The TiAL Sport MVR 44mm wastegate is spring-rated to 1.3 bar (18.85 psi) and finished in black (MVR-1.3BK). It releases high boost pressure to protect forced-induction engines and keep boost control predictable at elevated targets. Verify the part code for the higher spring rating when building higher-boost setups where robust pressure control is required.
