TiAL Sport V50 Wastegate 50mm 1.02 Bar (14.79 PSI) - Black

This is the TiAL Sport V50 50mm external wastegate, set to control boost pressure at 1.02 Bar, which is about 14.79 PSI. It's finished in black and is designed for turbocharged applications where precise boost control is essential. External wastegates like this one work by bypassing exhaust gas around the turbine wheel, allowing you to manage and limit the maximum boost pressure your turbocharger can produce. This helps prevent over-boosting, which can damage your engine, and allows you to tune for optimal performance and reliability.

The V50 wastegate features a 50mm diaphragm and valve assembly, making it well-suited for higher horsepower applications that require significant exhaust flow management. TiAL is known for well-built components in the forced induction world, and this wastegate is no exception. It uses a high-temperature silicone diaphragm and a stainless steel valve seat, designed for durability under extreme conditions. The unit comes with a 1.02 Bar (14.79 PSI) spring installed, but you can easily swap it out for different spring combinations to achieve different boost levels, offering a lot of tuning flexibility. The black finish not only looks good but also offers a layer of protection against the elements.

When installing an external wastegate, you'll typically need to weld a flange onto your exhaust manifold or downpipe to mount it. It's important to ensure proper plumbing for both the boost signal line to the top of the diaphragm and the exhaust dump tube to route the bypassed gases safely away. This wastegate is not CARB approved and cannot be shipped to California.
