Re: Which is faster carb or Fuel injection?
 

I guess the question is are there any Stock eliminator cars that have the option to go to one or the other? You are stuck with what came in the car in any given year, if there were any that came with both available it would have been rare.

Re: Which is faster carb or Fuel injection?
 

X2 I am hoping someone starts the thread about the difference between FI Headers and Carb Headers. Always learn alot here.

Re: Which is faster carb or Fuel injection?
 

1985 Camero came with both carb-263 hp or tuned port F.I.-258 hp. These are the NHRA factored ratings. Engine specs are the same excecpt for the induction.

LEE, is the carb version what is called the big cam? If so don't think the TPI can run with it. Please correct me if I'm wrong.
Both can run at the same minimum weight, same cam, same piston and chamber, head castings are different.

Re: Which is faster carb or Fuel injection?
 

Check again Frank , 305-175 flattop-big cam carb and 305-215 TPI use all the same #'s and cc's . same cam ,416 head etc.

I could have Memory failure, but seems like one or all three of those '85 FI intakes are not so good.

Re: Which is faster carb or Fuel injection?
 

Lee, I stand corrected.
Both engines are the same but for the top.

Re: Which is faster carb or Fuel injection?
 

I've seen batch fire and sequential mentioned how bout timed injection? Having the ability to dictate when the injector pulses would seem to be of benefit. Not sure how many systems offer this or how much time has been spent testing it.Spraying fuel into an active air column would seem at least in theory to have some potential gains.

Re: Which is faster carb or Fuel injection?
 

Joe, you can time the injector pulse in the FAST XFI, and likely the other race systems as well.

Re: Which is faster carb or Fuel injection?
 

Yes Ed, wasn't sure about others, my ECU-882 has that ability however I've yet to do any serious testing using it. Would be interesting to hear from someone that has. At higher engine speeds I'm imagining a serious amount of feul vapor being flying around in my manifold....is it a detriment or a help...I'm not sure.I've even wondered if my manifold design since it was made for a carb is a hinderence guess time will tell. BTW my car has ran as fast if not slightly faster with the EFI versus the carb, though again it may be contributed to the manifold and head design more than the actual delivery system....sure can't beat the EFI throttle response though.
