Pulsar Turbo Systems 45mm Dual V-Band External Wastegate

Multiple Wastegate Spring Options

The included spring kit allows the wastegate to be configured for different baseline pressure requirements.

The supplied listing states spring pressure accuracy of approximately ±0.5 PSI.

Wastegate spring pressure represents the mechanical baseline of the wastegate and does not necessarily equal the final boost pressure produced by the vehicle. Actual boost depends on the complete turbocharger system and boost-control strategy.

Dual V-Band Configuration

The Pulsar 45mm wastegate uses V-band connections on both the inlet and outlet sides.

The supplied package includes the corresponding inlet and outlet flange-and-clamp kits, helping simplify installation when the turbo manifold and exhaust system are designed for the appropriate configuration.

Flange Specifications

Always verify these dimensions against your turbo manifold and exhaust fabrication before ordering.

Adjustable Actuator Position

The actuator position can be adjusted to accommodate different installation requirements. This can be useful when packaging the wastegate around custom turbo manifolds, exhaust components, and engine-bay hardware.

Proper actuator alignment is important for reliable wastegate operation.

High-Temperature Diaphragm

The actuator uses a high-temperature silicone diaphragm reinforced with Nomex, designed for the demanding thermal environment associated with turbocharged applications.

The wastegate also uses chrome steel components for the seat, valve bushing, housing, and flanges.

Specifications

Installation & Compatibility

This is a performance-oriented external wastegate intended for compatible turbocharger systems rather than a vehicle-specific direct replacement.

Before purchasing, verify:

• 45mm wastegate compatibility
• Inlet and outlet flange dimensions
• V-band configuration
• Air-port requirements
• Spring pressure requirements
• Actuator clearance
• Wastegate placement
• Exhaust discharge routing

Professional installation is highly recommended. Follow the manufacturer’s installation instructions for proper operation.
