This drivetrain loss reference table shows the wheel horsepower for a range of engine (crank) horsepower values, assuming a drivetrain loss of 15%. Every figure is computed with the same engine that powers our Drivetrain Loss Calculator, so the numbers are exact.
| Engine (crank) horsepower | Wheel horsepower | Power lost |
|---|---|---|
| 50 hp | 42.5 | 7.5 |
| 100 hp | 85.0 | 15.0 |
| 150 hp | 127.5 | 22.5 |
| 200 hp | 170.0 | 30.0 |
| 300 hp | 255.0 | 45.0 |
| 400 hp | 340.0 | 60.0 |
| 600 hp | 510.0 | 90.0 |
| 1,000 hp | 850.0 | 150.0 |
| 1,400 hp | 1,190.0 | 210.0 |
| 2,000 hp | 1,700.0 | 300.0 |
How to use this table
Find the row closest to your engine (crank) horsepower and read across to the wheel horsepower. For a value between two rows, the real figure sits between them — or enter your exact numbers in the Drivetrain Loss Calculator for a precise answer.
Need a value that is not in the table? — the Drivetrain Loss Calculator does it instantly, for free, with the formula and a worked example built in.
