough to recognize those specific conditions so they programmed it to run clean in them and dirtier in normal conditions. EPA figured it out and handed them their rears in fines and emissions schedule changes.

as long as there's a minimum of "what were they thinking when they built this thing" as you work on them.
GM came up with the "exhaust in the valley" idea and Ford decided to rush it to market first, International dumped them and they needed something asap. Hopefully Ford's second generation of this engine will be better.
