This dyno sheet shows both pulls on Chad's supercharged Mustang. The car made almost exactly the same horsepower and torque readings as before the intake manifold exchange. Because the engine is running at 14 pounds of boost we weren't too surprised that there was little improvement as the result of a manifold swap. On this engine combination we would anticipate the power ratings to closely follow the boost level and inlet temperatures and design improvement nuances in the intake manifold that would shine under normally aspirated circumstances are overshadowed by the seriously compressed air. The EFI Hurricane intake is capable of supporting up to 7,500 rpm and with the peak power coming at 6,000 rpm it seems clear that the intake manifold was not the limiting factor on the supercharged application.
