Billet Blow-Off Valve
System
The
stock blow-off valve on GXP and RedLine is part of the
turbocharger itself, and its capacity is very limited,
especially on cars that have been modified for more
performance and airflow. This External Blow-Off Valve
System features our new
Adjustable Billet Blow-Off
Valve and is a direct fit, with all
needed components included. With this system, you can
now enjoy the benefits of an external blow-off valve’s
greater flow capacity and adjustability. As an
additional bonus, you also lay the foundation for a
turbocharger upgrade later, as larger upgrade
turbochargers require an external valve.
Why does my car need more blow-off airflow?
The
blow-off valve (also called Compressor Bypass Valve) on
your car creates a relief circuit for turbocharger
airflow anytime you suddenly close the throttle, such as
during upshifts. Without it, the airflow being produced
by the turbo would dead-head against the closed throttle
plate, dramatically decelerating the turbocharger and
causing poor boost response when you then re-open the
throttle in the next gear. Your stock valve is a
concession to economics of production and is very small;
its location in the turbocharger itself also suffers
from poor airflow. A larger external valve will keep
the turbo spooled up much better on upshift, and also
reduce stress on the turbocharger itself.
Why should I use an adjustable valve?
Every
driver has a slightly different shifting technique, and
different levels of modifications also create different
airflow levels for the blow-off valve to bypass. With
this system’s adjustability, you can fine-tune the
valve’s performance to suit your own particular driving
style and equipment combination. You’ll see greatly
improved upshift turbo response! The system also
provides a much more satisfying ‘whoosh’ than stock
valves.
