INSTALLATION INSTRUCTIONS –
Evolution Wastegate
IMPORTANT
: Read instructions completely before proceeding. Engine or
turbocharger
damage may occur
if any wastegate is improperly applied or installed. Consult a knowledgeable turbo installer or Turbonetics
tech support specialist with any questions about correct wastegate application or installation.
SUMMARY
: Turbonetics’
Evolution Wastegate
has been specifically designed to advance the “state of the art”
in modern wastegate design. Properly applied and installed, it can reliably control turbocharger boost pressure in
high-performance applications up to 400 horsepower per turbo (800 HP for twin turbo). Design features include:
Investment cast stainless steel housing
“Floating” valve seat, which also serves as the inlet seal
1.38” (35mm) diameter valve, made from a special “corrosion & galling resistant” stainless steel
Fabric-reinforced “rolling” diaphragm
Set-screw spring preload adjustment
Polished & painted actuator cover
The
Evolution Wastegate
has also been specifically designed to directly replace the Deltagate wastegate,
offering the benefits of reduced size, lighter weight, increased flow and better control.
OPERATION
: The
Evolution Wastegate
controls turbocharger boost by bypassing the turbine inlet gas flow in
response to the actuator spring load and/or boost level control signal. The actuator section is fitted with sensing
ports on both sides of the diaphragm, allowing precise control of valve motion, and use of any optional external
variable boost controller, manual or electronic. A choice of actuator springs is included, to suit specific application
requirements.
