What is the purpose of a wastegate?

A wastegate controls the maximum boost pressure your turbocharger can produce. It diverts exhaust gases away from the turbo's turbine wheel when a set pressure is reached, preventing the turbo from spinning too fast and creating excessive boost.

Can I change the boost pressure on this wastegate?

Yes, the TiAL Sport MVR wastegate is designed to allow for spring changes. You can swap out the included .9 Bar spring for different rated springs (sold separately) to adjust your target boost pressure.

What is required for installation?

Installation requires custom exhaust fabrication to plumb the wastegate into your manifold or header, and a boost signal line connected to your intake manifold or boost controller. Refer to the manufacturer's installation guide for detailed instructions.

Product Details

If you're building a turbocharged engine and need precise control over boost pressure, a well-built wastegate like the TiAL Sport MVR is essential. This 44mm unit comes pre-set with a .9 Bar (13.05 PSI) spring, making it a popular choice for managing boost levels in a variety of performance applications. It's designed to work with external plumbing to vent excess exhaust gas away from the turbocharger's turbine, preventing over-boosting and keeping your engine running safely and efficiently.

The MVR wastegate is known for its solid construction and reliable performance. It features a high-temperature resistant diaphragm and a robust actuator assembly that can handle the demanding conditions found in a performance engine bay. The anodized black finish not only looks sharp but also adds a layer of corrosion resistance. Installation involves plumbing it into your exhaust manifold or header and connecting the boost signal line to your intake manifold or boost controller.

Keep in mind that this wastegate is not CARB approved and cannot be shipped to California. Always refer to your vehicle's specific service manual and local regulations for proper installation and emissions compliance.
