i have heard alot of talk about bypass valves but nobody ever told me what it dose...someone told me it is the bov for a supercharger and others said it is to block water from comming into the engine through the cai intake...help...if it is a supercharger bov thats sweet...if anyone has one get me a vid or sound file please!

 

it diver4ts the air from the sc so you dont get boost while idling. kind of like a bov but not really

 

will it make a distinkt noise after each shift like a bov dose?

 

There are no "Blow off Valves" for our supercharger.

There are blow off valves for non roots style superchargers.

In most supercharger cases, a blow off valve would not benefit in any way.

 

so i cant even get the noise for my ss s/c?

 

yeah..sure...you can buy one of those fake electric BOV noisemaking POS off ebay

 

the only noise is the whine the sc makes, nothing else

 

no i want like the real thing like a distinkt noise after each switch of gears comming from my engine not from an electronic box

 

so then what dose the bypass valve do becides put ur boost from zero boost when ideling? dose it put it into negitave boost? what dose it do exactly i am new at this

 

all the bbv does is divert air from the sc so you dont boost at idle.... thats it.... nothing more. no you cant get a sound from your roots style blower.

 

what do u mean "roots style blower"?

 

roots style is the type of supercharger you have. the most common roots blower is the eaton.

 

if i were to change my supercharger would i b able to get a noise from a bbv?

 

There is a lot of info go do some surching and you will find all the info you need to know from some previous threads. I saw one a wile back that had a see through SLJ and showed the bypassvale.

I think the only was you can get that sound is if you go twin charged. Meaning if you put on a turbo that boosts after the SC is done boosting.

 

so do u think it is worth the $250 eaton is asking for their bypass valve just so u dont boost as much when idling?

 

you already have a bbv stock.....

 

is the aftermarket one any dif?

 

no...

 

wow.......might be new but research your car....thats what the search button is for

 

The boost bypass vavle is cast into the Eaton supercharger. You are going to swap it in and out, it's not a seperate part.

 

if you want the Distinct noise, get that rice box. the electronic one. Or trade you balt in for a neon or another car with a turbo.
