2009 Ford F-150: 2009 Ford F-150 5.4-Liter V8 Power Ratings Leaked On To Internet

 

Uh Oh.....

 

Hope it's tougher than that..

 

Nice scoop! The numbers are about what I expected. Not as high as the Tundra's but peak torque is reached at a much lower RPM on the Ford which is better for a truck.

 

I still don't get why people are making such a big deal about HP numbers. 320HP at 3200RPM vs Toyota's 381HP at 5600 RPM is a big deal. Yes, they have 60 more HP, but at 2000 more RPM. You can watch the fuel gauge go towards "E" in that Yota. The improvement in torque is impressive. Especially at a lower RPM than before. I am sure this has a lot to do with the "open valve injection" they are talking about.

 

The 5.4 says 320HP @ 5200 rpm not 3200

 

320 h.p sound's right and was my predition based on the fact that FORD said nothing,
You will never get more press on a new truck than when its NEW !
If they had something worth bragging up they would have.

What marketing wizzard release's a New Model with a ALL V-8 Line up with the lowest H.P numbers at this time in history. and new powertrains (?)coming years later.

 

Basically what I expected in the HP realm. Like most, I guessed around 310-325hp. Now I do dislike the 5200rpm portion. I love the increase in lb-ft TQ, from the current 365 to 390. Not too significant, but brings the 5.4L up/near other makes.

With this added boost and the 6spd trans, we'll just have to see how she performs. Some grip the 6spd gear spread from 1-2 is too large, but wonder if this boost and computer will compensate for this gap. Sounds like DearbornDerek was somewhat impressed with the 4.6L, so wonder what he'd think about the 5.4L.

 

The 6R80s 4.17 to 2.34 1-2 is better than 2.84 to 1.55 in the 4R75E, the Tundra 6-speeds 3.33 to 1.96 1-2, or the GM 4L80Es 3.06 to 1.63 1-2.

The 4.17:1 1st will allow for a much harder step-off, and work great in getting big loads moving from a dead stop.

Assuming the new F150 has a roughly 5500 rpm shift point (seems logical if Ford is quoting peak horsepower at 5,200 rpm) that means with the 6R80 1st gear will pull to 32 mph, and 33 mph in 2nd gear equates to 3200 rpm, which is within 300 rpm of the new F150s peak torque.

So, the 6R80 (4.17, 2.34, 1.52, 1.14, 0.86, 0.69) with a 5500 rpm upshift, 3.73 gear and a 30" tire puts the:
1-2 @ 33 mph and 3200 rpm in 2nd
2-3 @ 57 mph and 3600 rpm in 3rd
3-4 @ 88 mph and 4200 rpm in 4th
4-5 @ 117 mph and 4200 rpm in 5th
5-6 @ 153 mph and 4400 rpm in 6th

Compare to the 4R75 (2.84, 1.55, 1.00, 0.7) still shifting at 5500 rpm even though they actually shift at 5,000 rpm:
1-2 @ 46 mph and 3000 rpm in 2nd
2-3 @ 86 mph and 3600 rpm in 3rd
3-4 @ 133 mph and 3900 rpm in 4th

The Toyota Tundra 6-speed (3.33, 1.96, 1.35, 1.00, 0.73, 0.59):
1-2 @ 41 mph and 3400 rpm in 2nd
2-3 @ 67 mph and 3800 rpm in 3rd
3-4 @ 97 mph and 4100 rpm in 4th
4-5 @ 132 mph and 4050 rpm in 5th
5-6 @ 180 mph and 4500 rpm in 6th

The GM 4L80E (3.06, 1.63, 1.00, 0.70):
1-2 @ 43 mph and 3000 rpm in 2nd
2-3 @ 81 mph and 3400 rpm in 3rd
3-4 @ 132 mph and 3900 rpm in 4th

I'll take the 6R80...

 

Sorry about the previous post, it must have been my dyslexia kicking in.

 

WOO-HOO the F-150 now produces as much torque as a Dodge station wagon.

The 5-7-liter HEMI V-8 engine provides...390 lb.-ft. of torque @ 4000 rpm.

 

Dude I hope you don't get into trouble for this...

 

Ha ha, I hope not!

That would be wild if it was me who blew the door off Fords secret numbers..

I just hope I don't get sued. haha

 

That was your picture wasn't it? I wonder were they got all the other info from? Holy crap did you read the pickuptrucks website? They even said that "Let's just say another person with a camera phone has revealed news that Ford has yet to officially confirm, on the forums of our good friends at Ford-Trucks.com. " I didnt know they watched our sites like that...


P.S. Were are they getting this from? "The 5.4-L V8 uses Ford's new 'open valve injection' technology. As the name suggests, open valve injection injects fuel into the cylinders while the intake valves are open (instead of closed like during conventional combustion cycles). The incoming air improves the mixture of air and fuel before the 'charge' is ignited. Ford says the result is increased horsepower during towing, higher RPMs, and an improvement in emissions from the more efficient burn."

 

Heck, if you click on the ford-trucks link on both jalopnik & pickuptrucks.com, it brings you to this post:

Kind of scary.
