Installation Instructions
Note: The optimum mounting and placement of your new PW66 wastegate will be determined by your manifold
and turbocharger configuration. These notes should be considered when installing your new wastegate.
-
Be sure to install the valve seat into the body of the wastegate before final installation.
-
Tighten the supplied V-band clamp bolts to 85-90 inch /lbs (9.6 – 10.2 Newton meters).
-
In order to assure proper boost control, your PW66 wastegate needs to be mounted at a smooth
transitional angle with the exhaust flow. 90° mounting onto exhaust tubing is not recommended. Refer to
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.
-
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 atmosphere. Note that venting to
atmosphere only applies to OFF ROAD VEHICLES. Venting wastegate exhaust to atmosphere may be
ILLEGAL and considered to be emissions related tampering under applicable laws, rules and regulations.
