hi all

 

as i'm about to up the boost pressure a tad, i am advised that the stock recirc dump valves, particularly if they're old (1992 is not young anymore is it?) can leak pressure, so upping the boost can simply make matters worse.

 

and as this is possibly the only time when aftermarket bov's will be of advantage, ive started to look around.

 

i came across the Z1 RFL's thanks to another thread, and they seem incredible good value, but has anyone got any other experiences of them, i.e does it screw up the idle as some do, any issue with the running due to the ecu not seeing the air that would normally be in the system with recirc's in, etc etc

 

cheers

ps - if they're just crap, say so, but advise on exactly what would be good instead would be advantageous!

Its crap, dont buy them!

You can find exactly the same bovs on Ebay..and theire not good.

Go for the HKS SSQV if you dont want idle problems ;)

I bought some cheap ebay ones ages ago, then decided to go without. I eventually bought some apexi ones and come highly recommended from me, no idle issues at all.

The ebay ones where totally crap in comparison.

I had apexi ones on my old zed, which i bought from Danny@DTA. Very good, no idleing problems, fitted very easily in the stock postion, and theyre not too offensive. But the HKS ones also sound very nice.

I have the Apexi's and theyre great. No probs at all and they go in place of the re circs too!!!!!

thanks guys

 

so who's best supplier for the apexi?

 

also, once a common fit to just about anything turbo'd, what about the bailey dv26's?

 

and finally, what's the advantage of the hks and hard pipe kit over replacing the re-circs with a better valve in the same position?

 

cheers

The closer the BOV is to the inlet manifold the better IIRC, so BOV's mounted on the outer pipes aren't as good as the Apexi's that replace the re-circs. There is a hard pipe kit that goes on the inner inlet pipes which i guess is the best ?
