Wastegates – Precision Boost Control for Maximum Performance

Regulate exhaust flow and prevent over-boosting with high-quality wastegates. Perfect for high-performance turbo setups.

PSR Wastegate Fitment & Boost Control Guide

Selecting the right external wastegate is the most important step for maintaining stable boost control and protecting your turbocharger from over-boost. Whether you are running a turbo with wastegate internal setup or a high-horsepower external wastegate manifold, having the correct valve size and spring pressure ensures your build remains reliable under load.

Our range of turbocharger wastegate solutions, including 38mm, 45mm, and 60mm units, are designed to reduce boost creep and provide precision tuning. To complete your wastegate turbo installation, ensure you match your wastegate to the correct flange kits and wastegate blankets for optimal heat management and sealing.

  • Size Selection: Match your wastegate diameter to your turbocharger frame and power goals.
  • Fitment: Confirm whether your manifold requires a 2-bolt or V-band mounting style.
  • Heat Control: Use titanium blankets to protect engine bay components from high exhaust temperatures.

Wastegate FAQ

  • What is the benefit of an external wastegate? An external unit offers superior flow capacity and more precise boost control than most internal setups, especially in high-flow applications.
  • How do I prevent boost creep? Using a correctly sized wastegate—like a 45mm or 50mm unit—ensures enough exhaust gas can bypass the turbine to maintain your target pressure.
  • Are PSR wastegate flanges universal? While many use standard V-band sizing, it is always best to use the matching PSR flange and clamp kits to ensure a leak-free seal.
