With or without the AHFS?

Re: Which is faster carb or Fuel injection?
 

Bill: I was comparing two motors, two different cars same HP and basically same specs with the only difference being carb vs EFI.

The FI cars leave harder in lower HP cars then the carb cars, I am not sure in higher HP cars because they all leave hard.

Looking at slower cars in my older age...

Joe Didn't you go a 10:92 in H/SA at Atco this year? How fast do you want to go? I don't see many older Fi cars going 1:23 under. You just have to much time on your hands. Barry

That's tellin 'em Spanky.

Brother Parker, you taught me everything I know.... but not everything you know about going fast. Your vette is still sleeping, when are you going to wake that thing up????

I lost something at Lebanon Valley and can't find it, thinking keeps me young.

Joe where have you been hiding. You going to Indy. We are thinking about it. If your not going I may run H. Barry

Joe, I know what you meant...

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.

With my last engine we did a test to see if there was a big problem with my EFI setup and took off the tune port and put on a 350 manifold, not the best but good and a dyno Q-Jet and picked up 20 HP. Nothing else changed.

Joe, on Bryan's 305 the carbureted combo made 20 more horsepower than the F.I. and made power at a higher rpm. The F.I. combo makes more torque and has a flatter torque curve. run at the same weight the carb is faster.
