INSTALLATION MANUAL
AEROFLOW PERFORMANCE
EXTERNAL WASTEGATE
WARNING!
BEFORE PROCEEDING WITH INSTALLATION PLEASE READ INSTRUCTIONS CAREFULLY. THIS PRODUCT REQUIRES
DETAILED KNOWLEDGE OF AUTOMOTIVE SYSTEMS. WE RECOMMEND THAT THIS INSTALLATION BE CARRIED
OUT BY A QUALIFIED AUTOMOTIVE TECHNICIAN.
Use caution when working on a hot engine. Wastegate and turbocharger components are EXTREMELY HOT
and can cause severe burns.
Fitting this wastegate may require fabrication or modification to your exhaust manifold.
This wastegate is designed for use with a turbocharger that does not have an internal wastegate.
Aeroflow Performance recommends that the engines Air/Fuel ratio is checked while setting the desired boost
pressure, as any increase in boost pressure can cause the engine to run “LEAN”, resulting in possible engine
damage.
Aeroflow Performance recommends that boost pressure is set using a dynamometer and not on public roads.
INTRODUCTION

customer, products that perform properly and satisfy your expectations. Should you have any questions?
Please call technical support at +61 2 8825 1900 and have the product part number on hand when calling.
Aeroflow Performance wastegates are designed to control the turbochargers boost by bypassing turbine inlet
exhaust gas via a spring loaded valve diaphragm assembly. Spring rate, in conjunction with boost pressure
signal and back pressure, control 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 turbines wheel speed. This stabilization results in a
smooth and steady boost pressure level, created by the compressor wheel of the turbocharger. 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.
