hey guys...call me a newb if you will but im new to the game and just have one kick question that im sure you guys will be able to answer in two seconds. On the following picture what is the small hole used for??? http://users.bigpond.net.au/Digital_Pimp/Turbo.html am very curious and am wondering does it have something to do with the wastegate or does is serve some other purpose...cheers guys

I think it's got to do something with the wastegate! What tubonetics turbo is that? And how much?

yes that is the wastegate hole. ur dumppipe , will have a small flap which will press up against it when closed. exactly the same as how the vl turbo wastegate and flap etc is setup.
