Estimate your drivetrain loss and calculate your engine's wheel horsepower using our simple calculator.
You can now use all of Motoristo’s tools and calculators directly from our new app on the Google Play Store (iOS coming soon).
The app lets you save and load configurations, and even works offline, perfect for when you're out in the garage or on the go.
Crankshaft Horsepower: 300 HP
Wheel Horsepower: 255 HP
Drivetrain Loss: 45 HP (15%)
* These are approximate values based on typical drivetrain losses. Actual losses can vary based on modifications, maintenance, and other factors.
The power value you want to convert, which can be measured either at the crankshaft (engine output) or at the wheels (what reaches the ground). Crankshaft horsepower is always higher than wheel horsepower due to power losses through the drivetrain.
Each transmission type adds different levels of power loss to the base drivetrain loss:
Note that these values are approximations and actual losses can vary based on:
