Bhp refers to the power of the engine measured at the crankshaft, while wheel horsepower refers to power measured using a chassis dyno at the wheels, which inherently accounts for drive train losses. A high-horsepower bike is typically pretty high strung and built for speed. On the other hand, BHP, or brake horsepower, refers to the power output of an engine measured at the engine's crankshaft, not including power losses due to auxiliary parts, making it a more precise measurement of an engine’s raw power.

It is the “Q Δp” version of the fluid horsepower equation. So in this scenario: Car 1 has 150 HP and 250nm torque Car 2 has 180HP and 200 nm torque What will happen in terms of differences in top speed and acceleration as car 1 has more torque but car 2 had more horsepower? Thanks. It isn't perfectly linear or 79 votes, 62 comments. There’s a world of difference between max HP out of an engine regardless of Ill effects vs maintaining the original drive ability but enhancing torque across the powerband.

Commonly measured in HP and kW. Basically horsepower (and weight) will determine how fast a bike accelerates when you're at full throttle at high revs, the relationship between horsepower and torque gives you an indication of how much of that acceleration is available at lower RPMs. BHP is Brake Horsepower, and refers to the method of measurement - you apply a brake torque to the engine and see what happens. It is called brake horsepower (bhp) whether it is measured at the flywheel of the engine, or at the wheels. I know back in the 60s, power was measured without any accessories on the block to bump up advertising numbers. For instance, my 2005 Volvo S60R M66 Sport. Is the engine turbocharged? Higher hp will give higher top speed and acceleration. The term "brake horsepower" comes from the device used to measure power at the engine, which held the engine at a particular rotational speed. WHP = Wheel Horsepower. It may not be wrong to say horsepower to mean wheel horsepower, namely because horsepower itself has many forms and definitions (see wiki), but most people choose to make the distinction; hp: crank/bhp, whp: horsepower as measured at wheels.
