I decided to drive my GTO today and do a little bit of calibration tweaking. It was all going great, so I turned up the boost a bit.

A few pulls, a few tweaks, and it felt fantastic… right up until it didn’t. The coupler on the intake side of the passenger side turbo was loose and it got sideways and then sucked into the compressor. It wasn’t obvious driving the car because the other turbo was able to make up for the difference in air ( these are GT3071s ). As soon as I got home and looked under the hood I saw the damage. Time for a new turbo. Drivers side turbo is of course fine.

It does look like a few small parts of the compressor wheel broke off, and I suspect those pieces might be stuck in the intercooler. Further investigation required.
