Unlike brightly colored wastegate configurations, the Sleeper Black finish complements dark engine bay components, black intercooler piping, and other stealth-inspired performance hardware.
The Sleeper version retains the same fundamental 45mm valve size and boost control functionality as the corresponding standard HyperGate45 Lite configuration.
45mm External Wastegate Valve
The HyperGate45 Lite utilizes a 45mm valve to regulate exhaust gas bypass flow.
When the wastegate opens, exhaust gas is diverted around the turbocharger turbine.
This reduces the amount of exhaust energy driving the turbine and helps maintain the intended boost pressure.
The 45mm configuration is suitable for many medium-to-large turbocharger applications.
However, wastegate sizing must be matched to the engine's exhaust flow, turbocharger characteristics, manifold design, and intended boost pressure.
14 PSI Preinstalled Spring

Proper actuator positioning also helps keep pressure reference hoses away from excessive exhaust heat.
1/8-Inch NPT Pressure Reference Ports
The GenV HyperGate45 Lite incorporates 1/8-inch NPT pressure reference ports.
These ports allow the wastegate to be connected to a compatible boost pressure source or boost control system.
Depending on the selected control arrangement, the upper and lower actuator chambers may be connected differently.
Unused ports must be sealed with the appropriate plugs.
Always follow Turbosmart's recommended pressure plumbing diagrams.
V-Band Inlet and Outlet Connections
The HyperGate45 Lite uses V-band mounting connections on both the inlet and outlet.
V-band clamps provide secure connections while allowing convenient wastegate removal for servicing.
The included stainless steel weld flanges allow the wastegate to be integrated into compatible custom exhaust manifolds and dump tubes.
Correct flange alignment and proper welding procedures are essential for reliable installation.
Strap-Style V-Band Clamps
The GenV HyperGate45 Lite includes strap-style V-band clamps.
These clamps provide secure mechanical connections between the wastegate and its mounting flanges.
The design supports reliable clamping while maintaining a compact installation profile.
Optional Liquid Actuator Cooling
The GenV HyperGate45 Lite supports optional liquid actuator cooling.
This feature can help manage actuator temperatures in demanding turbocharger installations.
Liquid cooling may be beneficial when the wastegate is positioned close to high-temperature exhaust components or operates under sustained heavy loads.
