Features & Product Details
This is the white Tial blow off valve spring for the Alpha Q 50mm, as well as the Q blow off valve. The pressure of the spring is determined by the amount of vacuum your motor has at idle, and does not correlate to boost pressure. If your blow off valve is not sealing at idle, then you will need a heavier spring.
For the Alpha Q, and 50mm Blow Off Valve, the white spring reading rate is -11 PSI (-22 in/Hg) -14 and -17 in/Hg.
The Q blow off valve readings are -10 PSI (-20 in/Hg) -12 and -15 in/Hg.
