The TiAL Sport MV-I 2.5 is a compact internal wastegate actuator that regulates turbine bypass to hold a target boost pressure, with a stiffer spring raising base boost and sharpening response. It carries a 17-7 PH stainless steel spring that stays consistent to 900F, a high-temperature Nomex-reinforced silicone diaphragm, M8 air ports and a 1/4-UNF threaded stem on a universal two-bolt mount. This unit is finished in black, uses the 18 PSI spring, and ships with the straight rod. The straight-rod stem suits inline linkage layouts.
