| Depends what kind of supercharger and how its set up. Need more info. Its not one of those things where you say, "gee, I want a cool BOV sound so I'll see if I can use one with my supercharger". Its more of a technical requirement depending on the system. If you want the noise buy an exhaust whistle, if you need one for your engine to run safely it would already have one. |

| why? Most blowers will dump boost without any major noise, but I've seen some set ups online where they've stuck in a BOV just cuz they could, it doesn't add anything. If you want to make BOV sounds just by one of those ricer BOV sound makers. :lol: |

| dude u could add a bov to an NA setup and it would make the noise....just no point. |

Step 1 - turn your baseball cap around so the bill is in the front.
Step 2 - never refer to anything as "gangster". :bthumbup:
Steps 3 to 147 available on an installment payment plan. :p |

Well first off you guys all know that you dont need a blowoff or bypass on a roots or twin screw type blower Kenne Belle, Jackson Racing, Eaton. You DO need on on a centrifugal (Vortech, Paxton, Procharger, Powerdyne etc). How do I know this? because I have one. All a blow off, or bypass does is divert the air when you close the throttle blades, while in boost. Make sense? You can either vent to atmosphere or back into the system. All of this depends on you air metering. If your airflow sensor is on the high pressure side ( Between blower/turbo) and the TB, then you dont need to recirculate because the air hasnt been metered yet. Now on some supercharger applications the air is metered BEFORE entering the blower, so any air bypassed has to be recirculated because it has been metered.
Clear like mud ? |

Also depends on where your throttle body is located in relationship to the charger.
If your throttle body sits before the charger, no vent is needed (charger gets no air to compress with TB closed).
If your throttle body sits AFTER the charger, you'll need a blow off valve or cycling valve, depending on if you have a MAF/AFM metering setup (need cyling), or a MAP metering setup (bov or cycling both works). |

| where the hell would you put a BOV on an NA? wouldnt you not really hear any sound cause their is not alot of pressure? |

| im confused..:blink: i saw a camaro on tv. with a supercharger and it had a blow off. it sounded kinda gimpy tho, like a dog whistle lol. maybe i need to cut back on the rocks lol. |

A common way to supercharge camaros are with a centerfugal supercharger; ALA Vortec, ATI Procharger, paxton.. that dog whistle is the sign of a decent sized blower :)
Think of those kinds of superchargers as "belt driven turbos", because other than that, there is no difference.

| ok thanks for the clarification:bthumbup: |

You need boost pressure in order to create the PSHHHHHHH sounds you get when your turbo spools up and releases the pressure.
It cant be done on an NA :blink: |

| mister_tu |
you can get a BOV on NA cars
just everytime u step on the gas it sounds off
so it sounds so dumb ahah |
|

| I dunno someone thought my civic had a blow off vavle? And i am N/A so i guess its how your car sounds to certain people. Basically if you want a BOV , just get turbo or supercharger and run at low psi and get the sound that way? i dunno i would only want a bov if i had extra power otherwisepeople would be like jeez he is a slow mofo if u have a bov with no extra power? |

Stop it! There won't be any BOV noise on an N/A. If you don't understand how it works... don't chime in. |

Some people just never fricken listen. |

| Or some people dont understand wut the noise is, like what i said, i had 2 kids come to me and belike omfg nice BOV noise i was like ??? Its N/A nothin else no BoV the guy is l,ike how u get the noise? I dunno some peoiple are dumb |

do you even know the purpose of it ? any boost level should have a BOV or some sort of bypass ... |

actually he's right buddy, there can be the BOV NOISE on an n/a car
they sell em on ebay,
http://cgi.ebay.com/ebaymotors/ws/e...sspagename=WDVW
i'm pretty sure that's what he's talking about |
|

| SketchifisT |
Yes i know the purpose of a BOV, but think about it? You want everyone to belike omfg he has a turbo he is quick and get smoked ?
I dunno thats just my opinion i wouldn't want to have a BOV just for the sake of a BOV i would want to have the sound cause i had the extra HP. Personally preference i guess |
|

| JustinL |
Scooby- That may be what he meant... but that's not what he said.
Sket- Are you saying that you would rather have a slower car that risks compressor damage on every shift than have a BOV? ...Unless you meant that you would rather have a CBV than a BOV because it would be quieter and and still serve the same purpose. |
|
|
| SketchifisT |
| /nod thats what i ment. Either way i prefer a tuned N/A over turbo atm ;) |

some people dont listen? check yourself.
told u they have them for NA
obviously there fake though but they do have them. |

It's still not a fucking blowoff valve ... its a fucking speaker. Get a clue. |

same place where it always goes. there is a pressure change (a way smaller one) in the intake piping when u let off really quick. its the same way a turbo car can still vent when revved in neutral. |

| JustinL |
| Jeff, Can you explain where this pressure comes from? To vent anything the pressure pre-bov has to be above atmospheric pressure. |
