    Question dump valve so confused now?

    i know we have been over this again and again

    but there are two threads both with the same picture and i believe they are both saying put the one way valve in different directions?

    also some are saying use the FPR under the crossover pipe?????.

    how confusing is this and i can see why people again and again asking how to set up correctly????????

    example one:- http://coupeclub.bbfunplus.com/coupeclub-about172.html&

    example two:- http://www.m1gst.com/vb/showthread.p...ght=dump+valve

    the first saying point to the turbo and the second away from the turbo?



    can somebody put my mind to rest as still waiting to know how to set up mine as have just changed old GSI turbo to new VXR turbo but i cant have the spacer?

    also i still dont understand the workings of the oneway valve and how some people say the oneway valve gives a 90% pressure to the bailey DV and 10% to the stanard DV.?????????

    thanking you

    you can put the spacer in a vxr unit,the 1 way valve is good for noise but you will feel the difference in power and also the oe 1 is not only a dump valve its a re cerculating valve so putting the spacer in and doing the 1 way valve thing will totally confuse the ecu,the pipe you want to t into is the fuel bar press 1 which is under the cross over pipe this you should take boost gauge and baileys off its the best and accurate place to
