Prior to the 1972 model year, American automakers rated and advertised their engines in brake horsepower, bhp, which was a version of brake horsepower called SAE gross horsepower because it was measured according to Society of Automotive Engineers (SAE) standards (J245 and J1995) that call for a stock test engine without accessories (such as ...
The article claims power output of 440-460 horsepower, instead of 375 as advertised. Is this SAE Net or SAE Gross? JDS2005 01:47, 3 February 2009 (UTC) The 450 horse your hearing is what the TRUE 429 Super Cobra Jet, horsepower ratings. They were considered unoffical.
At first the RAC rating was usually representative of the car's actual (brake) horsepower, but as engine design and technology progressed in the 1920s and 1930s these two figures began to diverge, with engines making much more power than their RAC ratings suggested: by 1924 the 747 cc (45.6 cu in) engine of the Austin Seven (named for its 7 hp ...
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.
It was initially rated (SAE gross) at 250 hp (186 kW) with a two-barrel carburetor (referred to as "2V" in engine designations) or 290 hp (216 kW) with a four-barrel (designated "4V"). Emissions compliance led to a compression drop in 1971, and when Ford switched to net power ratings in 1972 power ratings had fallen to 153 to 161 hp (114 to 120 ...
As is the case with all pre-1972 American passenger car engines, published horsepower and torque figures for those years were SAE "Gross," as opposed to 1972 and later SAE Net ratings (which are indicative of what actual production engines produce in their "as installed" state - with all engine accessories, full air cleaner assembly, and ...
Two 350 cid (5.7 L) V8s produced 145 hp (108 kW; 147 PS) and 155 hp (116 kW) (Horsepower losses can seem a bit exaggerated compared to earlier cars, however, their power ratings were now net as opposed to the prior gross ratings. SAE net power ratings (used since 1972) were taken from the engine crankshaft as before, but now all accessories had ...
A high-performance 327 cu in (5.4 L) variant followed, turning out as much as 375 hp (280 kW) (SAE gross power, not SAE net power or the current SAE certified power values) and raising horsepower per cubic inch to 1.15 hp (0.86 kW). From 1954 to 1974, the small-block engine was known as the "Turbo-Fire" or "High Torque" V8.
