Why is that? I would think with a plenumless design there would be no ristriction on the air flow coming into the engine. If this is true then an ITB setup would make more power due to its inherent ability to supply each cylinder with the proper amount of air required to make the most power and bring up the VE of the engine given that all fuel metering and requirements are met. I may have my facts wrong. If so please explain your theory. I would agree that the OBX ITB setup is not the most optimal setup to purchase but I have seen people take them and make decent power numbers. My inquiry is over the choice of OBX to place the fuel injector in front of the throttle butterflies when almost all other ITB manufacturers place their fuel injectors after. I find this odd due to the fact that if the fuel hits the throttle plate it will liquidize and cause idle problems and poor fuel consumption. I can understand the setup with WOT but you don't drive the car this way all the time. So my main question really would be how would this work on a car that is at idle or at low throttle?
