im getting a good deal on a BBK throttlebody. Is it better to get a 75mm or 70mm? i plan on supercharging my car in a couple of months. i will really appreciate your input.
Just to pick some figures out of the blue,
What if the discharge tube from the supercharger is 70mm in diameter feeding the throttle body and the intake plenium on the other side is 70mm in diameter what would you gain by the throttle body being larger?
