That 2009 F150 might have been a lot heavier than the 5.0 truck, who knows there are so many variables to the equation.

And if the 5.0 really made 390/405 then the 6.2 is a complete waste of Ford's time seeing as the 6.2 makes horrible gas mileage and hurts the overall mileage rating of the company. A 6.2 on 31" tires would make excellent dyno numbers compared to the 5.0 engine.


Don't forget, that the Raptor come's with 4.10 final drive. The Raptor may come with 34.5'' tires, but the 4.10 gears help to close the gap and maybe the 5.0 was dyno tested with 3.55.


And looking at both dyno graph from 5star, the 5.0 actually make more torque with tuning then the 6.2

Anyway, time will tell if the 5.0 really make more power then Ford say, but right now those dyno sheet prove that Ford are lowering the numbers. They did the same thing with the Mustang GT 5.0

I think some of you have been smokin' crack . . .

There is no way the 5.0 will put out more torque than the 6.2. Anyone who believes that is insane. Although I agree Ford's torque curve overlays are not scaled properly, I am sure the numbers are pretty close and the 6.2 kills the 5.0. Yeah you can tune both engines but I call BS on any tuner that can get the 5.0 to out torque the 6.2. RPM's make horsepower, cubes (generally speaking) make torque.

Also, my 2000 F-150, the last F-150 I had and the one I'll compare my new 5.0 to since that is my reference point, put out 350 ft/lbs of torque at 2,500 rpm. A quick look at the Ford torque curve suggests the new 5.0 might put out 325 or 330 ft/lbs at that same 2,500 rpm. So for me, I may have to drive my new 5.0 500 rpm higher on average to get the same pulling power as my old 5.4. I can live with that.

Just found out my 2011 F-150 5.0 is going to be built the week of February 21. Yee-hah!

Anyone who has pulled 9,000lbs with a 5.4L will read that test and very quickly correctly figure out the 5.0L will easily out pull the the 5.4L. Its really that simple.

I'm not smoking crack.

I'm looking at 2 dyno sheet, from the same dyno, from the same tuner, stock vs stock, tune vs tune and the 5.0 actually make more torque then the 6.2 tune vs tune.Stock vs stock, the 6.2 is a little more powerful, but not that much.The 6.2 have 51hp and 54lb-ft more then the 5.0 per Ford numbers, but on 5star dyno it only make close to 9whp and 15lb-ft more... And the 6.2 was dyno tested with 93 octanes fuel, not 87 like the 5.0. 9whp doesn't equal 51hp and 15lb-ft at the wheel doesn't equal 54lb-ft.

Put technologie in any motor and what do you get, POWER. Just look at the Ecoboost power. Yes it's turbo, but it's still a 3.5L V6.

Son of a beech! Thats gotta be a reg cab short bed 2wd. But man, thats hauling the mail for a truck.

In regard to this whole conversation Im of the opinion that the 5 liter will trump the 5.4 under 98 percent of circumstances and I dont have hard numbers to back it up with. Its just an opinion. When more hit the street we will learn more about them. I know the Mustangs make 365-370 at the wheels bone stock and some even at bit more. I really think Ford has built a winner here comparisons aside.

Here's the 5 star tuning overlay. It's a bit rough because of the quality of the originals so I traced over the 5.4 and 5.0 stock torque curves.
You have to disregard the HP curve because the scales are different for HP and Torque for some reason on 5 stars charts. These are overlayed for the Torque curves only.

Light green is the 5.4 / Dark green is the 5.0

I wish someone who thinks the 5.4 has more lower end torque would post some dyno graphs to prove/disprove their theory. I agree that the 5.4 being a larger displacement should theoretically have more low end torque in an identical engine however this appears not to be the case as these engines are obviously engineered differently.

Can't argue on the those spec's, but we need a 5.4 dyno with a 6-speed (same gears, same tires, etc). But I agree, with the previous poster, the 5.0L will be a better engine most of the time until we get more vehicles on the road.

Ever notice how much better the 4.6 3v runs compared to the 4.6 2v ? Thats one big reason the smaller 5.0 4v runs with or better than a 5.4 3v.Those heads and extra cams make a big difference.I wonder what kind of HP and torque we would be seeing if the 6.2 was a 4v?

I don't get the issue here...shouldn't we be happy that the 5.0 does more with less? Good on Ford I say.

Take a look between the Vipers v10 vs BMW M5's V10. Similar hp, sure different tq but nearly 3 whole litres difference in displacement. Engineers, hoorah!

Correct. But is seems that those who bought a 5.4 and don't plan to replace it soon are trying to feel better if technology didn't pass them by.

Two totally different built engines. If the vipers were forced to stay tame by gov regulations, 750-800hp vipers from the factory would be the norm...

The issue is that the ones who do not have a 5.0 wish they did.In a few years when they have a 5.0 it will no longer be a issue and they will be saying their 5.0 runs as good as their old 5.4 just like the 5.4 runs better than the 5.8 that it replaced.The next generation of engines will use smaller engines that will out perform todays 5.0.Just look at the new 3.5 v6.Just because I have a 5.0 does not mean it is better than a 3.5 v6.

Note that the 5 Star Tuning graph is for a 2005 5.4L. Didn't the 2005 5.4L have 2 Valves per cylinder instead of 3.

2004-2010 have the 3V 5.4L V8.
2004-2008 = 300hp and 365lb-ft with a 4 speeds automatic.
2009-2010 = 310hp and 365lb-ft with a 6 speeds automatic.
2009-2010 = 320hp and 390lb-ft on E85 with a 6 speeds automatic.

The reason the 6.2 isn't way higher is simple. 4x4 vs 2 wheel drive. That's somewhere around 10% so that would give the 6.2 quite a bit more power.
