It don't know about still being slow by today's power levels. Power levels have gone up, but weight has gone up faster and new trucks don't make torque like the blown 5.4 did. A new 410hp Raptor would struggle to beat a stock gen 1 L. Same story with the other brands. They market a big hp number, but lugging around 6k lbs with a torqueless engine with 33" rubber and lousy gearing makes for a turd.
Ummm, wouldn't quite agree with that.
You apples & oranges comparing a 4500 lb regular cab Lightning to a 6000 lb supercrew Raptor. If you compare a 2014 regular cab f150 to a 2004 regular cab Lightning, weights are fairly similar, and in the case of 2015+, they're even lighter with the aluminum body, aluminum blocks, etc.
Also a 411 hp, 6000 lb stock Raptor can keep up with a stock Gen 1 Lightning that weighs what 2,000 lbs less? My bone stock screw Raptor ran 14.9 @ 92, not a single mod, and crossed the scales at 6,300 lbs. Not too bad for literally 1 ton more weight lol. Digging up 1/4 mile times for stock gen 1 L's aren't they low-mid 15's?
Truck's don't make torque like the blown 5.4 did? While yes the blown 5.4 was one of the few engines of earlier days that actually made good #'s compared to the turd 260 the n/a 5.4 made, but the new trucks are making incredible power and torque for being N/A.
Gen 2 5.4: 380 hp @ 4750, 450 tq @ 3250 (or 360/440 for 99-00)
Raptor 6.2: 411 hp @ 5500, 434 tq @ 4500 (31 hp more, 16 tq less)
Yeah it's a bit more RPM, but it's also 2 more gears being 6 speeds. I can tell you first hand, the new trucks, 5.0, 3.5 EB, and 6.2, all feel way faster than their predecessors just from gearing alone despite being N/A with only slightly less tq at a little higher RPM.
Lousy gearing? That's the exact opposite! As mentioned that 6 speed makes a HUGE difference, 1st is such a low gear it kicks the trucks in the *** off the line. 2nd gear in those trucks is comparable to 1st in the gen 2's. My 00 HD even with the supercharger setup on it, even when it was mildly modded, had absolutely turd gearing being factory 3.55's with a 4 speed trans and 30" tall factory tires. My Raptor even despite massive 35's can launch out of the hole pretty good from an insanely low 1st gear in the 6 speed and factory 4.10 gears.
So long story short, yeah you can get a heavy truck, but same cab combo, weight is similar, if not lighter (2015+), gearing is right on the money especially with the 6 speed (and 10 speed coming) trans, and torque isn't all that shabby for being N/A compared to older s/c trucks, the gearing and hp makes up for the slight tq difference. Enough so that even the bigger screws can keep up with lighter regular cabs of years past.
Now modded, n/a never mods as easily as s/c or turbo, I'd definitely take a gen 2 powertrain for modding any day of the week. But stock for stock, the new powertrains are impressive and done right. Certainly a recipe now that could support a Gen 3 L between the capable powertrains, awesome trans, and light bodies & blocks.
