What BOV do you use ? ( blow of valve )

[venomous]

What blow of valve do you guys use on your supercharger / turbo setup?

Once i get my charger on i dont want to do anything with it unless i get a BOV because i read in a few places about pipes getting blown of and the reason being the user didnt have a bov.

i dont want to use the 20$ bosch one, so wich one can you reccomend ?? ( this is gonna be for a CRS style setup )

depends what type of supercharger setup your doing, if you want a BOV to work properly you need to move the throttle body pre supercharger to have a properly venting BOV.

yeah like i said im doing a CRS style setup and moving the throttle body, so what would be a good blow of valve for this, as in brand wise / size ?

If you move the throttle body infront of the charger then you wont need the BOV

but can i still use one ? i dont want it venting through the pod.

carn dude, you just want the sound, and so do i
i'm gunna use one of those low psi plumb bak/ vent to the atomosphere units, or just a plumb back.

you'll find a heap on ebay cheap generic brands, just make sure it's low psi and adjustable, cause 3 psi is really low

its not all about the sound, ive just seen alot of threads on other forums about plenums blowing of and pipes splitting, im on a budget hence the reason im doing a cheap 1ggze charger style setup, i cant afford to be replacing my engine, charger, and piping all the time lol.

PIC # 1
hey also, i drew a pic on how i THINK its meant to be setup, But for the first picture, wont you still need a BOV between the engine and the super charger?

Of you dont have one wont it just throw the excess air pressure into the engine and stuff something up?

PIC # 2

For this setup, where would the BOV be ? inbetween the charger and the T/B? or inbetween the T/B and the Engine ?

Picture 1 doesn't need a BOV, no air can get past the throttle body so no air will be compressed so you don't need one, it's just like a retro SC setup on a old big block street machine . In picture 2 you have it between the throttle body and the SC so that when you close the throttle and the SC is still boosting the air pressure can escape somewhere
