The TiAL Sport MVR is a 44mm V-band external wastegate that controls boost by venting exhaust gas around the turbine, rated 50 lb/min. It is built from stainless steel and aluminum with a purple CNC-machined actuator housing, a Nomex-reinforced silicone diaphragm, a multi-port diaphragm chamber and internal M8 coolant passages that keep diaphragm temperature in check. The gate ships with a 14.5 PSI spring, and its full V-band flange set makes for flexible fitment and easy clocking.
