can someone tell me the differences in the bailey and bosch diverter valves? besides the price, what are the differences? the bosch are going for 44 each where as the baileys are going for 160 each

 

Bosh OEM plastic
others, rebuildable & tunable, made of metal.

 

Ummm - another newbie question. I'm hearing a whoshing sound under acceleration and I've read its probably the bi-valves. Is this the same as diverter valves or something different?

 

same thing

 

Are you sure it's not the turbo's spooling up? You should not hear the DV's at all. If you do hear a noise like it, then you have a boost leak some where.

 

I have that sound under acceleration and have full boost and no boost leak (pressure tested). It's normal.

 

Hmm - I just don't seem to remember that sound when I got the car a couple months ago. But I love this car so much I feel like a parent whose kid coughs and are sure they're dying of something. Sometimes I feel it's down on boost other times not. I'm thinking maybe I just don't know how to drive the car properly to build boost when I want it. I just ordered some Hyperboost DV's - Rich at Stratmosphere gave me the same price as the forges. I let you know if it affects anything. Thanks everyone as always for the advice.
