    i have fitted a forge splitR dump valve to my audi a4 1.8t but it does not make much noise, but according to the carbonio CAI it will increase the noise HOW ?
    i thought you would have to increase the boost pressure ( i.e remap) to make the dump valve louder ?

    HOW DOES A CARBONIO CAI INCREASE THE DUMP VALVE WHOOOSH ? :confused:

    well sounds like they are playing on the idea that carbonio will have more air flow than the standard filter so there will be more hissing out the dump valve, but have yet to know of real world this happening.

    All cone filters ive tried on my golf make the dump valve sound louder,i think the airbox acts as sounproofing on the intake.When its gone you can hear the whoosh through the filter.
