Thank you for purchasing our PW39 external wastegate. With over 60 years of combined turbocharger
development and racing experience, we at Precision Turbo take great pride in providing you with the
best external wastegate on the market today. The PW39 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. Our investment cast valve body
has a smooth internal surface, giving you better flow and more accurate boost control. Our PW39 was
designed to be a direct replacement for other existing 38mm wastegate flanges, but will work best with
the flange provided. The PW39 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 PW39 is generally compatible with most aftermarket manual and electronic
boost controllers on the market today. If you have any questions or need any technical support, our
experienced Sales Staff are here to help.
