FSE, Power Boost Regulators - garbage or useful?

Low Pressure pump from tank to swirl pot, High pressure from swirl pot to Fuel rail which then return via standard fuel regulator back to the tank..

That is not what I meant with my question. I wanted to know what fuel system you had..flapper, hotwire, GEMS, Motronic..

Engine is standard Rover 4.3 but now has supercharger fitted and now needs to be remapped..

There is no standard 4.3..can you reconfirm?

With the supercharger came this device >> http://neptune.spacebears.com/cars/stories/scfmu.html
but I have not fitted it yet, do you think I should fit this in place of the standard regulator.

I have seen one sort of like this before. Unlike the FSE, which allows you to adjust the fuel pressure and gives you preset fueling increase in high demand situations, this device comes with a preset fuel pressure but allows you to adjust the fueling increase in demand..both when and how much.

That would seem to be a benefici compliment to a supercharger. However, you want to know what the base pressure is set to and whether a stock unit might do as well.

You can do the first that by hooking it in and testing the pressure, OR researching what is th base pressure for a 1995 Mustang GT. The rest would be trial and error.

Hi Racer,

Its hotwire and the engine is from a 4.3 TVR Griff.

With the stuff above, we have figured out why Mark (Adams) advised you the FSE would not be necessary. He was absolutely right..but, traditionally he is not one to spend his time on explanations.
