Yeah not the cheapest piece of brass out there. But it exsist for those that can't or don't want to make one.

you can get an adjustable fitting from ANY hydraulics shop that deals with construction or machinery. Idealy a garrett 'T' series should stay below 45-50.. ( not sure where corky bell got 25psi from in his book..) at boost and 5psi at idle.





just an FYI
