Message: <blockquote data-quote="jswong" data-source="post: 675170" data-attributes="member: 8004">Oh no, Protonevo's not gonna get his share of credit once the idea becomes marketable!By the way, there were commercial implementations of "electric superchargers" using powerful motors that spin at over 50,000 rpm.. not something that you're likely to get from Pasar Road or any old machinery, that's for sure.But these ideas never took off. Why? Because electric motors that spin at such high rates are prone to failure. In other words, the device was unreliable compared to mechanical means like supercharging and turbocharging.Come on la, if it's viable, the car manufacturers would have used it. Instead, they'd rather go for light pressure turbos and superchargers. Why? Why do they still prefer it even though it's more troublesome in every sense - from the maintenance of the units, to the way it needs to be mounted, etc.?If an electric supercharger was REALLY viable, wouldn't Volvo and Audi be interested in it, since they already use light pressure turbos across their product range?Not to say that you won't get any gains from it. It may give you some effect, but in the long run, the unit may not be reliable enough for continuous usage.</blockquote>
