Some motorists get bored of driving a stock car over time. Therefore, they begin to tune their iron, that is, to make certain changes in the technical design, in order to thus increase the capabilities of the car. However, after the upgrade, you need to know how much power has been added. How do you measure engine power?
Necessary
Computer, cable, special software, dynamometer
Instructions
Step 1
There are several ways to measure engine power. It should be noted right away that all are inaccurate, that is, they have some kind of error. You can install special electronic equipment that will monitor the operating parameters of your engine online. Such equipment has an average error. However, it has a drawback - its high cost. Also, the installation of such equipment requires specialists, whose services cost a lot. It is worth noting that the maintenance of such expensive equipment can significantly exceed the cost of car maintenance. Installing this equipment is only advisable if you have a sports car that requires constant monitoring.
Step 2
There is also a less expensive way to find out how many "horses" are in your iron horse. It requires a computer, a special cable and a program for measuring torque. Such a program is always accompanied by instructions. Study it carefully. It describes in detail the order of all actions. You need to find a connector for diagnosing your car. Remove the plug from it. Connect your laptop. Download the program. You will need to drive several times at different speeds. The program will remember the indicators, and then automatically calculate the power of the power unit and indicate the calculation error.
Step 3
The most accurate way to measure engine power is to drive the car onto a dynamometer. To do this, you need to find a service that has such an installation. Drive your car onto the bench in front of the fan. The wheels should be exactly between the two drums. Fasten special belts to the supporting structure of the car. Connect the equipment to the car through the diagnostic connector. Put a corrugated frame on the exhaust pipe, which will remove gases from the box. Turn on the fan, which will simulate the resistance of the oncoming air. Now you need to accelerate the car as much as possible. At the same time, check the condition of the connecting belts. Make several attempts to eliminate the possibility of error. After each attempt, the computer will give you a printout showing the maximum speed and power.
