Did i blow my turbos?
So... today around 3rd WOT, i hear about a 1 second noise that sounds like a complete release of pressure... ???? help?
I'm immediately expecting the worse but i'm hoping for something less...
my boost gause for sure stops right before it starts to press... and of course the car feels like it has about 100rwhp. Pretty much like my Nissan pickup!
any directions to a previous thread or experience would be much appreciated!

most likely you just blew a hose or coupler just look around till you find it....don't continue to drive the car as you can over rev the turbo's if they have no back pressure.

Start at turbos and go through the system until you hit the throttle body. The stock system only has, what 3 couplers to check? It's not a big deal. You have to physically pull them off and check them for splits.
Another likely culprit would be the hose for the BOV. This is a 1" hose coming off the y-pipe and running to the BOV at the passenger side of the intake box.

OK, look at the below picture. See the black box thing in the centre of the picture? (2 blue lines coming out of the right side of it)
Scan directly left of this. You see the blue pipe with the white glove shoved in it? This is your Y pipe outlet. You need to check every single coupler from this point round to where the throttle cable attatches and make sure it hasnt popped off, ripped open, got a hole in bla bla. FYI - you will be checking that coupler, the plastic crossoverpipe that runs across the top of the engine and then down to the bottom hose of the intercooler, then the pipe that runs out of the top of the IC, and onto the intake elbow. Alot of this stuff is rubber, and old, and splits.
If you cant get to something, dont be afraid to take it off. Just make sure you dont let any crap drop into the pipes and put it back as it was and your car will be fine. These hoses all need to be done up pretty tight.
Access might be a bit difficult if you still have the stock airbox. If you do, you can remove that - its pretty easy. 4 bolts and then unclip all the hoses to the back of it - same deal for these, make sure you dont drop any crap into them (plugging them with gloves like i have there is a good way to stop this) and put it back as you found it.

If your system is stock then you have a coupling from the y-pipe to the cross over, one on each end of the s-pipe pieces (inter cooler to cross over pipe), And one from the throttle body pipe to the inter cooler. To check them remove them and if you like turn them inside out, if it splits (or already is) then it's bad ( too hard and brittle) you'll for sure find the split using this method (or determine the coupling has reached the end of it's usefulness) if a split doesn't turn up then it should be obvious where it seperated from the hose clamp.
