When modified:6.2 vs 3.5 ecoboost 1/4 mile
Please don't turn this thread into an this engine is better than that engine etc. etc, I am just looking for some facts. There is not much info out there on the 6.2 in the regular f150, so I thought I would ask. I have read a lot on the raptor forums about this as well. Also, I know it is a truck and not a race car, but I appreciate any quick vehicle.
Stock for stock in the 1/4 this seems to be a drivers race. T or F?
Let's say both trucks are CCSB 4wd.
Eco has tuner, exhaust, Cai
6.2 has full exhaust, tuner, Cai
From what I have read, the ecoboost takes the crown in the 1/4 in this use case as well...possibly by a 1/2 second or more? On the dyno it seems that Hp would be close, but torque (the curve especially) would put the ecoboost way out front. T or F?
Does this change once the truck has bigger tires and a lift? I am also thinking no.
I am I the market for a new f150 and would like to try and figure this out. Honestly I want to be wrong just because I want the sound of the v8, but considering the power difference once modded, I couldn't choose the 6.2 as I would probably have to do heads and cam to be as quick as a basic bolt on ecoboost.

Adding a lift and larger tires will negatively impact performance and mpg.
The Eco wins for cheap power. The 6.2 is capable of ~480hp/480tq with bolt-ons and a good tune

I think the EB F150 is going to make much more torque than a N/A 6.2. We have a lot of good running EB trucks and the top 2 spots on the fast list. One truck, tune only goes 13.56 and another with tune, CAI, downpipe, exhaust goes 13.30.
Bigger tires and lift will make less power with both the EB and 6.2, because there is more weight/rotating mass.
A few examples or more modded 6.2's...
We've made good N/A power with a Raptor with our cams and bolt-on's.
402 RWHP / 409 RWTQ
Also made just over 600 RWHP with a 400ci stroker and low boost twin turbo kit on a slightly lifted Raptor with much larger tires.
another one with similar mods and no lift (more driving footage)

I'm not a smart man but I fail to see how two identical trucks with one having nearly a 100hp more can lose to a truck that's down a 100hp. Unless the 6.2 weighs that much more than an ecoboost.
On edit, I see where 402hp is the rear wheel on the raptor after some work. In that case, the race would be much closer and I could see the eb winning.

How important is gas mileage? The 6.2 is a damn reliable motor and at this point more proven but obviously it's not going to be the fuel sipper that the EB CAN be. Although if you plan on larger tires and a lift that advantage is gone anyway. Keep in mind a blower will pretty much just bolt on a 5.0 too so that's something to consider because you pay dearly to check the 6.2 box...or at least best I could tell when I built one up online.

For those asking, I am not talking about mpg. I think both lifted with tires they probably both get pretty similar numbers. Obviously the better mpg would be nice but I know the ecobbost without an economy tune of some kind is in boost a lot.
Yes I am talking basic bolt ons. Not cams or power adders.
as for the lift and tires question, I understand fully how the higher rotating mass effects power, but what I was unsure of was if it affected one more than the other.
To the wheels? Do you have a link because that would be impressive.

Edit: bolt-ons being full exhaust, CAI, tune
Both will be impacted equally but you 'should' feel it less with the modded Eco because it will have more tq.
