i have a question about dual wastegates i only want experienced answers no guesses as this is a very expensive set up i dont wanna wastemoney i have a z6 fully built bottom end mid deck slleves cp pistons and custom made manley rods and a costom forged crank if it can be done enternally it has been so dont make any remarks bout to much boost or power i am currently running a precision ceramic sc61 35 psi with well over 550hp and i have boost creep with an excellent tune i am runnig a custom top mount now it already has dual wastegate capability ( i am running extremely low compresion and getting a retune no stupid comments it can be done) will the dual wastegate get rid of this creep or should i keep it simple and get a bigger wastegate i can send the manifold back for a bigger flange i have a 44 mm right now PLEASE NO GUESSES I DONT WANNA READ ALL NIGHT believe it or not this is a daily driver i am runnig a aem standalone I AM NOT CHANGING MANIFOLD SO DONT SAY THAT I HAVE HEARD THAT FROM A FEW PEOPLE THAT IS NOT THE PROBLEM

 

dual wastegates will require a split turbo manifold. this will help spool the turbo up quicker but its expensive and will require a new manifiold. since your not willing to do this just get a larger wastegate. before you do check your wastegate boost reference line and make sure its connected from a vacuum source close to the intake manifold. if yours is connected directly from the turbo compressor housing boost creep can occur.

 

First question is the turbo Twin scroll , if yes , yes get duel , if no go bigger , either way , it will eliminate the creep , oh oh oh all i have to say is (pie, R, square ) the bigger the hole ,weather duel or single , will flow more and thus eliminate the pressure

 

not twin scroll got it figured out thankyou busa4

 

your welcome.
