Product Details

Tial 38mm External Wastegate Spring Options 0.25-1.60 bar/3.6-23.2 psi

 

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.
