You mean you didn't feel any lag when your drove them at TMS? I felt lag in both my drag run and my towing run. Now it wasn't much but it was there. As Power Kid pointed out we don't know if it was turbo lag or lag from the drive by wire system. If people taking longer test runs are not feeling it then possibly Ford has done some reprogramming of the PCM.

You are correct, the smaller turbos will spool up faster than a larger one. On the 6.4 diesel Ford put two turbos, a smaller one to spool up fast and then the larger one kicks in.


Ford says "Virtually non existent". This doesn't mean none. It means very little which from my experience is what it has (and I do have experience with turbos) And possible, virtually everyone doesn't feel it.

 

My test "drive" was pathetic. We drove half-way around the TMS internal loop road, turned onto the I-35E southbound service road, drove maybe 1 mile to the main street, turned right, drove maybe 1/2 mile back to the TMS parking lot. I might have driven 2.5 miles total, never exceeding 50 mph, and that was for a very, very brief stint.

It was pouring down rain the entire time I was there, and I'm talking torrential downpour. I was running from tent to tent.

The drag race impressed me, but at a whopping 600 feet, it wasn't enough time to evaluate the truck. I spun the tires every time I got anywhere close to full throttle, as I did in the 6.2 HD truck I ran in the drag strip.

In all, it was nice to see the trucks, but I didn't get enough seat time to make a real judgment call, especially considering my limited seat time took place in a downpour.

I'm looking forward to a real test drive when the trucks finally reach the dealerships.

 

E) Ford's Navigation versus a Garmin? No contest. Toss the Garmin and get the Ford. You won't be sorry by a long stretch. Everyone is still trying to play catch-up in the car world. The Sirius Travel Link, Sync, etc... is absolutely the best. As a 50k+ miles a year driver, I wouldn't want anything else... and I have a 2 Garmins collecting dust.

Even thought it is WAY more expensive, I agree. The Ford NAV system in my wife's Flex is awesome.

 

It was back in Dallas Jan 4 thur 8th. It was at Grand Prairie Ford but I don't know for how long. Also if you lived around Dallas they would have brought it to your house and let you drive it again. I was 70 miles away so I didn't get too drive it again either.

 

I have driven Mustang SVO's, Turbo T-Bird's, Mitsubishi Lancer Evo's and a EB. I felt zero hesitation or turbo lag in the city or on the highway. I actually expected a slight turbo lag and then a boost of power but it wasn't there. It did pull smooth and fairly quick but it did not pull as hard as my Titan Crew Cab SE. My new 5.0 feel's as strong if not stronger than my Titan.

I believe the FX4 EB I test drove was specifically tuned to be smooth and not overbearing. It did pull throughout the power band but you could not feel any boost kick in.

I think this should have been Ford's next SVT truck.

 

You guys saying the EB is more sluggish down low compared to the 5.0 are on crack.

Compare the torque numbers and torque curve.

 

I said it felt lazy not sluggish. I have no idea why, like you said it doesn't compute with the torq numbers but that is what I felt and it could be they put 3.15 in the EB and 3.73 in the 5.0. Also remember the 5.0 i drove was lighter due being a 4x2.

 

I'm sure the FX4 Crew Cab I drove with 20's had a 3.73 diff.

 

I just built an FX4 Eco on fords website and the 3.55 were not even an option.

 

^Fx4's come with the 3.73.

 

For those that think the 5.0 pulls harder, especially down low, you need to take another test drive in the Ecoboost truck. There really isn't any comparison between the 2 motors. The Ecoboost is closer to the 6.2. In fact, when I drove them back to back, the Ecoboost feels even stronger from a stop. Both trucks I drove had the 3.73 rear. The 6.2 takes over though from about 40-50mph on than the Ecoboost. All of the new engines are great, so you really can't go wrong with any of them.

Also, for the guy that said the 5.4 pulls harder than any of the new motors? Maybe the 3.7 V6 that's it. The 5.4 3V is a turd, one of Ford's worst motors ever.

Lastly, if you guys like the sound of the 5.0, don't test drive the 6.2. Once I test drove my 11 Raptor, I had to have it and the rest is history.

 

Yeah, I know. I was referring to a previous post saying something about 3.15's being in an Eco. Someone somewhere on here said something about 3.55's in the Eco getting better fuel economy. I just wanted to say, they come standard with 3.73 and you can upgrade to the 4.10.

 

One thing to note about the feel/butt dyno tests of these engines. The EB and similar engines with flat torque over the same engine speeds usually don't feel quick. They don't build torque as engine speed rise like most people expect. So acceleration does not keep getting stronger as the RPM rises to some crescendo or peak. And the exhaust sound or lack thereof changes people's perception as well.

The facts are, the EB is quicker than the 5.0L, loaded and unloaded, in every test that has been done. Perception rules, though, and that is reality. Good to hear the 5.0L is that good.
