WHISTLING TRUMPET -LOW BOOST-

Description

Whistling
Trumpet

You
asked, we delivered. Many
times we have been asked for a
replacement trumpet that gives
a different sound, and here it
is.

5702-image-1The
ability to change the sound of
a blow-off valve is
increasingly becoming an
important issue with buyers,
who want to sound different
from everyone else.

In
2004, GFB released the
Whistling Trumpet (part #
5701), which emitted a
piercing screech when driving
aggressively. Unfortunately
for a number of GFB owners,
the 5701 trumpet only worked
with some valve
types.

For the owners of
all other types of GFB valves,
we have now released the 5702
– a modified version of the
Whistling Trumpet that is
designed to work on low boost
applications where the 5701
doesn’t cut it.

The
5702 can be used in place of
the standard trumpet on all
GFB valves, and will make the
whistling sound more readily
than the 5701 (high boost and
RPM is required to get the
whistle from a 5701), and at a
slightly higher pitch. Like
the 5701 however, it is
necessary to run the valve so
that all (or most) of the air
vents through the trumpet –
Respons valves will typically
not generate the velocity
required to whistle when set
to 50/50
venting.

This
part is recommended for
Respons and Deceptor Pro II
valves EXCLUDING T9003 &
T9503
