What is the meaning of horsepower?

horsepower. [ hrspour ] A unit that is used to measure the power of engines and motors. One unit of horsepower is equal to the power needed to lift 550 pounds one foot in one second. This unit has been widely replaced by the watt in scientific usage; one horsepower is equal to 745.7 watts.

Why is it called brake horsepower?

Traditionally ‘brake horsepower’ (bhp) has been used as the definitive measurement of engine power. It’s distinct from horsepower because it takes into account power loss due to friction it’s measured by running an engine up to full revs, then letting it naturally slow down to a dead stop.

Is higher BHP better?

Brake Horse Power (BHP), on the other hand, gives you a much better indication of acceleration, simply because it denotes the amount of energy your engine produces in unit time, and this energy goes in increasing your car’s speed in the same time interval (assuming no air drag and all that).

Does higher horsepower mean faster?

The power produced by an engine is called its horsepower. In physics, power is defined as the rate at which something does work. For cars, horsepower translates into speed. So if you want to go faster, and get up to speed quicker, you need more horsepower.

How much HP does a funny car have?

Horsepower claims vary widely—from 6,978 to 8,897—but are probably around 8,000 HP. Supercharged, nitromethane-fueled motors of this type also have a very high torque, which is estimated at about 7,000 ft⋅lbf (9,500 N⋅m). They routinely achieve a 6G acceleration from a standing start.

What is the fastest Funny Car?

TOPEKA, Kan. (AP) — Robert Hight shattered the Funny Car speed record at 337.66 mph Friday in the lone round of qualifying in the rain-delayed NHRA Heartland Nationals.

How fast do funny cars go 0 60?

A top fuel dragster accelerates from a standstill to 100 mph (160 km/h) in as little as 0.8 seconds (less than one third the time required by a production Porsche 911 Turbo to reach 60 mph (100 km/h)) and can exceed 280 mph (450 km/h) in just 660 feet (200 m).

How long does a Top Fuel engine last?

The life of an engine of this sort is typically 11–12 runs in a dragster it is completely replaced, but after each of those passes it will be torn down and rebuilt.

How much does nitromethane cost per gallon?

At the end of the 2018 NHRA Mello Yello Series season it cost $1,195 for a 42-gallon drum of nitromethane. During the season-opening Winternationals at Pomona, Calif., a 42-gallon drum of nitromethane cost $1,428.

How much HP does nitromethane add?

Cars typically need about 15 pounds of air to burn one pound of gasoline. With nitromethane, you only need 1.7 pounds of air. Drag racing motors are big, with an average engine displacement of 8.9 liters. When supercharged, they can produce about 6,000 horsepower.
