Q:

What is the difference between BHP and PS?

A:

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.

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.

    What is the difference between a turbocharger and a supercharger?

    A:

    The main difference between a turbocharger and a supercharger is the way the charger draws power from the engine. Superchargers are usually actuated by a belt that's connected directly to the engine, while turbochargers draw power from waste gases in the exhaust system.

    What are the specs on a NASCAR engine?

    A:

    As of 2014, NASCAR mandated specifications include a carbureted V8 engine with a maximum 5.9-liter capacity (358 cubic inches). The current limitations are designed to encourage the engine parity of vehicles, which generate an average of about 850 horsepower. Most NASCAR engines are built from scratch, with the average unit taking teams roughly 100 hours to assemble and ranging in cost from $45,000 to $80,000.

  • Q:

    What is the function of a cylinder head?

    A:

    An internal combustion engine's cylinder head performs several functions including housing the exhaust and intake valves, the fuel injector and necessary linkages, and passages for the fuel and air mixture. In water-cooled engines, the cylinder head also contains integral ducts and passages for the engine's coolant to facilitate the transfer of excess heat away from the head and, therefore, the engine in general.
