💨 Engineered for Efficiency – How It Works
The DNA 40mm External Wastegate regulates boost by diverting exhaust gases away from the turbocharger once a preset boost level is reached. This allows you to control turbo speed and maintain consistent boost without over-stressing your engine or turbo system.
The 40mm valve size provides the perfect flow for mid-to-high horsepower applications, ensuring precise control and smooth power delivery whether you’re at full throttle or part-load.
Key Performance Features:
-
40mm stainless steel valve for superior heat resistance
-
Anodized billet aluminum actuator housing for durability
-
High-temperature silicone diaphragm for consistent performance
-
Multiple spring options for adjustable boost levels
-
Designed to fit most T3, T4, and custom turbo manifolds
With the WG-TS-40MM-T11-PP, you get precise boost management, reduced turbo lag, and greater reliability — all in one compact, race-ready unit.
Waste gates provide a means to control the boost pressure of the turbo charged engine. Waste gates work to bypass exhaust flow from the turbine wheel. Bypassing the exhaust flow reduces the power driving the turbine wheel to match the power required for a given boost level. Similar to the BOV, the Waste gates uses boost pressure and spring force to regulate the flow bypassing the turbine. Waste gates are bolted to exhaust manifold or header. The advantage of external Waste gates is that the bypassed flow can be reintroduced into the exhaust stream further downstream of the turbine. This tends to improve the turbine’s performance.
🔩 Built to Handle High Boost and Heat
Performance is nothing without durability — and the DNA 40mm Wastegate is built to last. Its stainless steel valve and flanges are designed to withstand extreme exhaust gas temperatures, while the CNC-machined aluminum housing ensures perfect sealing and minimal wear over time.
