Re: more ghetto tbi questions - offy intake
I would think that it would still make a difference. It still has to carry the fuel/air mix from the place it was mixed (throttle body, i.e.: Howell) to the cylinders. Even in port injection, the size and shape of the intake runners have a big impact on how the engine performs. Why do you think the Corvette has such an elaborate intake runner setup when it is TPI? The size/volume/shape of the runners dictates how much air can get into the cylinder at what RPM. A dual plane (individual runner) intake will improve your low end torque at some sacrifice of high end horsepower, regardless of where or how the fuel enters the picture.
