Just fitted fmic and Induction kit to UK MY99 Took it for a drive and it was making some funny swooshing and grating like noise out of the air filter and wasnt running right at all
so i put the OE dump valve back on and it runs spot on with loads of power, the Baileys dump valve is only 3 months old and its a pile of ****e

 

Wry smile.

You may well be able to adjust the Bailey valve to integrate it with your new setup, but as you've found, the standard item works so well that there's really not a lot of point wasting your time piddling about with the aftermarket one.

Still, on the plus side, you'll probably find someone willing to buy it.

 

after fitting a fmic its normal to get the loud chattering through the induction filter but sounds a bit iffy if you have not heard it before lol this is normal

 

Running like a bag of hammers is not normal, Glad he seen sense and got rid

 

i ment the sound coming from the air filter!!! i was not talking about the bailey valve!!

 

Ohh, TBH as much as i hate dump valves I think Baileys are probably the poorest out of the bunch

 

and i would agree with that also, they aint good for the money

 

sort of answers the question really , do like i did ebay it

 

Another one for OEM dump valve mate..... Went from OEM to HKS SSQV for a year or so and reverted back to OEM.
