While I don't understand the implications behind unsprung weight, I do know that less is better than more.
I had thought it was more to do with suspension and handling than with acceleration, but that's beside the point.
What I wanted to bring to this conversation, and hopefully someone smarter than I can help explain this, is the distance covered by 44" vs something like 32" diameter tires.
Recall circumference is 2 pi r, so
44" = 2 x 22 x 3.14159 = 138
32" = 2 x 16 x 3.14159 = 100
Wouldn't each revolution of the tires would be something like 38% further down the road.
If nothing else changes, wouldn't it feel like you lost almost 40% of your power?

Changing gears to a lower ratio should correct this, but what ratio would that be?

 

That is essentially it. For that size tire, to maintain "stock" RPM vs. Speed, you would need right around 5.1:1 gears.... For the half ton though, best you are going to do is 4.88..... and you will be breaking parts on pretty much a weekly basis...... For that size tires, you would be REQUIRED to upgrade to at least D60's front and rear...... (and then the right gears would be available too.....) Then, the trans/transfer case would become the weak links....

 

i understand the difference between horsepower and torque. sorry that a threw the term "horsepower" around. all i wanted to no was how much of a power lose you would feel with as close to stock gearing as you could by adding that much weight especially since the weight is being moved farther from the center so it has more centrifugal force behind it. just a simple question. lol didnt mean to **** anyone off... i also understand that you would want to over gear since you are adding so much weight to make it seem like you have the same amount of power. just curious thats all...

 

Just put a forced induction system on it, and be done with it. Plenty of power to turn those monster meats.

 

i think a leaf spring swap is enough modification for right now...

 

Yer no fun.

 

i got a 5.9 and with the big tires i slammed the gas and bogged rite down till it just bout died it dont like that big a tires espicially dead stop up hill

 

Not angry at all...just want to emphasie a point or two.

Lets be honest, most people want to modify thier trucks with an big desire to have things look or sound a certain way and a many have a minimal understanding of the consequences if the job isn't done correctly. Willingness to compromise or "live with" those issues causes them future problems.
So knowing and explaining the differences between horsepower and torque can help other folks who haven't really understood the difference.
Same with things like unsprung weight (which can effect handling too) and bump steer.
Or scrub steer....

 

yeah no hard feelings. but a big lift and tires are in the near future. just curious to see what the drive ability would be like...
