Recirculating BOV and other BOV Question

[sepulchral]

I have a Greddy TYPE S BOV, would it be helpful or harmful to recirculate taht into the "normally blocked off hose" from the intake piping?

If helpful how?
If harmful how?

Also i have a nipple on my BOV thats not being used, what is it for?

[Gladman]

The extra nipple on the BOV is for quick release, it will make the BOV louder and open for longer.... if you're venting to the atmosphere you dont want that.

I would highly recommend you recirculate the BOV though, i had a type-s on my car for about 2 weeks and replaced it with something more practical i could recirculate, instant kick in power when i recirced.

[sepulchral]

Does that extra nipple connect to something?

If i find a hose that can recirculate the type s will it work fine?

wat did you use that was more practical?

IS there any noise to a recirculated atmospheric BoV?

Thank you

if you have a cone filter.. you can still hear it
i have a turbo XS open bov (atmospheric) right now.. it keeps stalling the motor and im running crazy rich because of that...
im gonna make myself a custom intake pipe with a bung welded on it to recirculate mine this weekend.

You can recirculate a type-s just fine, however, it sort of defeats the purpose of having a $150 bov. You probably wont be able to hear it nearly as loud anymore.

I just switched to a 1G talon bov, cost me about $20. Makes almost no noise, instead of BOV noise, i switched to external wastegate.

Wont make a difference, the recirc tube will soak up 90% of the sound, the rest will be drowned out by the MAF and filter, my bov was loud when dumped out, now you cant even hear it.

[sepulchral]

anyone have a picture of the tube u'd recirculate to? its after t he MAFS right?

[Bbandit]

its after the mafs.. as close as possible to the turbo compressor

[Gladman]

you can see the clear braded tube going from my BOV to intake. -

That tube is huge :eek3: lol, but I guess if it works! What type is of BOV is that anyway?

EDIT: thats greddy bov isn't it?

[s13conv]

That's a clean looking KA24E-T setup.
It looks like it might be a 1g DSM BOV.


I have the greddy type-s recirculated on my galant VR-4. It's on there because the DSM one can leak at higher psi. Sometimes crushing it can help it seal better. Dejon tool also has a kit that's supposed to help. With it recirculated I can hear it plenty!

single cam turbo :rawk: that the way to go..i wish i had the patience to do it

[scruffy63]

hey gladman what kind of exhaust manifold is that?

Whats the pros and cons of BOV location??? I got my sr20 installed at a shop and they put my BOV (Greddy type S) on the hot pipe! I noticed that you have your BOV right before your intake manifold! Does it really matter where the BOV is situated?

[nrg]

some have said that putting the bov on the cold pipe has better responds somewhere. Maybe it helps the turbo better. I dunno..
On s13, the OEM location is on the hotpipe or before the intercooler.
S14/S15 the oem location is on the cold pipe after the intercooler.

[evilimport]

I've heard its better on the cold pipe because the air doesnt have to travel back through the intercooler when the throttle plate closes....dunno for sure though.

Im not trying to pick a fight or anything but, dont we use a BOV to get ride of the pressurized air so that it doesnt come back into the turbo and damage it? So wouldnt it be better to have it on the hot pipe? so that the air closer to the turbo leaves quicker? :rolleyes:

i've had me type s venting to atmos. for like a year now and it runs fine,



12.9 @ 108 stock turbo on stock steelies

[Big Perm]

I recirc'd my type s and has made all the difference in a drivable car - granted I have only put 2750 miles in 1 year since my swap

thats weird cause i hear people saying that an atmospheric BOV makes your car stall and run rich and not run right, I run at 13 psi and have a greddy type s and isnt recirculated, and i dont seem to have any problems other then running rich!

[timmybgood]

i've put about 3000 miles on my car since my swap with an atmospheric greddy type-s, it has never caused any stumbling or stalling. i get great milage, but my nose tells me it does seem a tad rich...
