V8 Engine

A V8 engine is a V engine with eight cylinders mounted on the crankcase in two banks of four cylinders, in most cases set at a right angle to each other but sometimes at a narrower angle, with all eight pistons driving a common crankshaft.
In its simplest form, it is basically two straight-4 engines sharing a common crankshaft. However, this simple configuration, with a single-plane crankshaft, has the same secondary dynamic imbalance problems as two straight-4s, resulting in vibrations in large engine displacements. As a result, since the 1920s most V8s have used the somewhat more complex crossplane crankshaft with heavy counterweights to eliminate the vibrations. This results in an engine which is smoother than a V6, while being considerably less expensive than a V12 engine. Most racing V8s continue to use the single plane crankshaft because it allows faster acceleration and more efficient exhaust system designs

Arguably, Ferrari had their first contact with V8 power with the "inherited" Lancia D50s in 1955. Ferrari adopted the V8 configuration for themselves for racing in 1962 with the 268 SP. The first V8-powered Ferrari road car was 1974's 308 GT4, with the familiar 308 GTB following closely behind. The company continued to use this Dino V8 engine ever since with the 328, 348, and successors. Ferrari's smallest V8 (and indeed, the smallest ever) was the 2.0 L (1990 cc) unit found in the 1975 208 GT4. The company produced a slightly larger 2.0 L V8 in the 208 GTB and the 2.9 L Ferrari F40 of the 1980s. This was a turbocharged engine to reduce the road tax of the car in Italy. Automobiles with engines displacing more than 2.0 Litre were subject to a much higher tax rate. Five-valve-per-cylinder versions of Ferrari's 3.5 L and 3.6 L V8s were found in the Ferrari F355 and Ferrari 360. The old Dino V8 was retired for 2004 with the introduction of a 4.3 L V8, based on the originally Ferrari designed Maserati 4.2 V8, in the F430 and the California. And F430's successor, 458 Italia, with 4.5 V8.

Bentley engine

The Rolls-Royce and Bentley V8 still used in modern Bentleys was designed from 1952 and entered production in 1959 in the Rolls Royce Silver Cloud and Bentley S2. Following then current design practice, it featured overhead valves (OHV), a central camshaft and wedge-shaped combustion chambers. It was designed by the Rolls-Royce and Bentley Motors engineering team, led by Jack Phillips. Some of its features were inspired by the Rolls-Royce Merlin aircraft engine, including the aluminium block with wet liners, gear-driven camshaft, (initially) outboard spark-plugs and porting. Early versions were of 6.25 L (381 cu in) displacement, growing to 6.75 L (412 cu in) in the 1970s. Turbocharging in various Bentley models beginning in the 1980s led to the resurgence of the Bentley marque as the power outputs of the engine were increased in several steps to the current 500 bhp (370 kW) and 1,000 N·m (740 ft·lbf) in the 2007 model-year Bentley Arnage, while meeting all emission standards. The Bentley V8 has thus increased power and torque by more than 150% in its life. It is the highest torque V8 used in a production car. In 2007, the final components that could be traced back to the 1959 engine were replaced.
In 1936, the Standard Motor Company introduced its 'Flying Twenty V-Eight' model featuring a 2.7 L flathead V8 developing 20 RAC horsepower. It was the flagship model of the company's 'Flying Standard' range but proved unpopular as it offered little performance improvement over the normal 'Flying Twenty' model (which used a straight-6 engine) whilst costing much more to buy and suffering higher fuel consumption. The Twenty V-Eight was on sale only for the 1936 model year and fewer than 400 were sold
