my BOV froze shut today while i was at work, i was wondering how possably damageing this can be for the BOV and turbo, and if this is very common in cold places? today i think the high was like 10.. also is there anything i can do to help prevent it from feezeing shut?

and one more question what's the loudest BOV currently being produced?

 

Mine has frozen, but not completely shut, it just opened slow *** hell, it warmed up though as I drove. Greddy type S

 

Turbo XS RFL (really ****** loud)

 

same bov i have, the greddy type s, it froze completely shut and wouldnt open for about 20 minutes and by that time i was home just had to keep my foot off the gas cause i dont wanna expletive up this turbo till my new one gets here

 

Your kidding yourself if you think having no blow off valve is going to do anything to a turbo, especially if you have a new one on the way.

 

Hey try this... An oil based product will NOT freeze... So if you here to spray some WD-40 inside the BOV it wont stick close or even a small amount of oil on the actual piston... It will actually help the piston move alot better and slide with ease.....

compressor surge can mess up the turbo, i know my **** about turbos and the motor, i just havent delt with a frozen bov before

i've had a turbo sieze up because of compressor surge and haveing no bov

and i dont want to mess up this turbo because i plan to sell it, go give bad advice somewhere else

i had someone just tell me a bit ago what to use to keep it in good shape and keep from freezeing, i would have sprayed WD-40 but i dont want to spray something like that into it and have it going into my motor

im gonna unmount it and do what this other guy suggested and see how it works, thanks for the replys!

 

Not having a BOV isn't going to kill the turbo in any short period of time, there will be long term consequences however.

As for the WD40, the last thing that you want to spray into a boosted motor is something that is flammable. It can throw off your A/F ratio and/or combust agaist the timing.

 

Mine freezes when its real cold, a couple shots of WD frees her up though.

 

wd-40 should do- just dont go crazy with it.

oh... also, wd-40 is no longer made flammable

 

i've had a turbo go out in less the 6 months from compressor surge, im not takeing my chances

 

dont some stock porsches use no bov and have compressor surge and still manage to last quite a long time?

there's no way if faild from compressor surge. in all honesty...i've YET to see a turbo really fail due to compressor surge. I've seen them fail after 5 years on a car with no bov/bypass...but, that was mostly due to an oiling issue. lots of local domestics don't run bov's on their blow through setups....and have been since the late 80's turbo fad, and the majortiy are still running the same setups

 

thanks but i know what my own turbo died of, and yes it was compressor surge, so if you havent seen one, now you've at least heard of one

and i dont think its fair to compare a porsche turbo system to a home made turbo setup without a bov

i've heard from you, the single person saying they've ever had a shortterm failure due to compressor surge with no proof to back it up other than these words you've just typed.

on my list of ppl i give a **** about what they say....you're down there with George W. congrats.

 

go **** in someone else's nick of the woods dumbass, i couldnt give a **** if you care about anything i say, i didnt ask for opinions on why a turbo on a car i had over a year ago died, i asked how to keep a bov from freezeing shut

i know why my turbo died, i had a mechanic look at it and diagnose it, and i didnt feel like fixin it, so go give your snobish opinions and ******** insults somewhere else

 

haha....a mechanic told you it was compressor surge too huh. how'd he come up with that?

 

yes, a mechanic told me, why, does that confuse you? can a mechanic who specializes in building turbo setups not spot compressor surge? get off my thread and have a nice day, douche

 

my bov froze up and built a snowman and everything was fine.

lol.. what are the chances of having the whole can blow up?

very slim... you just got to remember to stop pressing when the flame gets too close to the nossle.

 

WD-40 or CRC works just fine. On piston BOV's you need to occasionally lube the piston up so that it works smoothly, you dont spray the WD-40 when the engine is running and it wont affect the AF ratio when you've applied it to the bov. You probably might wanna dismantle the bov to service it.

 

This is hilarious really...

WolfGod I think you need to upgrade your turbo from your SSAC piece of **** and buy a turbo who's plastic shaft won't snap from 100grams of air.

If you actually think about the opposite torques on the shaft during full boost, then compare that number to the relatively negligible torques upon the throttle shutting, I think you will realise that you and everyone else who think blow off valves do anything is a **** dick and is wasting their time.

Your turbo didn't die from having no blow off valve. No one has any proof of this concept for a reason; It is a myth.
