GReddy
Blow
Off
Valves
are
easily
adjustable
to
eliminate
compressor
surge
and
preventing
premature
boost
leakage,
while
increasing
boost
response
between
shifts.
Each
valve
is
made
of
durable
cast
and
billet
aluminum
frame
and
the
valve
to
diaphragm
ratio
provides
performance
that
cheap
piston
types
cannot
offer.
The
spring
stiffness
adjustment
screw
and
the
three
different
sizes
give
the
GReddy
user
the
option
to
match
vehicles
with
mild
upgrades
to
heavily
tuned
engines.
There
are
many
factors
in
matching
a
blow-off
valve
to
an
application,
valve
location,
turbocharger
size
and
pressure,
but
as
a
general
rule
of
thumb,
we
recommend
the
Type
RZ
for
100-400hp,
Type
R
for
260-460hp
and
the
Stiff
Spring
Type
R
for
over
400hp
applications.
