Clio 172 cup
Not sure if this has been talked about before on the forum but this is a question that a few of you have probably heard of.
Firstly Im thinking about purchasing a pbv for the old williams, but Ive heard many people give totally different opinions about there usefulness and value for money and I suppose at the end of the day we all expect a few extra horses under the bonnet when we spend our hard earned cash on another bolt on goodie for our engine
Now I know what a pbv is (fuel pressure regulator) and what it does, but after recently talking to a mechanic, who works at our local rolling road and tuning garage , he told me that the pbv is a waste of money and you can gain exactly the same effect by putting a 20p jubilee clip on the fuel inlet pipe (not quite sure which pipe he meant whether it was the pipe going into the regulator or the one going out from that into the manifold) slightly squeezing the pipe and hence creating a greater pressure for the fuel to come out (the same effect when you squeeze the end of a hose pipe the water comes out faster!)
I know a couple of lads who have done exactly this on a 1.9 205 gti and an astra gte and they swear that it makes a difference, I didnt really beleive them at first but after being told by a proffesional rally mechanic that it works maybe there is some truth in it all!
Just wandered if any of you guys with valvers , willys or 172s have tryed or heard about this trick?
cheers
