I gust got the greddy BOV and it seems to shutter no matter what the setting. Can anyone tell me how it is suppose to be installed on my 05 evo. Pics would help.

SeriouslY? or just playing?

Same orientation as stock. Put teflon tape on adjustment screw to prevent leaks. Leave lower nipple open, You can connect(T it into another pressure source if you want to help the bov open up quicker to release air. I had it working fine with one connection.

I think you need to lube the bov and play with the adjustment screw. You might have to play with the springs. 2 springs easy on the adjustment. 1 Thicker spring, less threads on screw.

Good luck

 

I've had the type s for a year now and it never sounded off correctly, it sounded like the stock at anything over 5psi, and it would sometimes compressor surge. I t'd off the boost controller line (turbo to boost controller) and hooked up a 1/8 in line from the t to the bottom port on the type s, and it sounded off perfectly even at high boost (top set screw is set to 6 threads). Also both springs are inside.

It was then leaking under boost, wouldn't hold over 15 and would taper down to 12. During a boost leak test it would open as well, so I took it apart (super easy just make sure you hold down the purple cap when removing the allen head bolts). I noticed that the diaphragm (black rubber piece) was ripped so I took some black rtv and coated the inside of the rip and the outside (the metal circle piece inside the diaphragm comes out). I let it dry for 24 hours (full cure time) then re-assembled it. I also cleaned/polished the inside of the bov and put a thin coat of oil on the shaft. Now it holds boost and sounds off perfectly!

To summarize:
1. T off the turbo to boost controller line and connect the lower port of the type s to the T.

2. Open the BOV and see if the diaphragm is ripped,
- you can try and repair it with

-or buy a new diaphragm for $80. http://www.shopgreddy.com/turbocharg...placement.html

3. Clean the inside of the bov

4. Reassemble the bov (keep both springs)

5. Try setting the adjustment screw to 6 threads sticking out from the top of the nut.
