BS. Your saying given proper maintance & some TLC my 5.4 will outlast yours based soley on the fact you've got more HP?! That kind of thinking is what is getting the Big 3 in trouble. You CAN produce more HP with the SAME displacement and they will last just as long!

 

Honda engines make great specific output (more power per given displacement), and are some of the longest-lived engines out there.


There's a lot of factors to take into account when you're talking about engine longevity. I think material quality and build tolerances contribute greatly, and if these things are top-notch then you can make good power and have longevity.

 

So am I to believe by the majority of these posts that nobody would have opted for the 6.2 if Ford had it available with the redesigned '04's?

Think about how many people Ford lost to Dodge because of the "Hemi". I'm willing to bet Ford could have sold these people an F150 if they had a better performance option in these trucks.

Judging by how many people are doing performance upgrades on the 5.4, the 6.2 would have sold well.

 

and do we really expect this from Detroit?

seriously?

 

Here is another problem: I bet ford will offer it as a third option. You'll have the 4.6L, 5.4L, and 6.2L to choose from when you order. This will kill sales for the 6.2L. Why? Same reason the V10 doesn't sell well - too big too inefficient. The 'middle of the road' option offers the greatest balance between power & efficiency. Truck buyers are not dumb.

 

Yes thats what I'm saying. Are you an M.E. ?

 

Well, that means your 5.4 was underengineered and is a pile. It doesnt take an M.E. to know that. The HP of an engine is not proportional of lifespan.

 

Horsepower is easy to get out of small displacement motors. Take the Honda S2000 = 240HP out of a 4 cylinder 2.0 (N/A), or the Acura TL = 270 out of a 3.2 liter V6 (NA), and even my modified '94 Probe, it makes 200HP out of a 2.5L V6(NA). By the numbers, these three cars have at least 20 more HP than my old '88 F-150 with the 302. However, if I swapped one of these small motors into my truck, it couldn't pull jack. The small motors can get the big HP pretty easy, but just don't have the displacement for making any serious torque.
I'm absoulutly not denying that HP is important in truck applications; I'm just quickly pointing out that Horsepower is pretty easy to get out of small displacement motors.
Next, just because you make 250 HP in a small V6 doesn't tanslate into usability in the truck catagory. My Probe makes peek HP at 6000 RPM's, the redline is at 8000 (I have the KLZE upgrade) what good is that in a truck? Maybe they [truck designers] sacrifice some of the HP in the design to appoint it to a more usable powerband?
You were comparing the HP per liter, try comparing torque per liter.. you'll see it is not much of a comparison at all, the 5.4 will blow the beemer out of that catagory.

 

I hear 'ya fordby4.... but I know there is a TON more power to be gained from the current lineup of engines. The brainpower is there to make it happen.

On the flip side... if HP is easy to get out of the smaller motors, why is the 500 getting a 3L that pushes a measly 203HP? Ford has ONE hot engine in thier arsenal... the 3.9L V8. 280HP with the capability to easly reach 310 with a few tweaks.

 

Yeah, forced induction or upping displacement are about all you can do to significantly increase torque.

HP just takes RPM, and making SOME torque at those rpm. Look at an F1 engine, tons of power (18,000 rpm), but not ton of torque.

 

Some of these guys are rambling on with the "I love my 5.4" crap because the 5.4 is as good as it gets with the F-150. If you only use what you need daily, the 4.6 is just fine; but most people opt for the 5.4L... Why? More power...

So, if Ford offered the followign choices.

6.2L Hurricane 350 HP, 400 lb./ft. torque @ 1,900 RPM
5.4L Triton 300 HP, 350 lb./ft. torque @ 2,400 RPM (Or what ever- I'm spitballing)
4.6L Triton 232 HP, 291 lb.ft. torque @ 1,800 RPM (Or whatever)

Most of the folks on this site would have opted for the 6.2L because it would have more power (quicker), more towing power (knowing ford) and, it woudl be the strongest F-150 you could buy.

That's why these guys want diesels in the F-150. (Power & fuel economy)

I don't buy into the whole small engine, more power genre'. I like big Detroit power, big cubic engines, and the rumble of an American V8. I don't care how much faster a 3.5L V-8 from Ferrari is, or a 4.4L V-8 from BMW is, or what have you.. In America, it has been- and will be about numbers. (289 Hi-Po, 302, 305, 327, 350, 351, 400, 427, 426 Hemi, 454, 455, 460.) Today its, 5.0, 5.7. 6.0, 7.4, 8.0, etc... To open up a hood and see it full of engine, is incredible.

Sure, high-tech has it's place; but, for sights & sounds, give me a strong, naturally aspirated, big cube American V-8.

If you take care of any engine, it will last a long time.
