bov or no bov?

[s14jesse]

is it bad to run my SR with no BOV? i had it like that 4 a bit but i wasnt sure if thats safe or not
:wackit:

[Slidin240Wayz]

It's ok...........

[Future240]

some people swear by them, some people hate them, its really up to you

[Addicted2Kouki]

If youre gonna get one, recirculate it.

a blow off valve only prolongs the life of your turbo. if you don't care about your turbo then dont use a blow off valve. if you want to protect your investment, $150 is cheap insurance.

Couldnt have said it better.

im waiting for the "if you dont run a blowoff your turbo will spin backwards and explode comments"...

it wont be the reason your shit breaks - but its not necessarily "good" for it

well it could eventually lead to you shit breaking. it all depends on how strong the turbo like the condition of it. but surge isnt a good thing over long periods of time.

[!Zar!]

Meh, bov's are over rated.

I ran for ages without one and shit still worked.

[fbiphil]

I adjusted mine so it only opens at max boost- turbo stall sounds so much better than blowoff!
Engine feels more responsive, too- you're not dumping all of your boost every time you shift.
Of course, I'm waiting for my t25 to die so I can justify upgrading... so if this actually DOES shorten the life, so be it. I might not be so willing to take a chance when I have the new one on there!!

[!Zar!]

It takes a lot of abuse, and time for a t25 to die with no bov.

Anyways, you can get a t25 with every sunday paper now-a-days.

[smelly240]

for a long time i ran no bov - and never had a turbo break... and i dont run a sissy t25 @ 12psi :D

MAN if you dont run a blowoff your turbo will spin backwards and explode!!

[!Zar!]

I heard that if you don't run a blow off valve the turbo will stop spinning and then a black hole will form.

boy does that sounds so uneducated. it's like spreading a rumor among children. explode? some impeller fins might shoot off out of your tailpipe if you don't have a cat. other than that i feel all of possibilities have been covered. your choice man.

If you get impeller fins out your tailpipe you might have to wonder what kind of damage they did on the way through your motor.

[SoguRacing]

haha my bad i meant the little fins in the exhaust housing. :bowdown:
my bad

[DDDsquad_s13panda]

all it is is that u loss spool. due to the pressured air goin back to the turbo and slowing down ur spool.

i think its gonna take a long time to break. like everyone says. but that shit aint gonna BLOW UP.

[aNskY]

i never ran a bov on my stock sr's, never had a t25 blow either.

now that im running an upgraded turbo i run a bov because $150 < $1000+

vent to atmo without stalling too... djetro FTMFW!

[Z33dori]

yea i would be more worried about shitty waste gates than not having a bov....

[renegade_ewok]

Some motors in japan never came from the factory with a BOV. You'll be fine on stock boost

[Silverbullet]

uhh, all turbo motors from Nissan came with a BOV.

[Oo_Skyline_oO]

^^^ I beleive cefiro and/or laurels with RB20DET's come without BOV, my first motor came with an elbow without a bov.

here's a pic of one: http://www.flashoptions.com/i_prod/cefiro%20RB20%201.JPG (http://www.flashoptions.com/i_prod/cefiro%20RB20%201.JPG)

[nightshiftgarage]

im running a t67 with no bov.for drifts i ll probably make a peice of charge pipe that has one . but for street and drag no bov for me

[jskateborders]

That sounds like a good Idea... Plus, Ive been told that bb turbos dont suffer from compressor surge. Not my words, just figured Id throw that in there to get some feedback on that. Theoretically, it makes sense that bb turbos would deal with it better.

[racepar1]

BOV's are a good thing to have, but for god's sake get one that you can re-circulate back into the intake. I hate the BOV's that sound all "the fast and the furious"! OH, and adjust it correctly. It is super annoying when the BOV is always going off, especially with a HKS ssqv!

my 86 200sx with the factory ca18et doesnt have a bov. also doesnt have an intercooler. just a pipe going directly from the turbo to the throttlebody.

lol ... the only one i hate to hear is the Greddy Type S... most annoying sound in the world

idk my mom has a recirculated stock rx7 bov on her Z and its pretty noticeable at full boost out side of the car.

[bardabe]

Z31, had no BOV either, nor did CA18DET's you will be OK don't worry about it.
