Engine power is the power that an engine can develop. It can be expressed in power units, most commonly kilowatt, metric horsepower (often abbreviated PS), or horsepower.In terms of internal combustion engines, the engine power usually describes the rated power, which is a power output that the engine can maintain over a long period of time according to a certain testing method, for example ...
Citing measurements made at the 1925 Iowa State Fair, they reported that the peak power over a few seconds has been measured to be as high as 14.88 hp (11.10 kW) [11] and also observed that for sustained activity, a work rate of about 1 hp (0.75 kW) per horse is consistent with agricultural advice from both the 19th and 20th centuries and also ...
Power-to-weight is often quoted by manufacturers at the peak value, but the actual value may vary in use and variations will affect performance. The inverse of power-to-weight, weight-to-power ratio (power loading) is a calculation commonly applied to aircraft, cars, and vehicles in general, to enable the comparison of one vehicle's performance ...

The Toyota GR engine family is a gasoline, open-deck, piston V6 engine series. The GR series has a 60° die-cast aluminium block and aluminium DOHC cylinder heads.This engine series also features 4 valves per cylinder, forged steel connecting rods and crankshaft, one-piece cast camshafts, a timing chain, [1] and a cast aluminium lower intake manifold.
In 2011, Super Chevy Magazine conducted a chassis dynamometer test of a well documented, production-line, stock but well-tuned L-72 "COPO" Camaro, and recorded a peak 287 hp (214 kW) at the rear wheels, demonstrating the substantial difference between 1960s-era SAE "gross" horsepower ratings and horsepower at the wheels on a chassis dynamometer.
The difference between this engine and a RB26DETT is that the engine is bored and stroked 87 mm × 77.7 mm (3.43 in × 3.06 in) which results in 2,770 cc (2.8 L). The engine produces 450 PS (444 hp; 331 kW) at 6800 rpm and 48 kg⋅m (471 N⋅m; 347 lbf⋅ft) at 4400 rpm.
The torque curve was revised, with peak torque coming at a lower engine speed in the FA24D, and without the significant torque decrease between 3,000 and 5,000 RPM exhibited by the FA20D, which resulted from tuning that engine for fuel economy. [20] In addition, an oil cooler has been added to the engine. [21]
