We talked and he said it's the older design, and they are known for having the stub shafts break. Given the damage, and the $1000 cost for a new cartridge, I don't plan to fix it out of my pocket.

True, like if I had broken something and material went through the engine, it could wreak havoc on the turbo. I know of someone who lost a few turbos that way one weekend.
In the end it looks like the issue is the turbo not taking the power. Thanks guys.

Well it makes sense, everytime I tried to run big boost I broke it, both times.
Oh well life moves on, I have an LSX block here and 6 bolt TFS heads. I'm waiting on some rule clarifications from a local racing series, and then I will make my move. If they allow twins I'll do that, if they only allow a single I'll focus on that.
I guess the lesson learned is watch out, there are a lot of gt47-88's out there and some are for 800hp and some are for 1200. looks like i was trying to make 900rwhp or more with the 800hp one.
I'll start a new thread when I decide what I'm doing.

Was talking to one of the PTE guys for a while, he felt that the turbo croaked from being over spun and that the backpressure might have been way too high. Given that I was only running a 348ci, I'd say those guys running GT47-88's with 348-408ci setups might want to call over there and see what they say regarding backpressure. Seemed to be saying that I would have been okay with smaller cubes but heck that's like running a darn 5.3 truck motor.
