i may be purchasing a greddy type S bov from a member here soon and i had a question.

If i have the bov on a hard pipe near the fender, and instead of venting to atmosphere and rather recirculate to the accordian pipe....will this be too far away to recirculate? Or would that recirculated air just be enough to keep me from stalling and running really rich.

I hope my question makes sense.

i dont get what your asking but you should recirculate it and just as long as you get a long enough hose, you can put it anywhere on your ic piping just as long as your hose is long enough to reach back to teh acd. pipe

as long as it's plumbed correctly, you shouldnt have a problem.
i was recently looking at an audi w/a built 20valve that was running at the local dragstrip. he had a bypass valve recirculating, but it was on the other side of the engine bay... he had a pretty long piece of samco silicone flexible hose connecting it to the intake... i mean like 3 feet... so i dont believe you will have a problem.

you have to tune properly so you don't stall :)

:werd:

you have to adjust the thing. if its adjusted the right way the car wont stall, it MAY stumble a little SOMETIMES but it really isnt a big deal, at all.

Venting is overrated. If you tighten down the Type S as much as you can, you dont have to worry about stalling and you get the louder BOV capabilities.

However, my BOV is stripped and its as loose as a whore's vagina, so much that I have to engine brake everywhere I go unless the vacuum doesnt go up or down too drastically.

thats a horrible idea. its possible that at its tightest setting it MIGHT be ok.........

except if you over tighten it it wont function correctly, and eventually kill your turbo.

so again i say, you have to ADJUST IT FOR YOUR CAR.

you want to make it tight enough that your car dosnt stall out, but not so tight that you get that fluttering sound (turbo death).

its like a squelch on a walkie talkie!

Venting to atmosphere is pushing metered air from the system. It makes you run pig rich.

I have both a ssqv to atmosphere and a bosch recirculating. When I take out the recirc the car is crap to shift.

If you want to go pure atmosphere for the "cool sound", go with a blow-thru MAF and vent upstream of the MAF. Then the problem will be gone.

It makes you run pig rich.

only for that half a second inbetween shifts.

you guys are making a bigger deal of this than it is. if you want to recirc? sure theres nothing wrong with that. if you want to vent to atmosphere? there is nothing wrong with that either. if your BOV is properly adjusted you will have no problems.
