Is All Horsepower Equal?

Which is better hp or torque?

Horsepower is how rapidly the vehicle can perform that work.

Of course, horsepower is tied to torque mathematically.

Horsepower equals torque multiplied by rpm, divided by a constant.

Because there is generally a limit on how fast you can spin an engine, having higher torque allows for greater horsepower at lower rpms..

How many rpm is 1 HP?

3600 RPMThe 3600 RPM, 1HP motor produces 1.5 ft. lbs. of torque at 3600 RPM. So if your 1HP pump was operating at 1800 RPM, the 1800 RPM motor would be producing 3 ft.

How fast is 138 horsepower?

What is a horsepower equal to?

Horsepower, the common unit of power; i.e., the rate at which work is done. … In the British Imperial System, one horsepower equals 33,000 foot-pounds of work per minute—that is, the power necessary to lift a total mass of 33,000 pounds one foot in one minute.

Why is it called horsepower?

James Watt, who invented steam engines, figured out a mathematical way to equate horses to engine power. Thus the term horsepower was invented. Watt measured the capability of a big horse to pull a load and found it could pull a weight of 150-pounds while walking at 2.5 miles per hour.

Is BHP the same as HP?

HP is the output horsepower rating of an engine, while BHP is the input brake horsepower of an engine. … B HP is the measurement of an engine’s power without any power losses, while HP is BHP less the power losses.

How much HP is 1600cc?

Today a modern non turbocharged 4 cylinder 1600cc engine produces about 120HP at about 5000 RPMs. 1600cc V-twin Harley Davidsons optimized for torque generate about 90HP while high reving four cylinder sport bikes exceed 160HP. Turbocharged 1600cc engines generate in excess of 160HP.

What horsepower is 5252?

One horsepower is equal to 33,000 foot-pounds of work per minute.
