What is the purpose of an external wastegate?

An external wastegate controls the maximum boost pressure your turbocharger can produce. It diverts excess exhaust gas away from the turbine wheel when a set pressure is reached, preventing the turbo from spinning too fast and over-boosting the engine.

What does the 1.49 Bar spring mean?

The 1.49 Bar (21.61 PSI) spring is the base boost pressure the wastegate will aim to maintain without any additional boost control. You can use this spring alone for a fixed boost level or combine it with an adjustable boost controller for finer tuning.

Can I use this wastegate on a California vehicle?

No, this wastegate is not CARB approved and cannot be legally shipped to or installed on vehicles in California.

Product Details

If you're building a custom turbo system or upgrading an existing one, controlling boost pressure is critical for engine health and performance. The TiAL Sport V50 50mm external wastegate is designed to precisely manage that boost, ensuring your turbocharger operates within safe and efficient limits. This wastegate helps prevent over-boosting, which can lead to engine damage, and allows you to dial in the exact boost level your setup needs.

This V50 model features a robust 50mm diaphragm and a 1.49 Bar (21.61 PSI) spring, offering a solid starting point for many boosted applications. The diaphragm is made from a high-temperature silicone-reinforced fabric, built to withstand the harsh conditions of exhaust gas. The wastegate body is constructed from billet aluminum for strength and light weight, while the internal components are designed for durability and consistent operation. The purple anodized finish not only looks sharp but also adds a layer of corrosion resistance.

Installation involves plumbing the wastegate into your exhaust manifold and connecting the boost control line to your intake manifold or boost controller. Proper setup is key to achieving the desired boost levels and ensuring the wastegate functions as intended. This unit is a popular choice for tuners and builders looking for reliable boost control in high-performance applications. Please note that this wastegate is not CARB approved and cannot be shipped to California.
