2009 F-150 5.4L Preliminary Dyno Results!
Hey all...
Finally got back from Utah and needless to say, I AM EXCITED! ![]() The new 2009 F-150 is running awesome and actually looks to be making a bit more power than the earlier 2004 to 2008 versions. From what we've found so far, the only major difference under the hood is that the air filter housing has been relocated directly behind the driver's headlight and now uses a LARGE 12" x 12" pleated panel filter. This is definitely helping airflow. As you well know, the new platform sports a new 6-speed automatic transmission which now has its own controller which is separate from the ECM. The ECM itself has been updated to a new, faster processor as well. Fortunately, the tuning is quite similar and we were able to get the base tuning done without any difficulty. Here are the preliminary results: Test Conditions:
Horsepower Only ![]() Torque Only ![]() Horsepower and Torque ![]() Horsepower, Torque and AFR ![]() As you can see, the biggest gains were not on the top end but in the midrange... which is where you really need it! Notice that the stock AFR curve does not allow any WOT enrichment until about 4500 RPM! And you wonder why the trucks are always so sluggish off the line. ![]() ![]() I also included an additional dyno plot which show without question that removing the snorkel does, in fact, improve the performance of the vehicle, particularly above 3500 RPM. Based on calculations, removing the snorkel picked up 7.5 HP and 7.6 Ft./Lbs. These figures are very respectable, especially considering that we had already made a significant gain with tuning. Unfortunately, I didn't have time to retest the vehicle with the Performance calibration, but I would certainly expect to see similar improvements with the same modification. ![]() Needless to say, we are really excited about the results, especially since we only ran 85 Octane fuel. We will be doing some (relatively) sea-level testing here in the next week or two along with 93 Octane fuel testing and fully expect to see even better results. We'll keep everyone posted on the results as development progresses. Stay tuned... ![]()

Hey Bill, I am really impressed now that i can see the results on paper, are the 08 5.4 curves respective of these? Much smoother power and torque curves and also a huge gain in the midrange. Hats Off to your abilities . Jim

Jim,
The 04 to 08 dyno curves are similar, although are a little bit lower than the '09. I'll try to see if I can dig up some of the older plots we did on the 2004 and 2006 trucks for comparison. ![]() ![]() ![]() Take care.

Great information Bill! I too, would like to see the curves for 2004-2008 engines!

I thought the 07-08's are a bit stronger than the 04 thru 06's? I know they have more free flowing exhaust manifolds!

That's a nice improvement...
but that AFR graph of stock is a bit scary...

I remember a certain brand of model airplane engine I had when I was a kid that was very good at destroying itself as the fuel in the tank ran out. It would suddenly start running quite lean, the RPMs would increase then drop slightly and it would sound "weak". Then, the crankshaft would fracture! ![]() - Jack Last edited by Jackpine; Fri, January 23rd, 2009 at 03:08 PM. Reason: Entered correct A/F ratio for E10 |

LOL that's an interesting design...
run out of fuel? Bang LOL I'm thinking this was ford's engineer's idea to help fuel economy...

Despite the fact that 14.64:1 AFR is stoich for gasoline, this is NOT where peak torque is made. Under full load, peak torque occurs around 11.8:1 and peak HP is closer to about 12.6:1. Cruise conditions are quite a bit different and can run upwards of 15.0:1 without technically being "lean", although again this doesn't necessarily equate to the best fuel economy or performance.
