hmm i own a superturbo and guess what? the power was superb and nothing much problem. Fuel consumption also not bad at all. OK firstly the supercharger was used to prevent lag before turbocharger start. supercharger will help you while in lower rpm and when you reach 4000 rpm tubocharger will engaged and supercharger will automatically shut down. Until now still experimenting with the system. Guess what you cab call it a vtec eater ass well
