i was carried up this inquiry last night by a friend, ns have world in my an ar that have actually BOV on there none turbo engines, how does the Bov get the earlier pressure indigenous a no turbo come still make the ptshhhhhhhhhh sound of a turbo v one. Is it good to have one on a no turbo car, does it influence the engine, is that bad. Please aid . Any type of comments space welcome. Just so I deserve to put my friend straight. He cd driver a small Geo Storm therefore go simple on the

Your friends room retards. Correctly it will make a an extremely faint psssssssshhhhh sound on a NA car. Yet damn that"s therefore ricey. Tell lock there"s a fake BOV out there and there"s likewise a plastic intercooler and they can additionally the those ractive mufflers that have a turbine right before the guideline so it can have that turbine spooling v the exhaust sound.
Where walk the BOV obtain the press from a non turbo automobile to make the pass out psssssshhhhht sound..............

The BOV opens up at vacuum, so when they let turn off the trottle whatever air is in the intake pipe will discover an easy way out through the BOV and make a very faint sound.

no no really.. Yes sir no way enough push could construct up.. Hardly any type of pressure builds up because it simply stops .. There isnt anything still shoving air towards the throttle body.. The impossible.. No to cite ###..

tell ur friends who have actually bovs on their n/a cars the they are true def. The rice boys.. And tel em to take it it off reason its bad for their car.. Heh.. We have actually bovs because that a reason.. Cause we have the turbo
*

Rice my girlfriend is no the word exactly how does he setup on backing increase the PSSSSSSHHHHHTT sound that is car make as soon as the motor come barley the end of vacuum
*

hahah nice pic.. Its negative enough the they room ricey.. Yet when they understand it and still practice riceism.. Thats crazy!
I agree..I dont see how theres any method there"s sufficient vaccum to open a bov, and enough press to make a noise....If it still makes a psssht noise, look because that an alert looking speak horn, thats the source of the noise.
if you installed a yes, really soft feather on the wrong next of the piston... You might make the close under atmospheric conditions... And also open under vacuum... And then as soon as you... Ummm...why space we doing this again?

One of my friends want me to examine why his auto wasn"t structure no an increase at all (97 lude v drag kit). So after driving around a little I was encouraged that there to be a massive boost leak somewhere due to the fact that I can still listen the BOV. After inspecting the pipes I found that one ar was fully disconneced. There was around 2-3 inches separation native the one finish of the pipeline to the other, no method the intake could be pressurized however you could still hear the BOV. A quick standstill rev and also i placed the hand versus the outlet that the BOV and also I might feel wait comming the end (blitz SS). Later on the turbo to be leaking oil right into the compressor housing. The turbo to be toast because of driving tough with disconnected pipes.
If you"re hearing something indigenous an NT BOV, it"s only going to it is in manifold vacuum bypassing the wait filter, illustration air straight right into the plenum. Other than backfiring, the input of a non-supercharged engine won"t have any pressure come vent. Has actually he looked into gaining a wolf Whistle from JC Whitney and also putting the under the hood?Of course, the PSSSSSHHH could be the ECU screaming ??? in its very own native maker code....

Then have the right to i ask this question, the cotter pen the host the wastegate aquatator pole to mine exhuast manifold broke so the stick vibrated of and i shed all rise because the wastegate to be stuck open yet my an increase gauge still read 1-2 psi v a slight hiss native the bov between shifts so might there it is in a hiss on a no turbo car? now rember atmosphereic pressure on typical is 14-15 psi

true but.. Her guage mirroring 1-2psi is 1-2 psi over atmospheric pressure(isnt it?).. Ns dont check out a BOV makin a noise at every on a NA uneven you take it the spring the end .. PLEASE....SHUT....THIS....THREAD....phew! to much rice because that me to handle..

He has a Geo storm, ns am the one that is gonna have actually the eclipse and I wanna be certain I dont make the mistake. So every you guys have actually helped me the end a lot.
