How do you know when your turbo is out? Options

This weekend I installed a new mbc and I had it set to stock boost at first then I raised it to 14lbs. I forgot to tighten a clamp for the coupler on the turbo going to my fmic. Well the engine killed I pulled over and put it back on tightened it and drove home. I decided to go for a test ride and I was in 2nd gear building boost got to about 12lbs and I heard a woosh of air like the intercooler pipe popped off again so I pulled over checked it and all other clamp an they all was on and tight. So I started to drive again and noticed my turbo was not making and sound and I was not building no voost. The car is like a n/a engine now less power no boost and the turbo lines,couplers ect are on and tight. I kind of hear a low clanking noise in the turbo I think. Is my turbo bad? Car runs and starts fine just have no boost and no sound from my ct26? whats the deal?

wow thats a big no no...you cant run it without a bov especially when your turning up the boost.....the bov is there to release all that excess air that your turbo had spooled up....when you release the acceleration it closes up the throttle and the excess air is pushed out of your bov.....thats your problem.... since you took it off....where do you think all that air went??.....yes to your turbo....and thats why your intercooler piping keeps coming off.....dude i think your turbo is done...you shouldnt have tooken off your bov....
