    Hey Guys,

    Whats your thoughts ona dump valve? I think they sound awesome and seems to me to be purely cosmetic. However i was advised by a garage in aberdeen not to fit one as it decreases the performance......

    Up until a point, they offer no real significant benefit other than the sound although it wont decrease performance.

    Although my car is a Jap turbo i had always led to believe that dump valve was better for a turbo car in this case the pressure exceeds the preset spring pressure in the dump valve and the excess pressure is bled off to atmosphere rather than back in the turbo again.

    It could possibly decrease the performance, but every car is different, id say its one of these things you need to try and find out though :)


    Or what sweeney has linked up




    Ps. nothing to do with me being JC in this post!

    Might be a bit strange with the Auto tranny though.

    i'm not sure if it'll make any difference being an auto, guess the proof will be in the pudding.
