These TiAL Wastegate Springs are for use in TiAL MV-S and MV-R wastegates. All TiAL wastegate springs are constructed from 17-7 PH Stainless Steel which is capable of maintaining consistent pressures up to 900 Deg F (483 Deg C). Please see the information below to decide which spring(s) you need for your application. The boost pressures are approximations from TiAL based on equal intake and exhaust manifold pressures, results will vary slightly for different applications. Higher pressure settings will require the use of multiple springs working together. In these multiple spring setups the resultant pressure is equal to the sum of the individual springs.
Please Note:
The blue (old color: maroon) and white (old color: copper) are designed to work in multi-spring applications to obtain the pressure ratings listed for the MV-S wastegate, they are not designed to be used individually with the MV-S. However, the blue (old color: maroon) spring may be used individually with the MV-R wastegate. The plain spring is to only be used with the MV-R wastegate.
TiAL F38, F40, F41, V44, F46, and V60 wastegates require the use of springs specific to those wastegates.
TiAL has changed their spring colors for easier identification:
- Black replaces Grey
- White replaces Copper
- Red replaces Gold
- Blue replaces Maroon
- Yellow replaces Beige
- Green replaces Brown
- Plain remains unchanged
