Turbosmart Volkswagen/Audi MSG50 Modular StraightGate50

Turbosmart is well-known for making robust boost control components, and their StraightGate50 external wastegate is a prime example of that focus. This particular model, the MSG50, is designed specifically for certain Volkswagen and Audi applications, offering a direct way to manage boost pressure more precisely than the factory setup. If you're looking to fine-tune your turbocharger's performance, especially on a modified engine where the stock wastegate might be a limitation, this is a solid option.

The StraightGate50 features a 50mm V-band inlet and outlet, making it adaptable for various plumbing configurations. It's built with a stainless steel V-band clamp and a billet aluminum actuator housing, which are strong materials that can handle the heat and pressure associated with forced induction. Inside, a silicon-bronze diaphragm is used, which is known for its durability and resistance to fuel and oil contamination. This wastegate comes with a variety of springs, allowing you to set different boost pressure targets right out of the box. You'll typically use the included springs to achieve your desired boost level, or you can combine them for even finer control. Installation involves plumbing it into your exhaust system before the turbocharger and connecting the vacuum line to your boost source.

Because this wastegate is not CARB approved, it cannot be shipped to California. Make sure to check your local emissions regulations before purchasing. This wastegate is a significant upgrade for anyone serious about controlling their turbocharger's boost levels effectively.
