Spring Pressure Rate (bar/psi)*:

These springs can be used for either 38mm or 40mm Tial wastegates. The small springs range from .25 bar (3.63psi) to .60 bar (8.7psi) and the large range from .7 bar (10.15psi) to 1 bar (14.50). Small springs (1.875"dia) and large springs (2.36"dia) can be combined to give you a stiffness of over 1 bar or 14.5psi. A small spring cannot be used together with another small spring, a small spring can only be used with a large spring. The same goes for the large spring which cannot be used with another large spring. A small or a large spring can be used independantly for pressures ranging from .25bar (3.63psi) to 1 bar (14.5psi).  When combining a small and large spring the spring strengths are simply added together to give you your new spring strength for the combination. For example, a .5 bar small spring when added to a .9 bar large spring will give you a result of 1.4bar. The combination of a small spring and a large spring will range up to 1.6 bar (23.20 psi). If you have any questions or need any help in choosing your spring pressure rate for your tial 38mm or 40mm wastegate feel free to contact us at StreetUnit Performance.
