boost pipe jumping off cause turbo shaft to bend
Can a boost pipe jumping off cause a turbo to over speed and bending the shaft?

imo, yes. as the turbo can easily overspeed. especially so if @ full chat. Generally you'll have a few blades bend before a shaft bending.... recheck to see if a few blades are bent over.
however, i have had a few pipes blow off & have never encountered a bent shaft or blades bending over.

Usually if the pipe blows off completely it will not hurt the turbo because the engine is not seeing the large amount of air which would feed the turbo the exhaust to overspeed it.
Now a car with a significant boost leak but not a total disconnect would allow the engine to get a lot of air and overspeed the turbo. Typically though overspeed will kill a bearing section before breaking a shaft.
If the shaft is bent or broken I would suspect compressor surge which can cause the turbo to suddenly stop or reverse rotation even with exhaust pushing on the turbine side. It could also be overheated and have caused fatigue on the shaft. Excessively high EGT's can kill a turbo fairly easily.

I do use the Norma T Bolt clamps...
It was a problem with the intercooler...long story...fixed it up.
But my turbo packed up and now they say it is because of a boost leak or pipes jumping off... never had leaks... just pipes jumping of at 29psi. 1200miles only and the HTA turbo was toast...
I have a sti9 with a GT35r and it had a major boost leak... for 3000miles... fixed and still running great with the same turbo

What is a "normal t-bolt clamp" ? Are you referring to the factory warm clamps or an actual t-bolt clamp?
If your using t-bolt camps with beaded intercooler pipes and your still popping off the pipes, then you might have oily residue that causes the couplings to slip off. I'd take it off and clean then with brake clean.
I had an issue with the coupler popping off the throttle body a while ago. It was because when I did my first clutch job a friend of mine used a little WD40 because we didnt have silicone spray to help slip on the coupling. Well that WD40 held its promise of keeping this slippery even with the t-bolts clamped to the point of almost breaking or cracking the TB inlet. I just used Brake Clean to wipe it clean and never had issues with it again.
Although you might not have sprayed anything oily on it, many people still run their pcv's recirculated and oil vapors will do the trick. Especially if you remove and reinstall a pipe that will break the original seal.
Hope this helps you.
