Ford vs Chevy vs Ram HD DRW Drag Race
3...2...1... Let's Go! Enjoy Link BTW... Since TFL has their Ram truck hopefully we can see an Ike pull

^^^It’s interesting that the 2024 Duramax appears to be an over achiever when you consider how it almost kept up to the much higher rated HO Powerstroke. If, however, you compare the 2024 Duramax towing 27000 lbs to the 2020 regular output Powestroke towing 30,000 lbs up the hill, the Duramax doesn’t look overly impressive.
Because the Duramax has a little higher rpm band than the Ford you’d expect both the 1050 lbft Powerstroke and the 975 lbft Duramax to be making about 400 HP at the point where they would downshift…. 2250 rpm for the Duramax and 2050 rpm for the Powerstroke. At 2600 rpm the Powerstroke is rated at 475 Hp and the Duramax 470 at 2800 rpm so we’d expect the two engines to pull very similar.
The rear wheel power required to pull a load up a hill is the sum of three values: the power required to overcome drag + power required to overcome rolling resistance + power required to lift the weight from the bottom of the hill to the top. Because both the 2020 Powerstroke and the 2024 Duramax were pulling different trailers up the hill we can’t say exactly but it would seem reasonable to say that it would take slightly more power to overcome rolling resistance on the 30,000 lb trailer vs the power to overcome rolling resistance on the 27000 lb trailer. If the power required to overcome rolling resistance at 44.7 mph on the 38500 lb combination is 60 hp it would require very close to 55 hp to overcome rolling resistance with a 35500 lb combination at 44.7 mph. It would also seem reasonable to expect the power required to overcome air resistance at 44.7 mph with the two trailers to be somewhat similar and not a huge number …. say 50 hp in both cases.
The 2023 Powerstoke would have averaged 45.7 mph which would have required very close to 56 hp to overcome rolling resistance and another 51 hp to overcome drag.
The power required for the 2020 Powerstroke to lift 38500 lbs from the bottom of the hill to the top (2300 feet) in 620 seconds can be easily calculated and is exactly 259.7 HP.
The power required for the 2024 Duramax to lift the 35500 lb combination the 2300 feet in 620 seconds is exactly 239.4 HP.
The power required for the 2023 Powerstroke to lift the 35500 lb combination 2300 feet in 607 seconds is precisely 244.6 hp.
So the 2020 Powerstroke made somewhere close to 370 rear wheel hp to pull its load up the Ike.
The 2024 Duramax made somewhere close to 344 rear wheel hp to pull its load up the Ike.
And the 2023 high output Powestroke would have made very close to 352 rear wheel hp.
