Any non-convertion turbo guys running FMU

[punkak2]

i got a 98 gst with evo3 turbo and a buddy of mine gave me a Vortech FMU. I did a search on it and could only find 2gnt guys running turbos using this product. I was just wondering if any one has this on there cars and how it is working out for them.....

You already have a rising rate fuel pressure regulator... so it wont do any good to use it.

If you dont have a pump, you can probably trade it or sell it and the pump will do you more good. You would need a fpr not the vortech since the turbo stock fpr is already rising rate. The vortech is used to add fuel on a ratio thats preset by seals inside the fmu. I am not sure if this is how it works, but I was told a 12:1 seal should be good for up to 12 psi. If you are considering using some fuel management, and you are already turbo, youshould be past the 12 psi mark.

Yes, turbocharged cars need rising rate fpr's to keep fuel pressure "constant" as boost increases. That is why the n/t guys use these kits. Our cars have no need for them.
