Iv heard that atmospheric BOVs are not so healthy to the turbo and the best option is the stock wastegate.

What do u guys think ?

wastegate and and blow off valve's are two different things, also do different things, so i dnt get ur point here, i think what u saying is VTA ( vent to atmosphear ) blowoff vales are bad for the turbo and stock ones are better, well non is bad for the turbo but when the VTA relese the presure out Airflow circulation will different and u might get bad AFR at shifting

wat do u mean by boost leak bro? dey r meant to release the excess air dat is sucked in through the turbo wich accumulates once the accellarator is released.. so the stock valve does d same thing. d BOV i got is by AutoGauge with an adjuster for high and low..

got it from Motorcade in colmb. Emsees doesnt hav any.. Chek the FB group 'Kandy Racing Club' images.. got many performance upgrade stuffs..

btw ive got a Ej20 Twin Turbo engine wit auto gbox with AWD drive train front and rear. radiator and complete exhaust pipe as well. lemme knw if anyone's interested. also hav a set of Bilstein shocks..

leak means either BOV open early or not open at all, we had few issues in on of my friends RX7 with these Fake HKS look like BOV, when the BOV close there is a rubber seal like thing to make sure it stays close, but with the fake BOV's what happen is even the BOV is close still it leaks boost from the rubber seal area,

Stock Valve release the Air in to the intake and After market VTA;s release to the atmosphere, do a little bit reserch about VTA vs Recirculation and see, btw im also ruing a VTA but branded

ya i knw wat u mean. wen i set d valve 2 soft, i hear d squeal wen i gas up.. dont hav 2 rev hard.. cn hear a continous squeal as long as i keep my foot on d pedal 75% downwards... dats early releasing of the BOV. wen its set 2 hard den i hav 2 rev hard n let go quick so as so hear d swoosh!..

but still no sign of any leaks in idle n all. d spring is rely hard so doesnt tend to leak. craftmanship looks good though..

is it normal if i take my foot off the throttle quicker BOV makes a spiral like sound? :speechless-smiley-019: ... and if i do it slower it makes the normal smooth sound..

What exactly do u mean spiral sound ?

The final conclusion of this thread was that a after mkt BOV did not have any great advantages other than the noise against the stock BOV. So mine is still stock so there is not much noise.
