All horsepower and torque numbers advertised on our website are provided by the crate engine manufacturer. These numbers were achieved on a professionally operated dynamometer to compensate for variables like altitude, temperature, relative humidity, vapor pressure, and barometric pressure, all of which impact measured horsepower and torque. If you do not purchase a complete crate engine, the selection of additional components, and how those components are tuned, will have an impact on measured horsepower and torque. Ignition and fuel system components, as well as the fuel octane and quality of the fuel that you select, will impact the numbers. Please understand that, while horsepower and torque numbers are repeatable within reason, they will most likely not be reproduced identically.
