• 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 blowoff valve to the mounting flange using the supplied vband 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 vband 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.
