I have been wanting to put a fuel regulator for a wail , but dont now what to chose from. I was looking at the vortech supercharger fuel regulators from vortech and wanted to now if i may use this on my car. Also wanted to now what does the ratio of these fmus stand for 6:1 / 10:1 ???

 

As far as fuel regulators go I would make your stock one functional (ultimate TBI mods), or go with the Jet unit or GM vacuum unit. Fancy regulators aren't really ever needed for our applications.

 

Could they work good ? I am getting one for free. It is a 6:1 of a turbo impreza. My buddy is giving it to me for free thats why i ask.

 

Well I don't think it will work unless you convert it to an external regulator. The TBI regulator is part of the injector pod assembly. It is unique to say the least. The cost of fabbing up an external unit would far exceed making your own adjustbale or going with an aftermarket piece.

 

the ratio is the ratio of PSI of fuel added, per PSI of boost added. i don't think 6:1 is optimum for TBI, i doubt it will even be close. IIRC tbi need more like 2:1

 

A vortech fmu is an exturnal unit. Now i under stand how it works, for every 1psi of boost if some one has a 6:1 fmu it will raise 6 psi of pressure more. Right? So if someone who is going to go turbo charged with a tbi needs a 2:1 to raise the fuel pressure 2 psi for every 1 psi of boost???? right or wrong???

 

That is correct, but look around, there are no 2:1 FMU's. There are also other problems.
