I have a A full race kit with a 44 wg, I also have a built bottom end. I am have some issue with boost kreep. My tuner put a boost cut off so when I get boost kreep it cuts off boost, more for a saftey thing. I want to go back to raise the boost cut off to 20 it is set at 17. So would a boost controller help in my case to keep it under 17 psi?

 

Well are you using a AEM to control your boost or a boost controller. I would think they are using the AEM or your EMS. Then you will need to make a change there. Why don't you just get a bigger WG?

Update: I did switch to the newer turbosmart 38 WG. It did not solve the creep 100% but it is a lot better now and much more manageable.

 

its that simple lol. you have a whole lot of wastegate there. I dont think you have anything to worry about as far as creep and arent you using aem to control boost? If thats the case Evans will just turn duty cycle down to get the car to hold steady in the winter months.

 

I think the quoted answer is abit missleading. Firstly, two 38mm WGs is NOT the same as one 76mm WG. Two 38mm WGs will have the flow area of 22,6 square centimeters, while one 76mm (theoretical WG) would have a flowarea of 45,3 square centimeters.
Infact, a 50mm WG is almost as "big" as two 38s.

Secondly, the minimum dutycycle of EBC usually increases boost. Not much but significant if there already is creep you want to avoid. I have experience with Kpro and the lowest duty cycle made it impossible for me to run EBC, had to go without to minimize creep at high rpms. (until manifold is rebuilt).
