Anyone know at what PSI a typical plastic soda bottle explodes?

I've built a home carbonation system. The gauges say I've put in 150PSI of
C02 into the Trader Joe's (admittedly thick) carbonated water bottles.

Nothing happened (with respect to explosions).

Yet, as I dig on the web, I find that plastic soda bottles are supposed to
explode at 120 to 150psi.

Obviously I need more data.

Do you have data points showing when soda bottles explode?

PS: If there's a soda or carbon dioxide related newsgroup for home
carbonation, please let me know.

Be careful you know they don't check them all, only a significantly large statistically relevant sample. A bad batch of plastic and not all the defectives may be removed be fore shipping.
