heat and pressure
The heat is radiant and my pressure rating is upwards of 10,000 psi in my weakest fitting. Thats the plus side of hydraulic fittings. Good ratings and moderate to good heat resist. Something to consider is my SAS system was most likely off during my throttle kick test. this is because I have not established control from the ECU quite yet and its operating like a blow off valve in to the exhaust manifold.
The reason I need to have a throttle kick is to relieve some of the back pressure on the intake tract to counter surge, essentially raising the surge line for that area of operating. This means higher shaft speed and better boost recovery in my mind. Over spinning a stock framed journal bearing turbo is the last of my concern.. If my hta 71 bites the dust Ill look for a stock frame turbo and enjoy
I know this goes back from the idea of fresh air etc .. but Im gonna do what works and name it later!
