Turbochargers vs Superchargers: The Great Debate

TURBOCHARGER VS SUPERCHARGER THE GREAT DEBATE TURBOCHARGER Significant increase in Boost threshold horsepower Turbo lag Higher Efficiency Turbos get very hot and can tap into the engine's oil supply Turbos produce much more power relative to their size Generally quieter than superchargers because the turbo's turbine is in the exhaust The boost threshold can provide an instant surge in Better fuel 50 economy 40 power, leading to instability 30 20 10 Turbochargers improve fuel economy by as much as 20 TO 40% 2019 The turbocharger market is expected to grow even faster over the next few years with 43% OF NEW VEHICLES, expected to be turbocharged by 2019 Despite being considered an "older" technology, the supercharger was invented just a few years before the turbocharger SUPERCHARGER Often known as a "blower" because the original design was developed to blow fresh air down No lag mineshafts. 111 771 Increased horsepower Superchargers require engine power and are therefore less efficient Low RPM boost than turbochargers Fitted to almost everything, including planes, trains, boats, and even lawnmowers! Superchargers are a cost effective way to increase horsepower All forced induction systems (including turbos) require the engine internals to be exposed to higher temperatures and pressures 1912 1885 HISTORY 1925 1938 Dr. Alfred J. Büchi Gottlieb Daimler and Rudolf Diesel tested the effectiveness of developed the first exhaust-driven increasing the power output and reducing the fuel consumption of their engines using pre-compressed combustion air. supercharger. and proposed the first prototype of a turbocharged diesel engine. Büchi demonstrated the The Swiss Machine Works advantages of exhaust gas turbocharging by achieving a power increase of more Saurer built the first turbocharged truck engine. 1973 than 40 % 1994 2014 1996 The Toyota Supra Turbo becomes the BMW led the resurgence of the automobile turbo with the 2002 Turbo, with Porsche following with the 911 Turbo, introduced at the 1974 Paris Motor Show. quickest car the company has ever sold in North America. Hardcore tuners help make the Supra Turbo legendary. Turbo manufacturer Garret by Honeywell projects 49 million turbocharged vehicle sales per year The KO3-003 Turbo is installed in the VW Jetta in addition to many more light by 2019. car passenger vehicles. This turbo goes on to become the most widely installed turbo in history. BuyAutoParts.com sells more than 5,000 turbos this year. THE FUTURE PROMISE OF Turbochargers are increasing at a dramatically faster rate than industry experts had predicted, leaving superchargers in the Turbochargers also help reduce harmful exhaust emissions, in addition to providing improved fuel efficiency. TURBO CHARGERS DVST & THE DEATH OF THE SUPERCHARGER Turbocharged engines offer a "no compromise solution" for automakers that need to Manufacturers are combining turbochargers with direct fuel meet increasingly strict fuel economy and emission standards, while meeting customer demand for better-performing vehicles. injection technology to allow them to offer ВАР smaller gasoline engines, which saves fuel without BUYAUTOPARTS sacrificing power.
