Supercharger biggest disadvantage

Aircraft engines and automotive mechanical supercharger using the same. They get power directly from the engine , the use of compressed air into the combustion chamber of the compressor . The figure shows the basic mechanical supercharger installation on the aircraft.(renault turbo)

Volkswagen AG (Volkswagen) recently launched a Twincharger engine for the Golf GT car. Twincharger combines a supercharger and turbocharger. When the engine speed is low , the mechanical supercharger air into the cylinder will be to enhance its low-end torque . When the engine speed is high , a sufficient number in the exhaust gas turbocharger into the air will be pushed to increase the performance of high-end torque . GT is only sold in Europe , it is the speed in 7.9 seconds from 0 to 99.8 km . Its speed can be increased to 218.9 km per hour , while still maintaining 39MPG. The first time you use the supercharger on the plane in WWII . The most famous example is the Supermarine Spitfire, which is the aircraft used by the RAF , the mechanical supercharger installed on the Rolls-Royce " Maureen " engines.(renault turbo for sale)

Supercharger biggest disadvantage is: As driven by the crankshaft, they must be part of the engine horsepower loss. This is also one of the characteristics of the mechanical supercharger supercharger will take a 20% engine power. However, due to mechanical supercharger can increase horsepower by 46% , so most people think that the deal is worth it.
Since the supercharger will increase the burden on the engine, the engine must be strengthened in order to withstand the extra pressure and more explosive . Most manufacturers in the design of an engine with a supercharger when using heavy-duty components are dedicated to improve the life of the engine . This will also raise the price of the car . Supercharger maintenance cost is also high, while many manufacturers recommend using high-grade gasoline .
Despite these shortcomings , the mechanical supercharger is still one of the most cost-effective method to enhance horsepower . Supercharger can be increased by 50 % -100 % of the power to make the car more suitable for games, driving heavy transport or simply increasing irritation .(ignition coils)
