Default Re: Which is faster carb or Fuel injection?

This is just our experience, but like has been said in previous post, if everything is apples to apples, their is no noticeable difference. Tuneability and the ability to squeeze out every little hundredth is a big plus for the F.I. The comparison on fuel readings off the Egts are not even close, and we have a pretty well tuned carb. You can get the F.I to somewhat flat line the target fuel curve, and you just are not going to do that with a carb.
We broke in, then dynoed our engine with a carb, and then a box manifold/F.I set-up, and lost 13 horsepower with the F.I. .. The carb was a 750 Q-Jet, but our combo uses the stock 48 mm tuned port (L-98) F.I throttle body, and those little bores suffocate a 350. I am guessing on a 305, the numbers would be closer as not as much air would be needed for good power.
