Product information

Nuke Performance Blow Off Valve 50 mm Hose Connection is an atmospheric piston valve type with the highest flow capacity available.

When it is necessary to be able to rely on the installation and function. The Nuke Performance Blow Off Valves is available with either a 50mm hose connection or a 3" V-Band connection. For serious boost, and serious power.

 Lightweight Blow Off Valve
 50mm / 2" hose connection or V-Band connection
 0.35 - 0.50 BAR setup spring is preinstalled
 50mm piston valve design
 1/4" reference vacuum port
 Made in Sweden

It's ready for some serious boost, and some serious power. Either installed in a single setup or in a dual setup when one isn´t enough. It´s designed with an oversized 50 mm valve, we believe this is the largest valve available with the highest flow capacity for an atmospheric blow-off valve.

 

 Easy to connect to your intake with either the 50mm (2") hose connection or with V-Band, available with both options
The Nuke Performance Blow Off Valves is available with either a V-band connection, where both the needed lightweight aluminum clamp and the aluminum weldable flange are included. If you prefer, the hose connection version suits a common 2" (50mm) silicon hose, easy to install without the need for welding and custom manufacturing.

 

 Choose the right setup spring for your engine setup
The Nuke Performance Blow Off Valve 50 mm V-Band comes with a setup spring preinstalled, the 0.35-0.50 BAR spring is the most common and popular spring and used by most of our customers.

0.50 - 0.75 bar (7.25 - 10.9 PSI) : Additional BLACK SPRING (Part #: 900-01-104)
0.35 - 0.50 bar (5.07 - 7.25 PSI) : Premounted BLUE SPRING (Part #: 900-01-103)
0.00 - 0.35 bar (0.00 - 5.07 PSI) : Additional WHITE SPRING (Part #: 900-01-102)

To find out which spring suits your build the best, you measure engine vacuum at idle and with the engine at operating temperature. It is easy to swap the setup spring when needed, you only need a 5mm hex key.

 

 Delivered with a 6mm pneufit quick connect fitting
On top of the blow off valve, it's delivered with an over-dimensioned 1/4" pneufit quick connect fitting for a 6mm hard tube. Used to connect the blow off valve to the inlet manifold vacuum. Additional tube and barb fittings are available as accessories.

 What is the purpose of a blow-off valve, and how does it work?
A blow off valve is actually a Pressure release valve that releases turbo pressure / boost when the throttle plate is closed. While the turbo is still spinning and creating pressure, a wave of pressure will travel back to the turbocharger when the throttle closes, this will results in that the compressor wheel stalls the “compressor surge” and slows it down very quickly.

 A blow off valve mounts in between the turbo and the throttle and is connected to the vacuum
 A well-dimensioned blow off valve increases the turbo´s lifespan and is necessary for its functionality

This is hard on the bearings and decreases the turbo´s lifespan, it will also take a longer time for the turbo compressor to spin up the next time the throttle opens and the turbo will not be able to deliver maximal boost as quickly as possible.
