Which is faster carb or Fuel injection?

If the comparison was made with identical manifolds and the same total area throttle body/throttle blades, and fuel curves both optimized to whatever extent possible, I'll argue that the FI has superior atomization, and should make a little more power at every increment.[/QUOTE]

Let's take an look at a ringer in the Mopar DragPak engine with the tall single plane and throttle body on top. Easily replaced with a carb. If the throttle body was flowed, a really good Holley was assembled to match, have a feeling that there would be little to nothing.

Don't think there is any way to compare EFI to Carb in a stocker apples to apples. If you look at the potential of the combination with it's HP rating then you have something to study. Not being a dedicated student it appears to be a new car or a slow car.
