Do i have to run a DV

[har-vey]

hi all, i am new to the starlet scene and i have just picked up a very nice little Glanza off here. my question is do i have to run a dumpvalve? i prefer the chatter noise, is it possible for me to achieve this? i have a blitz dump valve and a fmic if that makes any difference

sorry for my ignorance

Is the blitz dv adjustable? Cld try adjusting it for more chatter?

U can just block it off tho it wont do any harm.

[har-vey]

i think it is. not sure how i would go about ajusting it though. would i want to tighten or loosen for more chatter and how would i go about blocking it off. just remove the dump valve completely? what would i do with the vacume hose?

[har-vey]

is there no negative effect of blocking it off? will it not increase wear on the turbo? slow down the boost process?

[Amjad]

It won't do any significant damage

[akyakapotter]

Will be fine chatter FTW

[Banbury Glanza]

Is that the same for any turbo as I'm running td04 ? Will it damage it if I run it with no dv

[AdamB]

Running without a DV isn't a problem, although on more expensive turbos like garrett,precision etc I personally would because it puts less strain on the bearings when air tries rushing back through the turbo and stalling the compressor.

[Banbury Glanza]

So in ok with the td04 then

[har-vey]

if the air passes back through the turbo and tries to stall it, will it not take longer to spool back up, thus creating more lag?

[J25GTi]

but the air in the pipe is already semi pressurised so shouldnt need to spool up as much

[Liam_D]

I run mine without a DV, ive just blocked off the vac pipe off. Mine chatters awesome for such low boost.

It wont do any damage its just a myth

[Banbury Glanza]

Glad that's ckeared up ...... DV coming off

[pick1]

Chatter ftw

The whole idea of running a BOV mate ;) They wern't invented to sound good, they were invented to do a job!

so in a word, yes. it is noticeably more laggy?

[Banbury Glanza]

So is its yes you can or no you can't lol

[Liam_D]

I have ran both with and without and theres no difference at all.

[AdamB]

Like I said, its ok to use on cheap shitty turbo's that are readily available, but I wouldn't want to be spending £700 replacing the CHRA on my garrett for the sake of not running a BOV.

It is noticeable different if your running higher boost setups, running a stock-mild setup you won't really notice anything other than a different noise.

They are there so that when you let off the throttle taking a bend, then get back on it again, the turbo is not stalling.
