Tial 38mm External Wastegate Spring Small Yellow 0.25 Bar
BAR PSI DESCRIPTION O.D.
0.250 3.626 Small Yellow 1.875 In
Tial 38mm external wastegate comes standard with the 0.5 Bar Spring (~7 PSI). You can select different springs for additional boost and combine a SMALL & LARGE spring to go beyond 1.0 BAR. For example, combine a 0.5 BAR (Small Green) with 1.0 BAR (Large Blue) spring, and you'll get 1.5 BAR combination.
*Made specifically for the F38 & WG38 Tial Wastegate.
YOU CAN ONLY INSTALL A MAXIMUM OF 1 LARGE AND 1 SMALL SPRING PER WASTEGATE!
*This spring will not work with MVS Wastegates.
** Higher Pressure Settings require the use of both
Small and Large diameter springs. When using a Dual
Spring setup the resultant pressure is equal to the sum
of the individual springs.
Note: Boost pressures are only an approximation
based on intake manifold pressures equaling exhaust
manifold pressure.
