Haterade for everyone!!

[GoCougs]

You're looking at a single point.  You need to plot power vs vehicle speed in each gear and compare.  Given its arched torque curve, ecoboost has a narrower power band than the 6.2.  Ford also has 2 fewer gears.  The may have done a better job at gearing for 0-60 than Chevy, but gave up some acceleration performance at higher speeds, where extra cogs and a fatter power band give Chevy more flexibility.

Actually, I "looked" at three points in 1st gear for each truck . At anything past ~3,200 rpm the GM 6.2L produces more torque and when at full boil the Silverado is never below ~3,900 rpm (at least in the first 4 gears). Thus, from ~20 mph till top speed the Silverado is putting more torque (= thrust force) to the street.

Do you need a spreadsheet to show you the truck with more torque for half the rpm range has more power as well, which means faster acceleration for half of the rev range, which means it will leave faster and eventually get caught by the more powerful engine.

I will break out a spreadsheet colored with green paint if needed

So what point does the horsepower catch the torque and wins the race? 

[FoMoJo]

Or you could just admit that a TTV6 isn't some magical thing and save a lot of effort. But go ahead with that green paint splattered spreadsheet.

Not magical, not perfect...but the best of the rest.   Besides, the old Chevy pooprod is at the end of its development cycle.  EcoBoost is just at the beginning.

This is going to be good; definitely better than plagiarizing my annotation Internetry.

This fact alone is all ya need.

At most I'd say it's a tie. Especially considering maintenance.

[GoCougs]

Let me help you again...

...oh and thats right, the corvette with performance exhaust dyno is actually different!  Who the hell would have guessed a car engine with an optimized intake and exhaust would have more torque and power then a truck equivalent.


In conclusion, bazinga bitch

What?

Must have one hell of a high stall torque converter


Oh, and who the help cars about top end on a truck???

[GoCougs]

When torque > hp. Duh.

[shp4man]

I had no idea that this forum cared about trucks enough to go six pages discussing them!

I'm sure your Walmart engineering degree could figure this out.. So I saved you the time

[GoCougs]

JESUS.

[hotrodalex]

who the help cars about 0-60 on a truck?

[r0tor]

Probably more people then the number that care about 65-98 mph in a truck

[hotrodalex]

5.6 seconds vs. 5.7 seconds.

Such a tiny difference it's laughable.

The more important stat is 30-50 and 50-70, where the Chevy trounces the Ford by 0.4s and 0.7s, respectively.

I heart this thread.

Why is it I care.   Redneck racing?

It's just so interesting r0tor raged on the Chevy.

Butt hurt that badly the ecoboost wins?

I'm fine calling the motor that tows more, accelerates better, all while getting better fuel mileage.

Unless the Chevy has the 3.43 gears and kicks Ford's trash at all 3 of those.

If ifs and buts were candy and nuts, Chevy would grow a pair

It would probably top out at 88 mph then...and get about 12 mpg .

[hotrodalex]

The speed limiter should know the gear difference and still allow up to 99 mph.

And as already stated, 3.43s should improve city MPG in normal driving conditions and minimally affect highway (you'll just be able to utilize 8th gear more often)

Looking at specs the Silverado would hit ~270 mph in 8th gear at the 6,000 rpm red line so ~6% more gear probably won't be a problem .

Given that the Chevy is a bit faster with 3.23 gears 3.42 gears would be a :0.

EcoBoost just fails to deliver - it's a distinction without a difference + lag + big repair bills. Maybe EcoBoost Gen II will be different but for now, GM's pooprod wins the day.

[r0tor]

While we are discussing fairies and pixie dust, if ford would outfit the Ecobooster Rockets, the booster rockets could come online after the torque curve dies down on the class asskicking ecoboost 3.5L V6TT and then the engine driveling could disconnect and the F150 could be puddling along at 80mph at 0 rpms :o
