Applying that to electronics, a 12-volt battery will barely be capable of providing the energy needed to perform anywhere near the same capabilities of an engine’s crank. This motor is powered by an attachment to the car’s battery which brings up an inherent problem with electric supercharging.Ĭompressing air takes a whole load of energy around 6-7bhp for every psi of boost is sapped from an engine to drive a mechanical supercharger. This allows for the electric motor to spin the fan at a rate in proportion to the amount of throttle being applied, simulating the belt-driven action of a conventional mechanical supercharger. The electronics come in the shape of an electric motor connected to the throttle either at the throttle body in the engine bay or at the throttle pedal. These ‘superchargers’ are in fact only bilge pumps, designed to help pump unwanted water from the deck of a small boat. You can find plenty of these contraptions on the Internet but it is essentially a big scam. Attached directly to the inlet manifold, the cylindrical component acts basically as a desk fan, sucking air into the intake and then forcing it into the cylinders. The first is more of a fan than specifically a supercharger. There are two types of electric supercharger. Although Formula One has come along and used electric motors for turbocharging purposes, electric superchargers have also been floating around the internet as a possible modification in the last few years. Almost seen as a ‘bolt on’ application, some of the greatest powertrains ever made have been supercharged, be it Jaguar’s V8, the 5.4-litre engine from the Mustang GT500 or the 638bhp motor from the Corvette ZR1. That high-pitched shriek from the belt-driven mesh as it compresses air into the cylinders is one of our most loved sounds as petrolheads. If you want to know more about why Duryea e-superchargers work, read more about our innovative 12VDC motor below.There’s nothing quite like a supercharger whine. We feel high-quality electric superchargers are ready to take the aftermarket by storm because they offer so many easily achievable benefits – boosting low end torque, eliminating turbo lag, and they can even improve emissions and fuel economy, if properly tuned. The result is an abundance of ineffective, albeit cheap, devices on the internet.Įlectric supercharging is a proven technology it’s been long utilized in Formula 1 and racing, and is now being adopted by major automotive manufacturers that are launching mild hybrid performance vehicles. We at Duryea believe the reason e-superchargers have a mixed reputation is because too many companies have built them with motors not suited to the application. Special high-current, low-resistance brushless DC motors and proprietary integrated electronics, such as those manufactured by Duryea Technologies, are necessary. Why? For an electric supercharger to work effectively, it must have the right motor and power electronics.
The result is more power and a cleaner burn from your fuel.ĭuryea electric superchargers work. Its electronic controls increase airflow at critical times to allow for complete combustion. An electric supercharger's output is independent of the engine. Most particulate emissions emitted by an engine running at part load (idling, decelerating or accelerating) occur when there is insufficient oxygen to combust fuel completely. This highly efficient system provides boost instantaneously, well before the engine is up to speed, offering superior performance without the lag associated with turbo chargers. An alternator, maintains this stored energy. Although there is a net gain in horsepower, belts are a parasitic drag, siphoning off some energy from the engine to drive the supercharger.Īn electric supercharger, also known as an e-supercharger, is driven by an electric motor, which is powered by stored energy. Therefore, it can lag until the engine reaches a sufficient speed. The additional oxygen enables complete fuel combustion, which in turn increases boost and decreases particulate emissions.Ī belt-driven supercharger's performance depends on the speed of the engine. All superchargers, both belt-driven and electric, compress air and increase the amount of air delivered to an engine.
