Bro i have broken the shaft :wavey: ... I once bought a Turbo that was choosen by Tong after i explained my engine specs to him ... I said that i was gonna boost a minimum of 2.5 ... I ended up boosting 2.7 daily driven ... He might have tought i was lying so he sold me this turbo and under estimated me ... i returned the turbo back in 1 month with shaft patah and fin gone ... because it spool backwards upon chirps ... :proud:
On daily drives i would use my SARD racing BOV (UFO type) ... for drags i would just replace the bov with a rubber stopper or battery so that i dont get any boost leak ... According to Tong ... that was the reason the shaft broke ... basically he thought i was BShitting all the way and never thought i was gonna boost that high ...
Just sharing my past experience ... Happy Boosting ... To every one ... if u change ur BOV and the sound is Turrr turrr ... better change to a different one ... its gonna spoil ur Turbo
...Hell its not even ur BOV sound ... its the sound of the turbo surge ... its good in a way there's no boost leak .. but it will slowly reduce the lifetime of ur turbo
... if boost below 0.5bar they maybe ok kut ...
Cheers
