BLOW OFF VALVES or DIVERTER VALVES?

**BsA4** · 03-28-2005 09:23 PM

I would like to know which is better for a 2004 Audi A4 the "Turbo XS Type S (BOV)" or the "Bailey Motorsport Alloy Diverter Valve"? Will I be able to hear the "Woosh" sounds outside my car from the both of these? Will I see any horsepower or TorQ. gains? Thanks for the help....

BOV's generally make the Audi run like crap because the MAF calibration assumes that 100% of the air will be diverted back in the air intake side. If not, the engine will run rich. You could get a hybrid and set 80% to intake and 20% to atmosphere, or buy one of these....

whoosh here

More info if you search the archives...

A lot of people with the B6 1.8T run a Forge 007 Diverter Valve...do a search to see everyones opinions on that subject.

Between the 2... Baileys is better for you car but wont have to much of that Woosh sound.... if you get a DV and an intake you can improve the sound a little.... as far as HP and Torque you wont get much....

i talked to jack yesterday at ecs tuning and he said that the hks ssbv would work fine on the car and not mess anything up as far as sensors and such. So im going to order one when they come in from back order. does anybody else have one any opinions???
