Easy...... you daily drive a 6.2 3.73 and have mentioned its characteristics before....... Better as a truck engine. I don't honestly care if you win by a length with your 6.2 in an empty drag race. At least the Ecoboost doesn't have to turn 4K plus like your 6.2 to do anything while pulling. Or getting off the line for that matter. It has tons of pretty well instant low end pulling power like a litte diesel that a naturally aspirated 6.2 with L92 heads has no hope in hell of creating. A lot more fun to drive IMO.

But then it depends what you want doesn't it? Rev happy wannabe racetruck or an actual pickup truck......

Apples to apples.

 

Exactly why my L76 is getting cathedral port heads and a radix, need low end to turn these heavy meats and yank stuff around

 

Bingo! My 05 needs the Radix mod.... well and really probably 4.56 gears to make it fun again. Even with only 30" tall tires, heavy, plus 4L80E and 3.73's is no fun off the line.

 

I think youd be surprised how much the radix will help. I doubt you would need gears since the radix ought to get you 2600 or so out of the stock 80e converter. Ive installed a few of them and even on a stock 60e converter(2000ish) turns em into a tire fryer. Plus they just sound awesome spun up

 

The topic was whether anybody has raced an Ecoboost, not whether they've towed vs one. I have never had any real complaints about the powerband on my truck (which was much improved by the tune), I've just wanted more, like most of us on this site. Now stock LY6 2500s, on the other hand, I have complained about lack of low-end before.

I agree that on paper the EcoBoost looks to be the winner for driveability while towing. However, I've heard less than desirable real-life feedback about their fuel economy and loaded performance vs the 6.2 GMs, so I will withhold judgement there until I am better informed.

 

Well if you want to talk just racing empty then look at the numbers. You have a 403 hp V8 against a 365 hp V6. Up top I would expect the 6.2 to start to pull. That however was not our experinece with the Denali pickup and the crew cab Ford. The 40Hp on paper advantage was not enough to start gaining ground. The Ecoboost raped the Denali out of the hole and then just held it's postion from about the 60 mph mark on.

I have heard a lot of things too..... they mean nothing. If you want a comparison line your truck up against one. Well put it back to stock first if you want to be fair. There is tons of supposed races out there along with the usual Youtube tripe... and I don't believe much any of it, one way or the other, lol. First hand works so much better and I have driven both trucks...... And yes, I didn't buy either of them.

 

I would definitely install the blower before worrying about gearing. It's just if I cheap out, or stay NA that the gears would be very advantageous to me.

I already get between 2500 and 2600 with the stock convertor just because of the additional weight I have added to the truck. I really doubt I could ever spin the tires ( without emptying the bed of course) but the pull would be awesome. As long as revenue canada sees the supercharger as a business expense ( it's my companies truck) I may very well have to do that!

 

I would love to line up with an Ecoboost, or even better a Ford 6.2. Unfortunately, I just haven't had the opportunity, and if I do I obviously won't be returning to stock just to get a better comparo I like to imagine that I haven't done much for performance other than cancel out the taller, heavier tires anyway. I have, however, lined up against a Tundra 5.7 4x4 crew and beat him decently twice.

 

You're not taking into account the avg power under the curve. PK numbers don't tell the whole story. I'm not a ford fan at all but they did a good job with the EB. If you really want to see as *** rapping race a NA 6.2 against one at 6000' elevation. The NA rig will lose 30% of it's power and the twin turbo's lose almost nothing.

 

Lol, I just popped in this thread to ask: Who really gives a flying f@&k about apples to apples comparisons? I personally never buy a car or truck and leave it stock, it's a sickness really. The EB motor appears to have good potential but I think it's kind of laughable that some of you think it has more potential than an LSX motor.

Not that it matters but I lined up a few times with a stock EB F-150 and he was running 15.30's. I talked to the guy and complimented him on his ride.
