Epman Greddy RS type Recirculating Blow Off Valve

A blow-off valve is a device for releasing pressure in the intake manifold to prevent turbo compressor surge. When the throttle closes rapidly, the airflow quickly decreases, causing flow instability and pressure fluctuations. Surge can eventually lead to damage to the thrust bearing due to the high loads associated with it. Blow-off valves use a combination of manifold pressure signal and spring force to detect when the throttle is closed.

Features:
Universal 40mm RS style.
CNC machined from cast aluminum with an anodized finish
Opposing spring design allows for improved control, response, and idle
Easily adjustable to eliminate compressor surge and prevent premature pressure leakage, while increasing boost response between shifts.
Withstands up to 30 PSI of pressure.
Range 100-420 hp

Application:
Compatible with standard 2-bolt BOV flanges and RS type outlet adapters.
Turbo engines only!

Turbosmart Kompact 25mm blow-off valve, genuine
 
Genuine Turbosmart product – a fully recirculating BOV. The Plumb Back system recirculates all excess pressure back into the intake system. Suitable for enthusiasts who don't want to be noticed but want the performance and reliability benefits of a quality blow-off valve.
 
Most factory blow-off valves on mass-produced cars are made of plastic, unlike the incredibly durable machined construction of the Kompact series. Standard valves often fail to eliminate damaging compressor surge, and as cars age, the plastic becomes brittle and can crack, causing serious boost leaks. This prevents the turbo from reaching its full potential, robbing you of power.
 
With its anodized aluminum body and lightweight alloy piston, the Kompact offers exceptional durability, superior response, and excellent boost holding capability for its size.
 
The Kompact Dual Port is perfect for owners of stock to lightly modified cars.
 
Included:
 
Spring up to 0.6 bar (fitted)

The award-winning Compact EM series of upgraded blow-off valves are the world's first true plug-and-play upgrade solution for your factory valve. Disconnect and unbolt your OEM valve and install the Kompact EM. No adapters, hoses, or additional installation are required.
The Kompact EM valve series from Turbosmart uses motorsport-proven technology and adds a built-in proprietary solenoid system and internal pressure control channels. No reference hoses, separate solenoids, or useless parts – just bolt on and plug in!
You can count on unparalleled performance and reliability as a direct replacement for your factory BOV. Kompact EM valves overcome common failures associated with plastic factory valves through our boost-balance valve design (the more boost you have, the better it seals), a positive sealing O-ring on the piston face, and billet construction. Whatever your application, the Kompact EM series will maintain more boost and be more responsive in any environment.

The legend continues! Turbosmart's VeePort Pro is an evolution of the original VeePort, now 20% smaller and 33% lighter. Based on Turbosmart's BOV5 architecture, the VeePort Pro offers huge performance. Built on our motorsport proven Boost-Balance system utilizing a 38mm piston, this valve can easily flow up to around 600 HP when needed and hold as much boost as you can throw at it.
