That 6.2 was in a Raptor and in 3rd gear (not 4th). Not sure what size tires / gearing the 5.0 & Eco had, nor what gear they were in during the dynos.

I doubt we'll ever get a real 1-1 comparison anytime soon.. there's just not enough 6.2's out there.

The only video I have seen of a 6.2L in a non-Raptor on the track was a 2011 SCrew 2wd Limited with an aftermarket exhaust doing 14.6 in the 1/4. He was not completely stock and it is only one video so there is no telling if that is the best a 6.2L non-raptor can do or not given similar conditions. That is still very close to forum member SICKQK's 14.32 in his completely stock 2011 EB SCrew 2wd 3.73 and forum member bignfast's time of 14.55 in his completely stock 2011 SCrew 2wd 3.55. There is another member that was quicker than binfast's time in a completely stock EB SCrew(Geno51's @ 14.37), but he has a 4wd truck and that 6.2L Limited is 2wd if I am not mistaken.

Again, please post those vids if you got them, I would love to see them! I have no doubt we will see a bunch of non-Raptor 6.2L times very soon now that it is available in more trucks.
Nothing 'official', just what's on the web. I feel like a 100ftlb advantage is fairly large. There are three vids posted by the same guy that show a screw vs screw and they are very close, I would think it would be pretty obvious if one or the other had a significant advantage.

You and I both know that 1/4 mile times are only loosely coupled with hp/tq. Show me a 800hp Supra and I'll show you a 12 sec car, lol.
