so when people say they have a dose pipe on that is what are running, whats in the picture above?
Ive been doing abit of reading on flutter/dosing and everywhere keeps saying how bad it is for the turbo? Is this true does flutter really stuff your turbo? Since ive installed the typhoon intake into the airbox my xr6 turbo doses fairly easy and why is this happening on a stock car if its bad for it? could my BOV be blocked? |

The sound your hearing is NOT "dosing". Dosing is caused by not having a BOV and the air coming back through the turbo getting "chopped up" by the compressor, giving a tuuu tuu tu tu noise.. What your hearing is just the BOV venting, but becuase your air box is now more opened up from the F6 intake the noise is not as muffled.. this i what dosing sounds like http://www.youtube.com/watch?v=ChfCSfeD1Ps

ohhk yeh what im hearing deffinantly isnt as loud as that and its not as drawn out out as that noise is.
The only reason i thought it was flutter is cuz its not a real quick woosh. But if its just the BOV no reason for alarm. Just didnt want flutter cuz im not interested in wearing out the bearings in my turbo for the sake of abit of noise |

I am getting a "tuuu tuu tu" noise, albeit far more subdued. From what I know, and that isn't much, the BOV only blows off so much, what's left flows back through the turbo, hence the flutter/dose noise.

But isnt that air flowing back thru the turbos really really bad?
becuase its the turbine blades chopping the air and ive heard that kills turbos I did ask simon at nizpro bout this very issue tho and he said thats a s**t myth |

Bar an F6 air box, mine is completely stock and it flutters, however since putting the new air box in, I've noticed it's a lot louder and now flutters at low boost.

Check the vacuum hose off the bov that goes to your inlet. It sometimes can be loose and will leak. This causes the bov to stay shut on low rev low boost and will not vent giving you the flutter you hear.
If you don't want it to flutter make sure the hose is clamped tight to the bov and the nipple on the inlet. Compressor surge doesn't hurt the turbo. Its been debated for years and there is no proof of it. The most common cause of turbo death is oil starvation and improper cool down. Dosing FTMFW! |
