Many drivers over time make various changes to the technical design of their car in order to increase its capabilities. After any upgrade, it is necessary to check how much the engine power has changed.
Necessary
- - computer;
- - cable;
- - dynamometer stand.
Instructions
Step 1
Choose the method by which you will check the engine power. Alas, they are all imprecise. Try installing special hardware to monitor your engine while online. It provides some of the most accurate results, but it also has one drawback - high cost. Also, to install such equipment, you will need the help of specialists, whose services cost a lot. Maintenance of expensive equipment will cost you significantly more than the cost of car maintenance. Therefore, it is advisable to install it only if you are upgrading a sports car, which requires constant monitoring.
Step 2
Use a less expensive method of measuring "horses" in an iron horse. Prepare a computer, a program for calculating the torque and a special cable. Such an application is always accompanied by instructions. Study it carefully. It contains a detailed sequence of actions. Locate the auto diagnostic connector and remove the plug. Connect your laptop and download the program. Next, you will need to drive at different speeds several times. The application will remember the indicators, after which it will automatically calculate the power of the power unit, indicating the calculation error.
Step 3
Drive the car onto the dynamometer, in front of the fan. Place the wheels evenly between the drums. Secure the supporting structure with special straps. Connect the equipment to the car through the diagnostic connector. Place a corrugated frame on the exhaust pipe to remove gases from the box. Turn on the fan to simulate the resistance of the oncoming air. Next, accelerate the car as much as possible, remembering to monitor the condition of the fastening belts. The computer will print a printout showing the vehicle's maximum speed and engine power.
