These TiAL® Wastegate Springs are for use in TiAL® F38, F40, F41, V44, F46, and V60 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 both small and large diameter springs working together. In these dual spring setups the resultant pressure is equal to the sum of the individual springs.
Please Note:
TiAL® MV-S and MV-R wastegates require the use of springs specific to those wastegates which can be found here.
