How to Fit a Power Boost Valve

[markh72]

I have a Clio 16v 1.2 and im trying to fit a Power Boost Valve, the instructions dont make any sense?, has anybody fitted one of these ? got any pictures



cheers

whered u get that from? no idea how tofit it...b interested in knowing performance gains.

Stand about 2-2.5m away from car open bonnet and throw.

Now now Tom, when fitted and set up correctly, they dont do too much damage!

its the most pointless piece of sh*t i have ever seen.

works really well as a beyblade tho

I know what you mean fella, but for turbo cars with larger capacity injectors they have their benefits!

 

[Clart]

hes only jealous cos he aint got one

 

[markh72]

hmmmm doesnt help me much though chaps !!! i know i wont get any bhp increases from it, but i believe they do give better throttle response

 

[Tom]

Doubtful. give it a go. does it come with instructions?

 

[crono33]

what is it and what it does?

ok is a settable fuel pressure valve.
well what is stated in that site is a load of bull. the standard bosch fuel prex valve fitted to my motorbike has such fast response that when measuring the pressure of the fuel rail the needle of the pressure gauge oscillates at the same frequency of the vacuum pulses present in the manifold

therefore forget about it

 

[jimbo]

the FSE is a rising rate regular, e.g. it is dependant upon manifold vacuum as to how far it opens. this is why its better on turbo applications

it will work, why exactly youd want one i dont know, its £90 i could spend more wisely for you on your car lol

dont expect the world from it when youre running stdish engine (which i guess you are?)

and crono...you must have good eyes to see the pressure osscilating 50-100 times a second, and be able to compare it to the manifold vacuum too!! hehe

unless you used some funky electronics to show little graph traces

 

[crono33]

hehe right in fact the needle was a blur. i had to shortcut the fuel pump relay so it was always on and checked that way.

anyway, the duke idles at 1000rpm more or less and at 1 inlet phase per turn, with a little patience u can spot the needle ;-)

i can see that i may have wasted £98 then !!, i currently have a K&N induction kit installed and a Magnex 7" oval SS exhaust full system, from the CAT onwards. trying to reduce the weight also, as the standard 1.2 extreme is very heavy !. i was hoping the boost valve would add a little Va Va Voom !! haa haa haa !!

 

[DeanRSi]

i didnt think they fitted the new clios?

 

[markh72]

not sure what you mean ?

 

[jimbo]

well it wont do any harm, and it will probably make the throttle a little more responsive

if you ever find out how to fit it....whack it on and see, nowt to lose

 

[JAY172]

you cant fit a boost valve to a 1.2 16v because the standard regulator valve is part of the sender unit in the fuel tank and there is no fuel return from the injection rail.

just to point out that turbo engines dont have an inlet vacuum when off boost.

ive said it before, if ur gonna get 1 of these, have a look in DT motorsport catalogue. they sell an "adjustable fuel pressure regulator" for 40 odd quid. its EXACTLY the same!!!!! probably made by the same people, just not aimed at a boy-racer market and so not called "POWER BOOST valve"

part # AIR001

(page 198)

The difference is the diaphram, on the PBV its larger and more responsive and the rate of increase, unlike std producitonones (including your DT catalogue one), us higher.

Its also boost aware and can increase your baselines pressure on boost, slowing down the rate of duty you use making mapping easier. And since its adj, it doesnt matter that turbos dont have a vacuum when off boost.

and like Jay said, a no no on the 1.2.
