just a quick question on this.
why is it that on the racing beat headers they encorage to get teh headers/presilencer combo only if your fc is or is gonna be a carbed ( carburation) fc. Is this for smog purposes only? or are they any downsides. I know most people in thr forum run with the rb headers yet they all use the fuel injected system.
thanx and sorry for not using search

The two together give more horsepower, however I'm running just the header and making much more horsepower then stock. Maybe just a marketing thing? Give them a call they are really nice to talk to and very helpful.

well i dont doubt the horsepower increase i just want to know why they would write such a thing. I mean converting a fuel inkected fc to a carbed one is at least 2k

Their kit costs 750-850, and it comes with some options aside from that, All said and done you can't be looking at more then 1000-1100.

The question is, why would you want to? I had a carb in my 83 FB, and I'll never drive another car with one again. Unless it was a drag car or something and not a daily driver..

The header was probably designed with a carb'd intake. It will make more power with their carb over the stock EFI, but the header will still make a noticable increase without the carb.

Do not turn this into a carb vs. EFI debate. That has been rehashed here too many times.

I just checked the Racing Beat website and could not find any reference to requiring a carb conversion.

quote from racing beat:
___________________________________________
For optimum performance gains for this application, we recommend that a header be used on an engine configured with a carburetor intake system. For this reason, we suggest another suitable configuration for use on a fuel-injected engine is the Racing Beat Catalytic Converter Replacement Pipe with Presilencer combo

It doesnt say you are required too it says for optimum performance gains.

Congrats on ur car aaron!

This link says that for optimal gains, use a carb'd intake. Its not required at all.

Hans- Does it look like my Sport has a carb? no I have a Road Race header in place. You don't need to use a carb for the header. Besides man your broke. And your always complaining about your car being broken so why mod it anymore? Your only going to bitch more.
