Who has the most hp.. And torque

Who has the most power... I've been checking and it seems that those that have big power, have big weight to go with it...

sooo.. who has the best pound per pound power..

we have 300 hp--660 torque..

my coach loaded..22,600... that's wet with all our gear

soooo..

22600 lbs divide by 660 tq =34.24 lbs per 1 ft lb torque

22600 llbs divide by 300 hp =75.33 lbs per 1 hp

seems to be one of the top ones out there because of the low weight it pulls


now lets go to GCVW... 30,000

30,000 lbs divide by 660 tq =45.45 lbs per 1 ft lb torque

30,000 lbs divide by 300 hp=100 lbs per 1 hp

lets see whats out there...

Just for comparison, on my F-53 22K chassis:

19,160 lbs loaded/457 ft-lbs=41.9 lb/ft-lb torque
19,160 lbs loaded/362 hp = 52.9 lb/hp

22,960 lbs combined/457 ft-lbs=50.2 lb/ft-lb torque
22,960 lbs combined/362 hp = 63.4 lbs/hp

However, you are running your torque and horsepower through 6 gears whereas mine is 5 gears and we both have different rear end ratios and tire diameters. The two engines also have differing hp-torque curves. So my above numbers do not really have any meaning when trying to compare them to yours.

I'm guessing your coach weighs in the neighborhood of 45,000 pounds, so at 87 HP per pound, that would give you about 8,000,000 HP total. I don't think anyone on this site even comes close to beating you!

We might have to regear the axle with 2.55s so the front wheels stay down.

Interesting topic. Mine is a teenie weenie ISBXT 350/750 in a 2010 Discovery which works out to:

GVWR 32000 91.42 lb/hp 42.67 lb/ft-lb

GVCWR 42000 120 lb/hp 56 lb/ft-lb

Never couldn't make it to the top of a mountain, but maybe I wouldn't be in first place
