Horsepower = (Torque x RPM) / 5252.
A dynamometer can either directly measure torque output by measuring the force exerted on the rollers, or can directly measure horsepower by measuring the acceleration of a weighted roller. It then calculates the unknown value based on the RPM and the measurement.
You will see that HP and TQ always cross (are equal) at 5,252 RPM on the graph. This is because of the division in the formula above. Below that point, the torque is greater, and above that point, the horsepower will peak.
Other than seeing peak numbers and your power curves, you can use this information to help drive your car better. For instance if you are a drag racer and want to know where to shift, you can see at what RPM your horsepower starts to fall off and know to shift when the power starts to fall off. You can also see if you have any issues with your tune or other problems if there is any kind of weird activity on your graph.

Difference between horsepower and torque?
Torque is the measurement of turning force. A wrench applies torque to a bolt. A motor or engine provides torque to do work. Horsepower is the measurement of the work done or ability to do work. This is done by taking the speed the engine is operating at (RPM) and what torque it is producing and applying a formula to give a horsepower rating.
What is engine torque?
Toruqe is the amount of rotational force the engine generates. Horsepower is work performed in a straight line.
What engine torque?

What is Horsepower and torque 7.4l Chevrolet?
Horsepower and torque are two key metrics that describe an engine's performance. In a 7.4L Chevrolet engine, horsepower measures the engine's ability to do work over time, indicating how fast a vehicle can go. Torque, on the other hand, represents the rotational force produced by the engine, determining how quickly a vehicle can accelerate from a stop or climb hills. This engine typically produces significant torque, making it well-suited for heavy-duty applications and towing.
How do you calculate horse power of a steam engine?
Horsepower is defined as work done over time. The exact definition of one horsepower is 33,000 lb.ft./minute. Put another way, if you were to lift 33,000 pounds one foot over a period of one minute, you would have been working at the rate of one horsepower. In this case, you'd have expended one horsepower-minute of energy. There are other definitions but as a whole they say approximately the same as in energy consumed for actual work.
How much horsepower is 7 torque?
Torque has nothing to do with horsepower. It is purely a measure of force, whereas horsepower is a measure of how much work can be done over time.
Describe horsepower and list the three quantities needed to determine horsepower?
Horsepower is a unit of measurement that quantifies the power output of engines or motors, indicating how quickly work is done. To determine horsepower, you need three quantities: torque (measured in pound-feet or Newton-meters), engine speed (measured in revolutions per minute or RPM), and a conversion factor (for example, 5252 for torque in pound-feet when calculating horsepower at RPM). The formula for calculating horsepower is: Horsepower = (Torque × RPM) / 5252.
What about horsepower and torquein lawnmowers?
Horsepower and torque in lawnmowers are key indicators of their performance. Horsepower measures the engine's overall power output, affecting how quickly the mower can cut through thick grass, while torque represents the engine's ability to perform work, particularly at low speeds. Higher torque is beneficial for tackling tough terrain or dense grass, whereas horsepower is more relevant for overall speed and efficiency. Choosing the right balance of both depends on the specific mowing tasks and lawn conditions.
How much weight can a 80cc engine push?
There is not a direct answer to your question due to you are asking about engine size/displacement. The amount of "work" an engine can accomplish is related to the torque that is output from an engine. The amount of torque an 80cc engine can produce is also variable. For example, a screaming 2 stroke run at 12,000 rpm does not have much torque -- it relies on the engine momentum to do work. A 4 stroke 80cc engine would have more "torque" (but less horsepower) There is also a gearbox you have to include. A large reduction gearbox that turns slow for the high engine rpm could output hundreds of pounds of torque (foot pounds or pound feet) translating to pushing thousands of pounds.
What is the horsepower of a 2001 Ford F-150 with a 5.4 Triton v8?
The 2001 Ford F-150 equipped with a 5.4L Triton V8 engine produces 300 horsepower. This engine is part of the Ford Modular engine family and offers a balance of power and torque, making it suitable for both work and everyday driving. The horsepower output contributes to the truck's performance capabilities, especially in towing and hauling.
What is the difference between brake horsepower and horsepower?
The difference between brake horsepower and horsepower or wheel horsepower, they are the same thing, is that brake horse power is the power produced by the crank. The wheel horsepower is the amount of power delivered to the wheels. Brake horsepower refers to the method used to test the engine. A brake is attached to the engine and used to maintain the engine at a constant RPM at full throttle. The delivered power output is then a simple calculation of RPM times torque. Horse power is based on the average amount of work that a horse could do in a day. It is taken to be 746watts. well you guessed it engine output is also specified in kilowatts so divide by 746 and you have horsepower. As stated above it is all the same thing. There is a difference between advertised horsepower and brake horsepower. Advertised horsepower is what a manufacturer will rate its engine/automobile/machine to produce. Brake horsepower is the actual measured horsepower, for example, of a motor on an engine dynamometer.
What is the difference between torque and horsepower?
Horsepower - power over time, continuously used. You can only generate what you need or use.Torque- Power on hand, waiting for demand. Like a weight hanging on stick. It is there when you need it.Torque gets you going and Horsepower keeps you rolling.AnswerYou really should be asking, "What is the difference between torque and power?"Horsepower is simply the Imperial unit of measurement for power, usually used to describe the output (rather than input) power of a machine. These days, most countries use watts, which is the SI unit for power. Power is defined as the rate of doing work. In Europe and elsewhere outside North America, the output power of a car engine is measured in kilowatts, rather than in horsepower.Torque is the product of the radius of rotation and the force acting at right angles to that radius. So, torque is normally expressed in newton metres.The work done by torque can be determined by multiplying the force acting at right angles to the radius, by the circumference through which that force acts. If we know the time taken to complete the circumference, then it is possible to determine the power.
