could this truck pull mountains with super b weights?

if u have to ask you probably know the answer DB.

 

There are places in British Columbia (and Alberta) where you will be knowingly unable to maintain 40 kilometers per hour and therefore technically you could be required to obtain a slow moving vehicle permit. A scalemaster could take you to town, especially when the motor displacement is on a plaque on the side of a Volvo. In actuality I don't think underpowered tractors are ever picked on by enforcers unless there is a crash, in which case your insurer may turn on you and ruin your life.

That little motor will cause you to be a highway safety hazard and in the winter you will be spinning out dangerously quickly. On the steepest grades in British Columbia (not on the major highways) you will run out of gears. Your fuel economy will be terrible because that little motor is not designed to pull such heavy weights at highway speeds. That's why Volvo makes a 16 liter motor. The chip set ("tuned") horsepower rating means nothing really. What matters is the ground-rated horsepower measured on a dynamometer.

At one point British Columbia had a commercial vehicle brochure suggesting (or regulating - I can't remember) minimum horsepower ratings (which used to based almost solely on displacement) for Super-B's.

 

So, I am quoting myself so I can argue with myself.

I can find no such regulation but apparently there is a mystery Memorandum of Understanding added to the BC Motor Vehicle Act somewhere that states that British Columbia agreed to a national MOU of "gross weight to horsepower of 150 kg/hp". So according to your chip-rated horsepower of 525-ish you would be legal to haul 78,750-ish kilograms. Of course there is no way on earth your 12 liter motor is going to be putting out 525-ish or even 465 horsepower measured on a dynamometer or actually pulling a Super-B. So, if you got rear-ended by a school bus the engineer's report would state that you were underpowered according to intent of the MOU.

 

yeah, i had always heard aboot bc requiring X amount of hp, but back in 99, we were hauling tridems with 350 macks and scales said nothing....loaded super b's could pass me uphill and DID.

 

Just for the fun of it ..... What are they claiming for torque on that setup...?

 

Stock 465/1650 according to Volvo.

Isn't it a minimum of 300 pounds per horsepower??? 500 HP x 300 Lbs. =150,000 lbs.
