It provides reliable operation with high flow capacity to maintain consistent boost levels under demanding conditions.
Key Features
- Compact 40mm Design: Smallest footprint in its class allows installation in confined engine bays without compromising flow or performance
- Liquid-Cooled Actuator: Stainless steel housing with water cooling ports keeps actuator temperatures low for consistent response and extended durability
- Nitronic 60 Valve and Stem: Hardened material resists wear and heat for thousands of cycles without fatigue or sticking
- Patented Locking Ring: Secure valve seating prevents boost creep and ensures quick response across the full RPM range
- V-Band Clamps: Inlet and outlet use stainless V-band system for leak-free seals and easy disassembly during maintenance
Product Notes
- Welding required for V-band flanges on turbo manifold and downpipe
- Includes 14 PSI red spring, additional springs available separately for tuning
- Ships fully assembled with all fittings and hardware for immediate installation
Installation Notes
- Professional installation recommended.
- Water cooling lines must be connected if actuator cooling is used
- Compatible with standard V-band dump pipes and 347 stainless steel housings

Forced Induction
Forced induction systems encompass every method of pushing air into an engine at greater than atmospheric pressure, including turbochargers driven by exhaust energy, superchargers driven mechanically by the crankshaft, and prochargers using centrifugal designs belt-driven at higher ratios than traditional roots-type blowers, with each approach delivering a significant increase in air mass per cylinder fill that allows proportionally more fuel to be burned and more power to be produced without increasing engine displacement. Adding 10 PSI of boost pressure to a naturally aspirated engine can increase power output by 50 to 70 percent depending on the engine's breathing efficiency and the quality of the supporting hardware, making forced induction the most power-dense modification available relative to cost and complexity. This collection covers complete forced induction systems, turbocharger and supercharger hardware, intercoolers, blow-off valves, wastegates, and supporting component...
