If the car is tuned properly there is no doubt that 48 IDAs produce more power than a four barrel; you have a venturi spraying cool emulsified fuel right into the intake port from about two inches away. For all practical purposes you have a fuel injection system. I wondered if it would make a big difference too, so I checked. Using the same chassis dyno before and after, I gained 44 HP.
