My understanding is that a supercharger allows a manufacturer to use a smaller engine (squeeze adequate HP from smaller engine) and thus improve MPG. But a truck with an already oversized engine would not benefit. Yes, it would get a few more HP and the engine would possibly run a bit more relaxed, but not significantly and the supercharger would push more air into the engine and draw in more fuel, so all benefit is lost. Is this right? Or have I misunderstood the way it works?
