Question:

Brake Horsepower VS Horsepower VS Wheel Horsepower?

Tell me all about them. I know that wheel HP is the power at your wheels. But is brake HP like the power at the flywheel? And if so is it before or after all the loss from things like the alternator, power steering pump, AC etc. thanks:)

Answer:

take it to a car shop and get it checked out.
Normal operation for a Hyundai alarm. BTW, Hyundais are the least stolen vehicle because nobody wants them.
THe company does this on their cars as a saftey feature My car did this so and it made me so mad! but my mchenacly inclined nephue fixed the problem in an hour during a family reunion, it kept him busy. but ask around see if theres a tweak u can have put in
well a degree in automotive engineering would help you understand all these values. brake horsepower is as it says braking the horsepower to a stand still. on a rolling road. the old measurement fo actual horse power used to be 100cc per horse power. then we have the brake horse power at the fly wheel measured in a laboratory situation not actually on a car or van or lorry but when the engine was being tested before production of the new vehicle. so all this is pretty meaningless to be honest. the vehicle can be put on a rolling road and strapped down and readings taken but what might have been 170 bhp at the rear wheels when new by the time it gets to be 5 years old could be just 30 BHP. yes engine and transmission condition will effect it's performance to a great degree.
Brake horsepower (BHP) is the amount of power generated by a motor without taking into consideration any of the various auxiliary components that may slow down the actual speed of the motor. Sometimes referred to as pure horsepower, brake horsepower is measured within the engine's output shaft. Depending on the configuration of the engine, the point on the output shaft that is the focus of the measurement is the engine dynamometer. The reference to this type of horsepower measurement as brake horsepower has its origins in the braking systems that were used on some of the first automobiles in the early 20th century. In many instances, cars were equipped with a hand brake that would slow the forward projection of the vehicle. This same hand brake was also used in the manufacturing process to gauge the amount of torque created within the motor, making sure the output was within acceptable limits. In the actual calculation of brake horsepower, it is necessary to consider the total load of the motor. This means disregarding any drain on the power that is due to the water pump, generator, or the gearbox that work in conjunction with the motor of the vehicle. The amount of power loss that occurs due to the action of various belts and pulleys is also added back into the base figure, making it possible to determine the true amount of pure horsepower being generated by the motor.
