Horsepower has no "direct" relation to the speed of the vehicle with the exception of a ram air intake.
-Ram air intake/hood scoops use the vehicles speed to force more air into the engine, increasing it's horsepower. This effect is only measurable at high speeds >60mph.
Horsepower's relation to the vehicles "aerodynamic drag" has a direct affect on the vehicle's speed. Meaning it takes a certain amount of horsepower to sustain a certain speed of a vehicle with a certain amount of drag. It's a "non-direct" relation because a car with the same horsepower can go faster if it's drag coefficient is lower( aerodynamics improved). Horsepower's relation to vehicle drag can be seen in that it takes 4 times the current horsepower to double the current top speed.
An example: If a car goes 100mph with 125hp, it would take the same car 500hp to go 200mph.
"An engine doesn't produce horsepower", horsepower is just a calculation of the amount of torque an engine produces over time, in the form of "engine speed".... not vehicle speed. If you can maintain/increase torque output of an engine as rpms increase... Horsepower will also increase. The equation to calculate Horsepower is Torque x rpm / 5252.
An example:
An engine that makes 300 ft-lbs. of torque at 4500rpms 300x 4500/5252 = 257hp at 4500rpms.
If the engine can maintain 300 ft-lbs at 7000rpms the horsepower would be up to 400hp.
What else can I help you with?
How can I calculate the horsepower of a vehicle based on its 0-60 time?
To calculate the horsepower of a vehicle based on its 0-60 time, you can use the formula: Horsepower (Weight of the vehicle (Speed in mph)3) / (Constant Time in seconds). The constant value typically used is 375. This formula takes into account the weight of the vehicle, the speed achieved during the 0-60 time, and the time it takes to reach that speed.
What is the maximum power speed of the vehicle?
The maximum power speed of a vehicle refers to the highest speed at which the engine can deliver its maximum power output. This speed is typically reached at the engine's peak horsepower RPM.
How much horsepower does a 1968 olds 350ci?
Horespower relates to the speed capacity of an engine and thus how fast the vehicle can go. The horsepower of a 1968 Olds 350ci is approximately 350 hp at top speed.
How much horsepower does a 2007 Yamaha grizzly 350 have?
Its total weight when tank is full is 522 lbs and its top speed is 43 mph. Horsepower of this vehicle is 3.24.
How fast is 15HP in km?
15 horsepower is approximately equal to 11.2 kilowatts. However, horsepower is a unit of power and cannot be directly converted to speed in kilometers. Speed depends on additional factors such as the weight and aerodynamics of the vehicle.
One horsepower equals how many miles per hour?
Horsepower doesn't determine speed. Even with the weight of the vehicle, climate (road conditions, etc.) and every other factor, horsepower still doesn't translate to an exact speed, but rather a potential amount of power that can be applied.
Does wheel size affect horsepower?
No. It effects the vehicles speed, and how the horsepower is used. It take more energy to move larger wheels, so the vehicle will feel less powerful and because the larger wheels take longer to roll, the vehicle will be slower.
How fast is 250 horsepower?
The speed of a vehicle with 250 horsepower will vary depending on its weight, aerodynamics, and other factors. Generally, a car with 250 horsepower can reach speeds of over 100 miles per hour and can accelerate quickly.
How can one determine the power to weight ratio of a vehicle?
To determine the power to weight ratio of a vehicle, you need to divide the vehicle's power output (in horsepower or kilowatts) by its weight (in pounds or kilograms). This ratio helps to understand how much power the vehicle has in relation to its weight, which can affect its performance and efficiency.
What is 4 hp in mph?
Horsepower (hp) is a unit of power, measuring the rate at which work is done. It is not directly convertible to miles per hour (mph), which is a unit of speed. The relationship between horsepower and speed depends on various factors such as the vehicle's weight, aerodynamics, and efficiency. To determine the speed in mph produced by 4 horsepower, you would need additional information about the specific vehicle or system in question.
How do you use gear ratio to increase horsepower?
It doesn't work that way. The gear ratio determines what speed the vehicle is running at when in the (torque) powerband.
If the frequency of a wave is 200KHz the speed is 300000000ms what is the wavelength?
Use the relation: speed = frequency x wavelengthUse the relation: speed = frequency x wavelengthUse the relation: speed = frequency x wavelengthUse the relation: speed = frequency x wavelength
