FSE Power boost valves


The Power Boost Valve is a high performance tuning part which replaces the original equipment valve (fitted to the vehicle).

New Power Boost Valves are pre-set with a maximum fuel pressure of 2.5, 3.0 or 3.5 bar, depending on the vehicle in question, and similarly (to the original valve) the fuel pressure is reduced by 0.5 bar approximately at idle. There the similarities end.
On acceleration from standstill the Power Boost Valve fuel pressure will increase at 1.7 times the standard rate. This will produce a healthy, strong fuel mixture strength which will instantly improve the drivability of your vehicle, providing:-

  • instant throttle response
  • removal of performance flat spots
  • faster acceleration
  • extra engine performance

The regulator enhances engine performance on acceleration by enriching the mixture strength.
