Brake horsepower per cubic centimeter or (bhp/cc) is a figure of merit that is used to indicate the 'state of tune' of an internal combustion engine. It is defined as the ratio of the engine's net power output to its displacement, the internal size. Power is measured at its rated speed and full throttle.
This conversion resulted in a power increase from 103 kW (140 PS; 138 bhp) to 110 kW (150 PS; 148 bhp) of the standard 3.0 version, and 117 kW (159 PS; 157 bhp) for the fuel injection version, plus a useful boost to fuel economy. Only about 1,600 of the EFI variants were produced during 1992 and 1993.
Brake horsepower (bhp) is the power measured using a brake type (load) dynamometer at a specified location, such as the crankshaft, output shaft of the transmission, rear axle or rear wheels. [ 30 ] In Europe, the DIN 70020 standard tests the engine fitted with all ancillaries and the exhaust system as used in the car.
A typical turbocharged V8 diesel engine might have an engine power of 250 kW (340 hp) and a mass of 380 kg (840 lb), [1] giving it a power-to-weight ratio of 0.65 kW/kg (0.40 hp/lb). Examples of high power-to-weight ratios can often be found in turbines.
Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article. Exceptions are made if the unit is commonly known by another name (for example, 1 micron = 10 −6 metre).
Brake-specific fuel consumption (BSFC) is a measure of the fuel efficiency of any prime mover that burns fuel and produces rotational, or shaft power. It is typically used for comparing the efficiency of internal combustion engines with a shaft output.
The first M was a 2.0 L (1,988 cc) version produced from 1965 through 1988. It was a 2-valve SOHC engine. Cylinder bore and stroke was square at 75 mm (2.95 in). Output was 110–115 PS (108–113 bhp; 81–85 kW) at 5,200 to 5600 rpm, depending on specifications and model year.
The conversions came with a full Rover warranty, and could initially be fitted by any franchised Rover dealer.
