PTE Gen2 46mm Wastegate

Let Precision PTE Gen2 PW46 46mm Wastegate Control Boost Pressure and Get the Most Out of Your Turbo

Precision's high-quality yet economical PW46 46mm external wastegate is for the automotive enthusiast looking to get the most from their turbocharged car, truck, or any other vehicle. The PW46 is made from high-grade, high-temperature stainless steel and billet aluminum components. It features our own purpose-designed Kevlar reinforced wastegate diaphragm and a 347 stainless investment cast valve body. The company's cast valve body has a smooth internal surface, providing better flow and more accurate boost control.

The PW46 was designed to be a direct replacement for other existing 44mm wastegate flanges but will work best with the flange provided. The PW46 features a nickel-chromium alloy valve and 5 different 17-7 precipitation hardened springs. Also included are stainless steel inlet and outlet flanges. With a satin black anodized, 6061 aluminum billet wastegate cap you will have years of good looks and protection from the elements. The PW46 is generally compatible with most aftermarket manual and electronic boost controllers on the market today.

With over 60 years of combined turbocharger development and racing experience, Precision Turbo knows what it takes to make quality parts and upgrades, and this Gen2 PW46mm Wastegate is no exception.

PW46 External Wastegate Overview

The PW46 wastegate controls turbocharger boost by bypassing turbine inlet exhaust gas via a spring-loaded valve diaphragm assembly. The spring rate, in conjunction with boost pressure signal and back pressure, controls the opening point of the wastegate valve. Once the spring rate has been overcome, the valve will open.

This causes exhaust flow to be diverted away from the turbine side of the turbocharger, effectively slowing and/or stabilizing the turbine wheels’ speed. This stabilization results in a smooth and steady boost pressure level, created by the compressor wheel of the turbocharger. The open pressure of the valve can be controlled via spring rate and or a boost controller, such as a manual boost controller or an electronic boost controller.

PW46 External Wastegate Installation Instructions:

The optimum mounting and placement of your new PW46 wastegate will be determined by your manifold and turbocharger configuration. Consider this when installing your new wastegate.

The PW46 wastegate is compatible with TiAL's 44MM wastegate weld flange, for a trouble-free bolt-on replacement.
Be sure to install the valve seat into the body of the wastegate before final installation.
Tighten the supplied bolts to 85-90 inch /lbs (9.6 – 10.2 Newton-meters).
In order to assure proper boost control, your PW46 wastegate needs to be mounted at a smooth transitional angle with the exhaust flow. 90° mounting onto exhaust tubing is NOT recommended. Refer to the diagrams below.
Inlet and Outlet flanges are constructed of, 304 stainless steel and are compatible with most stainless steel and mild steel welding rod material.
It is recommended to secure all vacuum and or boost control hoses securely with zip ties or cushioned clamps. Route all vacuum hoses away from high heat sources such as the turbine housing and exhaust manifold.
Your PW46 wastegate includes two hose barb banjo assemblies and one pressure port cap. Allowing you to install the lower hose barb banjo assembly in one of two locations, depending on your wastegate mounting position.
Allow for cool airflow around the top billet wastegate cover.
Use caution when working on a hot engine. Wastegate and turbocharger components are EXTREMELY HOT and can cause severe burns.
Wastegate outlet can be routed back into the exhaust system or vented to the atmosphere. Note that venting to the atmosphere only applies to OFF-ROAD VEHICLES. Venting wastegate exhaust into the atmosphere may be ILLEGAL and considered to be emissions-related tampering under applicable laws, rules, and regulations.

Warning

Fitting a heavier wastegate actuator spring may cause a higher than expected increase in boost pressure.
Use of a turbocharger speed sensor is a good idea if you plan to run very high boost levels
