The TurboXS Blow Off Valve - Type S 
is designed to release compressor pressure surge caused by changing gears or
backing off the throttle quickly. This valve is an extremely important
part of any turbo system allowing quicker turbo spool up between gear changes
and greatly increasing the life of a turbocharger. The BOV Type S is recommended
for small to medium sized turbo charged engines running 12 psi boost or less.
For custom turbo applications, the TurboXS Blow Off Valve Type S is installed directly into the connecting pipe running between the turbo and the throttle body housing as shown in the diagram at the right of the screen.

The valve vents to atmosphere at sound pressure levels in excess of 106 dB when measured 3 feet from the valve.
The unit is fully adjustable by adding adjusting packer washers included with the kit. The high grade aircraft aluminum body is anodized bright purple to provide outstanding looks and superior corrosion resistance.
