FUTURE OF SUPERCHARGING?

Alexander Hohenegger reckons that his new ‘supercharger’ has much in common with the theory of a two-stroke exhaust. It contains no moving parts, instead relying on a membrane that naturally vibrates in time with the engine. It’s plastic and costs four times less than a turbo. Alexander claims a 15% increase to either bhp or fuel economy when tested. Dubious? Us to.
