Do you have a high performance car, motorcycle, truck or vehicle, built a new engine, performed a tune up or installed a performance part? Try out this calculator get a rough estimate of horsepower. This calculator computes the estimated engine or motor horsepower from elapsed time. Elapsed time is the duration a vehicle takes to complete a run in a competition. This rich Internet app uses the quarter mile distance or meter track. Note: This is a rough and quick estimate of engine horsepower.
There are many factors which affect horsepower. Some examples are weather, temperature, humidity, elevation and fuel type. To get more accurate measurement of power rating, the engine should be placed under load using a dynamometer or dyno.
This will give a true measurement of peak torque and horsepower. When using SI units, the units are converted to standard units before the solution is computed. It should work on all devices smart phone, tablet, desktop, laptop, hybrids and operating systems. If any bugs, errors or issues are found, email the author using the address below.

The weight of the car, truck or automobile including the driver, passenger and accessories.This calculator has been designed around statistical averages based largely on sample data from Edmunds. Of course there are other variables that could be considered, but the times that are calculated should be reasonably accurate for most cars. In other words, if you're looking for a car that'll do in under 8 seconds, has over 39 inches of headroom, has AWD, a manual transmission, and over 30 mpg on the highway then you can actually search for exactly that.
Read more I created the calculator back in At the time I couldn't find anything quite like it so I built my own. It's a bit of a toy that I still use to this day. Since I created it, it's been linked to from hundreds of websites and I figure it's about time to explain how it works, why it works, and just what you can and can't expect from it. Note: Since this calculator is based on statistics from listed figures, it's important that you enter the data it asks of you and not whp numbers or race-ready weight.

If you can get at least a few, better yet would be 5 or more of each You can calculate driveline loss of each sample, add the losses of each auto trans car and divide by number sampled, repeat for manuals. Now you have scientifically resolved an average driveline loss that can fairly accurately predict crank power from rear wheel power or the opposite.

The drivetrain eats up anout 70 HP on an LS3. Want to reduce that I am going to dyno my car soon with the new driveshaft and rear cradle bushings I am betting it will reduce that 70 HP loss a bit.

Manuals, Literature, Workbooks, Brochures, Etc.The following two calculators can be used to estimate the engine horsepower of a vehicle based on the weight of the vehicle, elapsed time, and speed used to finish a quarter mile run.
Vehicle weight should include not only the vehicle, but also the driver, the passenger, and anything else of significant weight. To estimate peak horsepower, maximum work output should be applied from start to finish.
The results of all calculations are estimations only. This method uses the vehicle weight and the elapsed time ET to finish a quarter mile This method uses the vehicle weight and the speed at which the vehicle finished a quarter mile The speed used should be the speed attained at the quarter-mile point, not the average speed. When measuring the elapsed time or trap-speed at maximum work output of an engine, special precautions need to be taken. Firstly, all drivers need to know exactly what they're doing.
Inexperience can lead to repercussions, some of which can be serious and life-threatening. Secondly, do not measure elapsed time on a quarter mile on public streets or highways; driving over speed limits is illegal and attention needs to be focused on driving, not measuring times. These activities can endanger not only the driver, but other people as well. There are legal places to measure elapsed time, such as on drag strips, rural roads that are privately owned, and during special events that take place at raceways or airports.
What is the formula to convert wheel horsepower to flywheel horsepower on an automobile?
Thirdly, ensure that the vehicle is in complete working order, as taking a vehicle to it's limits entails certain risk. Check that tires are properly inflated and secured soundly, that airbags are functional, and that the engine is properly tuned and in good shape.
The idea of horsepower was created by the 19 th century engineer James Watt, who built some of the first steam engines.
Watt's work was remarkable, and to honor him, his name was given to the unit of power, the watt no, he didn't invent the light bulb, but his name is on every one.
Watt was working in a mine, using horses to pull wagons of coal. He wanted to determine how much coal a pony could pull in a wagon over a given length. He measured how many feet a horse could pull 22, pounds of coal in one minute. He then increased that amount to 33, foot-pounds in a minute, and called it horsepower.
It's a perfectly arbitrary amount, but it became the measure of how much work engines could do — no one had ever measured this before. So, imagine a horse pulling a wagon of coal out of a mine; with 1 horsepower of effort, the horse pulls pounds of coal feet in one minute.
Horsepower is measured by a dynamometer, which is a rotor in a housing. It takes a certain amount of power to make the rotor go around at a certain speed. If you put a car into neutral, and then floor the engine while it is attached to a dynamometer, the device puts a load on the engine and sees whether it can turn the load or how fast it can turn the load around.
If you run the engine at rotations per minute, rpmyou see how much load that turns on the dynamometer to calculate horsepower. Every engine has a peak horsepower — an rpm value at which the power available from the engine is at its maximum. You will often see this expressed in a brochure or a review in a magazine as " HP rpm". Gross horsepower is a measure of the work output of an engine on just a dynamometer, when the engine is not connected to the usual accessories apparent in a running car.
Net horsepower measures engine output when connected to belt-driven accessories such as water pumps, power steering pumps, and alternators. There are also parasitic losses in power caused by transmission drag and clutch or converter slippage that net horsepower takes into account.
As a result of powering these moving parts, net horsepower can be considerably lower than gross horsepower.Torque to Horsepower Converter is an online tool used in electrical engineering to calculate one form of energy into another form.
Horsepower is the measure of power that produces the mechanical output. Torque is a moment of twisting force that causes a machinery to rotate about an axis and it is usually represented in Newton meter N. Speed is the rate at which the object moves and it is calculated with respect to the time. In electrical engineering, torque to HP - horsepower conversions are highly required to rate the output in other related units.
Where this torque to HP - horsepower converters are largely employed to calculate the equivalent horsepower with respect to the input values of torque in Newton meter and speed in RPM.

If you know how fast your vehicle is traveling at the end of a quarter-mile run, you can calculate an estimated horsepower. That is, on the basis of your final speed through the traps, you can guestimate your engine horsepower.
For example, a 2, pound vehicle with horsepower should make it through the quarter-mile in If you know how long it takes your vehicle to run a standing quarter-mileyou can calculate an estimated horsepower.
For example, a 2, pound vehicle with a quarter-mile time of Note: The results you obtain from these calculators are just guestimations, though. Front-wheel drive cars are different from rear-wheel drive cars, and all-wheel drive cars are different still. Using trap speed and weight If you know how fast your vehicle is traveling at the end of a quarter-mile run, you can calculate an estimated horsepower.
