BHP stands for brake horsepower and PS stands for Pferdestärke, or horse-strength in German. Both units describe the power output of a vehicle's engine.Continue Reading
Both units are widely used in the automotive world. BHP is less than the total horsepower of an engine and looks at the amount of energy remaining after the alternator, water pump and other systems have been powered up. BHP is measured at the road wheels, rather than at the flywheel, and the higher the BHP, the more powerful the engine.
PS is still commonly used by car makers from Germany and other countries, although it was replaced as the official EU measurement of engine power by kW or kilowatts in 1992. One PS is the equivalent of about 98.6 percent of 1 BHP.Learn more about Engine
The LS2 engine's specifications include being able to generate up to 400 brake horsepower at an engine speed of 6,000 rotations per minute and 400 pounds feet of torque at 4,400 rotations per minute. The LS2 engine has a displacement value of approximately 5,967 cubic centimeters and has a compression ratio of 10.9:1. The LS2 also has a fuel capacity of 6 liters and is considered the first engine of General Motors' Generation IV engines.Full Answer >
Brake horsepower refers to the leftover energy after powering parts, such as the water pump, alternator and gearbox, while horsepower refers to the total engine output. HP is measured at the flywheel, while BHP is measured at the road wheel.Full Answer >
The torque and horsepower specifications for a Chevy 5.3-liter gas engine range between 310 to 326 horsepower and between 335 to 348 pounds per feet of torque. When it runs on regular unleaded gas fuel, the Chevy 5.3 -liter engine can only generate between 310 to 320 horsepower.Full Answer >
Relatively inexpensive ways to boost a car's horsepower include running higher-octane gasoline and improving the car's intake and exhaust systems. Improving the intake systems allows the car to have a richer fuel-air mixture from the additional oxygen brought in from the new intake, while exhaust improvements allow a car to get rid of exhaust more quickly and to produce more power. Tuning a car's engine control unit can also yield power gains in many automobilesFull Answer >
