The Shaunster Posted June 27, 2003 Share Posted June 27, 2003 Have any of you lot got a Boost Valve ? If you do have one in your car : 1. Do you see a difference in anyway ?2. Is there a big difference in accleration ?3. Does your MPG go down ?4. Does it damage your engine in anyway ?5. Have you had any problems caused by the value ?6. Has it increased Insurance by a lot ?7. Will it increase the BHP ? Soz about all the questions but if ya can help it would be much appreciated Link to comment Share on other sites More sharing options...
simonh1 Posted June 27, 2003 Share Posted June 27, 2003 I fitted one on the advice of my tuner when I had it chipped to up the fuel pressure required when the NOS was on full 'boost'. Link to comment Share on other sites More sharing options...

RacerBoy Posted August 8, 2003 Share Posted August 8, 2003 HOW DOES THE POWER BOOST VALVE WORK? The Power Boost Valve is a high performance tuning part which replaces the original equipment valve (fitted to the vehicle). A range of models are available to suit a wide variety of European cars, which almost certainly includes yours. The benefits of the Power Boost Valve are: Original Equipment Fuel Pressure Control ValveThe electric fuel pump supplies fuel at a high pressure to the fuel rail and injectors, which is then regulated by a fuel pressure control valve. Typically, the regulator is not adjustable and is pre-set to a 3 bar maximum pressure. At idle the fuel pressure valve reduces it by 0.5 bar approximately to 2.5 bar. When accelerating quickly from standstill the fuel pressure increases at a proportional rate retaining a lean fuel mixture strength as required by the E.E.C. for new vehicles. However, the resultant effects of the standard valve produce: lethargic throttle response occasional drivability problems at slow traffic speeds intermediate performance 'flat spots' when accelerating By comparison:Power Boost Valve (replacement) Firstly, these valves have an adjustable fuel pressure, effected by the movement of an adjustment screw on the crown of the unit.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. On constant throttle and cruise conditions the valve returns to a normal regulator function.The Power Boost Valve is simple to install and in most instances basic fitting instructions are provided. These units are mechanical and are considered maintenance free. Link to comment Share on other sites More sharing options...
