TiAL Sport MVR Wastegate 44mm 14.5 PSI w/Clamps - Black 003414

TiAL Sport MVR Wastegate 44mm — Black, 14.5 PSI w/Clamps (003414)

The MVR is TiAL's 44mm V-band wastegate, and the size is the reason to reach for it. When a 38mm gate starts creeping on a larger turbo or a big-displacement engine, the extra flow area is what lets you hold your target instead of chasing boost spikes with the controller.

V-band inlet and outlet mean you can clock the gate wherever the header run puts it, which matters on a tight manifold where a bolt-flange gate would dictate the whole design. Aluminum body, black anodized, with the same replaceable spring architecture as the rest of the TiAL line.

Ships with a 14.5 psi spring, which puts base pressure high enough to be useful on a serious build without needing a swap out of the box. Springs are interchangeable if you want to land somewhere else.

Sizing: the right call on a big single, a V-configuration running dual gates, or any setup where the exhaust flow past the turbine is more than a 38mm valve can bleed off.

Not CARB legal. Not for sale in California.

Includes the wastegate, both V-band clamps, and flanges.
