Default 2009 G8 GT AC Belt

I spit another AC belt off. I've already put a new Powerbond balancer/pulley and a new off brand tensioner and belt on it. Seems like it might be doing it when do a hard pass on the car and get the revs are high. I don't hear it come off and every time it happened it did at night where an immediate loss of AC would not apparent. I ordered a Delco Tensioner and a new Dayco belt today. Is this a common problem? any suggestions are welcome.

My G8 kept popping the AC belt so the dealer installed a double idler pulley upgrade that squeezes the belt into a figure 8 for better pulley engagement. The belt never came off after that so I highly recommend this factory upgrade.
