But by how much? I get that turbos matter. Just like it should have beat the 3.5 Eco truck on paper, I'd love to see just how close it would be.

My old 14 EB with 3.15's would lead them both. That bugger was fast since it was RWD, and got the power down quickly. Even with a tune on it, my 16 feels sluggish compared to how that truck ran, just wish I had some hard numbers to go by on it. Would really like to test drive the new 10 sp trans to compare.

On a side note, I did go over 100 today passing a pair of semis.

Yeah...I hear sport mode adds almost as much as stickers. By short race you mean 30 ft?
Is there any publication doing metered tests that has ever had a 2.7 quicker to 60 or 1/4 mile than a 3.5 in same trucks/trans/ratios? (and the 3.5 has sport mode too..and could have a hidden sticker.)

The difference is that the 2.7 reaches its power at a much lower RPM than any of the other engines. That's why in shorter distances, 1/4 mile, the 2.7 will be faster. That's also why a 3.5 would start to pull away in a longer distance. And don't discount sport mode, it is a lot faster than normal mode.

Not really... you still get maximum performance out of the truck at WOT. But it remaps the throttle so it "feels" faster, and holds gears longer, so it may be a touch quicker on a street course versus normal mode having to downshift first. From a stop, at WOT, both will deliver the same power.

The 2.7 is slower in the 1/4 mile in identical trucks than the 3.5. close at the start but loses. show me a publication showing otherwise. 1/4 mile isn't that short when they both are almost at limiter at the end. If i'm wrong show me!
been wrong before.

TFL truck ran a bunch of the old 2.7 vs 3.5 vs 5.0 in what I believe was 1/8th mile races and consistently found the 2.7 fastest. Not sure if it still translates with the 10 spd and 2nd gen 3.5 though.

I'm still surprised that heavy 502a took the raptor with an additional ~100 hp despite the larger tires (which partially offset the 4.10s as well).

The Raptor is around 700 lbs heavier.

I'm really surprised that the Raptor was 700lbs heaver than the other truck. I guess that pano sunroof, tires, beefier suspension and other luxury items add up. But the results kind of make sense. A very general rule in drag racing is that 100lbs equates to about a 1/10th sec. 700lbs should mean 7/10th sec. Another very general rule is that 10hp is an extra 1/10th sec. The raptor has 75hp over the other truck? So basically a wash. Of course those rules doesn't apply when you're running 10s, but for a 15 sec vehicle, it's a relevant rule.

Roughly 3% per thousand feet of elevation in performance loss in a normally aspirated engine. So 18% loss of power in the 5.0
