So obvious that both Ram and Ford are incredibly happy that the GM Duramax truck doesn't offer a 4.10 rear ratio because the gap would be a heck of a lot more than 15 seconds. Maybe even a whole minute + as so much more torque (another 10%) would be delivered to the drive wheels that turns them. Educated people know that it's TORQUE and only TORQUE that turns the drive wheels to the RPM desired or wanted. Higher rotation of the drive wheels means faster velocity of the vehicle as the drive wheel OD's are basically equal on all 3 trucks.

Rear ratios: 4.10 / 3.73 = 1.1 or 10% more torque delivered to the drive wheels. Maybe a little difficult for some of you to comprehend, but try!

Also obvious that GM has no need to offer a 4.10 as it already delivers more rotational force to the drive wheels of it's truck than either Ford or Ram.

Let the uninformed begin their BS rambling now! Just show clearly how much you don't really know or understand!

I haven't watched the video but were these guys running at wide open throttle or were they holding back to stay within the speed limit? If the latter is the case this is meaningless. If the former is the case this is still meaningless because the fastest one is only 15 seconds quicker than the slowest one. Power isn't really a distinguishing quality with these newer diesel trucks and that's been the case for awhile.

You hit the nail on the head! Even after warnings, it doesn't stop with these two.

Me Again,

DUH! HP is merely a theoretical calculation moniker derived from how fast the TORQUE applied to the drive wheels rotates them thus creating measurable RPM. HP is NOT a direct measurable value! Zero torque = Zero RPM and thus Zero HP could even be calculated. Even 1000 lbs feet torque with zero RPM = zero HP. There is Zero RPM if there's insufficient TORQUE to rotate the wheels. HP is merely a theoretical value calculation, not a measured value!

A "horse" does not have a given pulling or rotational strength value as there are vast differences is sizes and pulling strengths of all the various horses. A given size horse's pulling strength can be actually measured but which horse?

The more FORCE (TORQUE) one applies to wheel shaft, the more RPM's it will turn! No where is the word HP used or even involved to make the wheel turn to any RPM's!

TORQUE and RPM are measurable but NOT HP as it's only a theoretical calculation!

Read the article that meagain posted a link to. Power is the rate of doing work. Neither Rpm nor torque are needed to calculate HP. The formula: HP= torque x rpm/5252 is derived from the definition of horsepower(1 horsepower is the power required to lift 550 lbs 1ft in 1 second). If the formula involving rpm and torque were to be stated accurately it would read HP = torque x rpm x pi/16500.
