Electric supercharger promises instant power boost

Now here’s an idea that begs the question as to why someone hasn't thought of it before. Controlled Power Technologies (CPT) has come up with a clever technical solution for the problem of ‘downsizing’ engines without compromising driveability and performance – the electrical supercharger. The company’s low-cost, production-ready, Variable Torque Enhancement System (VTES) employs an electrically-driven supercharger to significantly improve low speed torque response for naturally-aspirated or turbocharged gasoline and diesel engines. Unlike traditional mechanically-driven superchargers and exhaust-driven turbochargers, it doesn't suck power all the time because it is only engaged when needed, and delivers an immediate boost within 350 milliseconds. Most significantly, CPT claims the VTES can be implemented on current vehicles, using existing 12 volt electrical architecture, and when used in series with a turbocharger, the 2kW of electrical power translates into 20kW at the crankshaft.
