•Description: This blow off valve is designed to allow boost pressure to be bled from the intake piping on throttle off, while
in boost. Bleeding off boost pressure keeps turbocharger speed up during shifts which reduces turbo boost lag. This also
protects the turbo from surging when the throttle is closed suddenly.
•
NOTE: This kit requires cutting and welding. If you are not experienced with fabrication and welding, you should have
this installation performed by a professional.
1. The blow-off valve should be located between the turbo
compressor outlet, and the throttle body.
2. Select either the steel or aluminum mounting flange,
depending on whether your intake plumbing is steel or
aluminum. Mark the area where the flange will be
attached, cut the piping to accept the flange, and weld
the flange to the piping. After welding the mounting
flange to your compressor plumbing, and allowing the
materials to cool sufficiently, you may attach the blow-
off valve to the mounting flange using the supplied v-
band clamp and o-ring.
3. The easiest way to attach the blow off valve is to
remove the allen bolt and threaded sleeves from the v-
band clamp
(See Fig. 1) . You will then be able to
stretch the v-band clamp over the flange. Allow the
clamp to slip completely over the flange
(See Fig. 2) .

5. Now you may install the allen bolt and threaded sleeves
into the clamp. You may need to squeeze the clamp
together by hand to get the bolt to reach all the way
across. When installing the threaded sleeves, make
sure the sleeve with the machined area faces towards
the head of the allen bolt
(See Fig. 5) . Tighten the
clamp using an allen wrench.
6. Attach the supplied banjo fitting using the supplied
banjo bolt, and using one sealing washer on each side
of the fitting
(See Fig. 6) . Adjust the banjo to the
desired direction and tighten the banjo bolt. Use a 1/4”
hose (not supplied) and connect the banjo fitting to a
vacuum source. A 1/4” x 1/8” NPT (minimum) fitting on
the intake manifold is the preferred source. If this is not
available, tee into a vacuum hose that is larger than
1/4”, such as the power brake booster line.

O-Ring
4. Now place the o-ring into position around the receiver
groove of the mounting flange (See Fig. 3) . Place the
blow off valve over the o-ring and press until flush with
the flange (See Fig. 4) . Position the clamp over the
blow off valve and flange. If your blow off valve is not
mounted vertically, you may need assistance to hold it
in place while positioning the clamp.
