GT Dual BallBearing Turbo Question/BOV question
 

okay, so i hear this rumor. GT series turbo's that are Dual Ball Bearing does not require a bov? compressor surge does not hurt the turbo. is this true or no? im havin bov issues n i dont wanna run one lol. will this result in a garbage turbo or will i be okay. thanks

Re: GT Dual BallBearing Turbo Question/BOV question
 

BOV issues?

Re: GT Dual BallBearing Turbo Question/BOV question
 

<_< Ball bearing pretty much means there is less resistance for it to spin, thus a faster spool usually results from a ball-bering setup. Given that it still spins like any other non-BB turbo a BOV will do the same in both instances, which is preventing backflow back into the turbo.

Re: GT Dual BallBearing Turbo Question/BOV question
 

yes bov issues, im to poor to buy another real bov, ive been through 2 greddy type S bov's, 2 hks ssqv bov's, and an eclipse 1st gen crushed to hell lol. they all break or leak or some capola...


i dont care if it pushes the turbo ------ upside down n under its moms boobs. i jus wanna know if it causes damage in anyway. i dont care for compressor surge. i like compressor surge.

Re: GT Dual BallBearing Turbo Question/BOV question
 

I personally would run one.

Re: GT Dual BallBearing Turbo Question/BOV question
 

get a tial bov then, they are about the best ones you can get.

Re: GT Dual BallBearing Turbo Question/BOV question
 

Its true. it doesnt hurt them.

Re: GT Dual BallBearing Turbo Question/BOV question
 

couldnt it break the shaft after awhile?

Re: GT Dual BallBearing Turbo Question/BOV question
 

over hundreds of years just from stress like everything else.. so in otherwords not in our lifetime ;-)

Re: GT Dual BallBearing Turbo Question/BOV question
 

so i can run no bov with no worries? this would be great if its true

Re: GT Dual BallBearing Turbo Question/BOV question
 

theres no need, you won't hurt it.

Re: GT Dual BallBearing Turbo Question/BOV question
 

you have to make sure to get the anti-surge housing on them though....the most common are on the GT42R's

Re: GT Dual BallBearing Turbo Question/BOV question
 

sarcasm? i need a straight forward answer, im a retard.

Re: GT Dual BallBearing Turbo Question/BOV question
 

you still need a blow off valve. the only diference between ball bearing turbo's and reg bearing turbo's, is the spool time. But in regards to the blow off valve, yes you still need one. think about it, where is all the air going to go, when you close the t/b. Well is going to go back into the turbo, and past the seals at the same time it stops the turbo from spinning.

with the bov open when tb is closed, the turbo keeps spooling and will give you better boost for the next gear.

Re: GT Dual BallBearing Turbo Question/BOV question
 

how in the hell have you managed to have that many leaky bovs? ive never had one leak.

just go buy yourself a blitz DD, good strong bov wont let you down. Ive used blitz bov's on several setups

Re: GT Dual BallBearing Turbo Question/BOV question
 

I love my knockoff tial BOV.

Re: GT Dual BallBearing Turbo Question/BOV question
 

ur not boosting 20+psi?

my roommate has a blitz dd n it sounds boring. donald said so n so from roadrace says bov on gt series bb turbo = no need and causes no damage. wether it spins backwards or not, causes compressor surge but thats it, no internal life long damage ever. jus regular wear n tear over time. lets see what happens.

Re: GT Dual BallBearing Turbo Question/BOV question
 

you're either stupid, or have alot more money then me. I wouldnt risk trashing a garrett BB turbo just to "see what happens". It doesnt matter what the turbo is, a BOV will NEVER hurt, it will only help.

Re: GT Dual BallBearing Turbo Question/BOV question
 

no serious. there is no need to run a bov because the bb turbos aren't prone to compressor surge. the the shaft and bb can handle it but at the same time it never hurts and will prolong its life. its just not as big a deal as if the the turbo were not bb.

Re: GT Dual BallBearing Turbo Question/BOV question
 

im not stupid, n maybe i do have more money then you. either way a bov is hurting me in this case. maybe i should jus buy a tial bov? i can't hold consistant boost. its annoying. i watch he gauge jump to 20 drop to 13 jump back to 17 then hold at 15... i dont get it lol. then after like 3 strong pulls, the bov gets stuck or starts leaking cuz then it lags, goes from 7psi to 13 then holds at 14. then in 4th gear its only 10psi til redline, when i kno the wg is set to 20ish cuz b4 i started havin bov issues it held 20psi fine. after i sold that bov for what i thought was a better one is when i started havin problems.

Re: GT Dual BallBearing Turbo Question/BOV question
 

thats really weird. My uncrushed dsm valve holds 18psi, rock steady. Diesels dont have BOV's.... and they have non ball bearing turbos. Guess you dont need one either, but when your talking about a $2,000 turbo... id buy a tial

Re: GT Dual BallBearing Turbo Question/BOV question
 

stock dsm bovs usually flow just fine to prevent compressor surge. I dont think id try running without one on such an expensive turbo, i mean, compressor surge in general is damaging, just because the turbo survived it doesnt mean id like to have going into surge all the time, unless you like shaft play. Oh yeah, diesels dont have throttle plates either, when is the last time you heard a diesel surge?

Re: GT Dual BallBearing Turbo Question/BOV question
 

wtf Yes they do.

Re: GT Dual BallBearing Turbo Question/BOV question
 

Not the hundreds I've seen.

Desiels don't have Throttle Plates, Thus no need to discard the excess pressure smashing into the Compressor.

Re: GT Dual BallBearing Turbo Question/BOV question
 

ah :1

Re: GT Dual BallBearing Turbo Question/BOV question
 

Diesels surge, its just that since they dont have throttle plates there isnt as much of a violent stop for the air as if it had a throttle plate. I thought I remembered reading an article where garrett was developig an electronic BOV specifically for deisels.

If you listen when he lets off in this video you can har the compressor surge.

Re: GT Dual BallBearing Turbo Question/BOV question
 

LOOK if you want to be that much of a tight wod thats fine dont buy one
i have seen the shaft twisted but not broke! the blades hit the housing and fucked them up. i mean how could it not hurt somthing spinning that fast and not only stop but spin backwards?? but what ever buddy, getta rope

Re: GT Dual BallBearing Turbo Question/BOV question
 

end ur self, next question
