How do you know when your turbo is out? Options

[mk7celica]

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?

If your gate is open you will get no spool.

Ok so if these cars with ceramic turbos and fmic need bovs why dont say reputable engines from reputable manufacturers use then in the past, like 1j, rb25, sr20, 4g63 etc. Cars with stock fmic and ceramic snails.

Im not denying they are a good thing to have (I have one) but i am saying it wont cause the death of your turbo unless your screwing heaps of boost out of it, which is going to put it under heaps of load in more conditions then just backing off.

metal shavings in the inlet cant come from the exhaust wheel, only the inlet.

Was there any noise prior to the lack of boost? Either you have a massive boost leak (unlikely), your wastegate is stuck open, or your ceramic wheel has fallen off/disintigrated, the latter is especially possible if you were winding the boost into it at the time.
