I made a stainless linkage that replaces the boost actuator normally installed on the QSV. It is controlled by a high torque and high speed titanium geared RC car servo motor by HiTec (HS-7940TH). During the test, I have it powered by one of my rc cars just to show the proof of concept and verify it all works properly. It will be wired to my Haltech ecu for full map control. The advantages are that the valve can remain open allowing exhaust to freely flow out without choking and building up too much unnecessary heat when boost isn't wanted. An example of this is during any engine revs above 3k like highway cruising, I will no longer see 1-2psi of boost when I barely tip the throttle. It will also allow for crisper engine response, more power, and better economy when off boost. I will program the Haltech to activate (close) the spool valve whenever I press the throttle anywhere over 35% and current map readings are below the target boost level. The reduced heat should also extend the life of this valve far longer than my last one. In the video, it isn't all that noticeable, but the exhaust is very noticeably louder when the valve is open vs closed.
