[QUOTE="Hotrodtractor, post: 90890, member: 25"] I need to come back and elaborate a little bit on this. I like to have about 5-10psi more back pressure than boost on the pulling track - this allows me to continue putting enough power into the turbo to keep the turbo "lit" at the big end of the track. For street driving I tend to put the heaviest spring in the waste gate I can get - then put regulated boost to the top of the gate and put unregulated boost to the bottom of the gate. By adjusting the amount of regulated boost I can control when the waste gate opens. By changing springs to a softer spring, or decreasing the pre-load on the spring you can adjust how "hard" the boost hits - by going to a softer spring the waste gate will open just a bit during large increases in back pressure that occur when you stab the throttle - I like mine a bit more hard hitting than some. Another option that is more associated with competition is to build a back pressure blow off valve - basically use a waste gate and install a spring with enough force to hold the gate closed until the back pressure reached your desired goal - for instance through testing you might know you will have 55-60psi of back pressure at 50psi of boost - then you just adjust the spring pressure and pre-load until the waste gate blows itself open at 55-60psi of back pressure - once it gets there it opens - no matter what boost is doing.
