Would anyone happen to know how to install a Greddy Type-S BPV?

I has two nipples but my stock BOV only has 1 nipple so I'm unsure where the 2nd one would be connected to, attached is a pic of the BPV

 

heres the pic

 

little nervous for you... however, too nipples is normal...i'd worry if you only had one....as far as your bov use the top nipple...not the lower angled one...
make sure the bov is in the correct position...bottom of bov to charge pipe and front to recirculate back into intake tract. lmk if u got any more Q's

 

i fyou wanna use both nipples get hte dejon tools leak stop kit.

 

thanks for the pic, my attachment didnt work for some reason

why would I want to use both nipples?

 

cuz you can hold all the boost you can throw at it and vent as easy as pie.

the greddy type s is the only bov that is presetup to do this. hence why in my opinion it is the best valve made. of course i run a modified 1g dsm valve that does the same thing.

basically what the dejon tools leak stop kit is, is ia pnumatic switch. on boost it redirects all air up to the top of the diaphram closing it tight.

off boost it punches air under the diaphram to open it (bottom nipple).

case closed

 

You can just plug the bottom one. If you have any surging issues, connect the bottom one to a boost source to help blow it open.

 

VERY GOOD, boost source... not vac source... say no to the single spring mod.

 

hmm, I think my BOV has the single spring mod, going to have to check with the previous owner

 

ok it looks like I do in fact have the single spring mod so I dont need the leak stop fix and I dont need to connect the lower nipple to boost source

just a simple cap on the lower nipple and that should be it right?

would it be worth while getting the spring that was in there and using the leak stop fix?

 

my car runs great with the single spring adjusted.

 

When i had that valve i used the single spring mod and left the bottom nipple open. Held boost great and had no drivability issues.

 

see that's the thing... it may work for some... but it also may not work for others. it was not the way the valve was meant to be run.
