I dont know why but the thought of hooking up two vortechs together came into my head. What would happen? The higher the boost pressure in the vacuum lines, the higher the fuel rises right? If you hook up two together and have the same springs set, then wouldnt you have twice the pressure? Dont know if anybody would need this much fuel pressure. Just a thought though.

I dont see the point of having higher fuel preassure if you can adjust it just as fine with just one. I have a vortech fmu set at 10:1 and I run pig rich.

The vortech can already control fuel over 120 psi, assuming you have the right fuel pump, which is more pressure than you really should be running on a fuel injector...The regulator itself doens't give you all your fuel pressure, it has to work along with the fuel pump too. The regulator just acts as a fuel bypass valve, sending uneeded fuel from the fuel rail back to the tank.

an sfmu doesn't give you pressure, it bleeds it off
