Does this sound blown to you?
I finally got my 3" turboback in today, and haven't driven the car in a week since I did all the work to it....... well, about 3 hours after getting the exhaust on and doing a couple test runs, I did something stupid. At 12 pounds the AFR's were in the low 11's so I was beating the **** out of the car, and mis-shifted to 2nd. Well, as soon as I got it back in gear, it was running on 1 rotor and wouldn't accelerate at all. Luckily I was on some backroads so I got it home, barely, where it just shut off. I checked all over for vacuum leaks, got nothing, no blown off intercooler hoses or anything, and when turning it over, there is an obvious miss in compression. I gave up on trying to start it tonight, cause it's dark out, and it flooded out, but I will check the compression tomorrow. I'm pretty sure the test will confirm what I fear....... but does that sound pretty typical for a blown something or another?

I got off my *** and went out and de-flooded it, and it started and sounds just like our lawnmower........ oh well, it was a good 20 miles of driving it......

With the AFR good I can see why you wouldn't expect it to detonate.
Hitting the rev limiter is rarely a problem.
Before pulling it, I'd pump some MMO in the leading plug hole of the low compression chamber & let it soak a day, in case it's just a stuck seal.

Took out a plug, only 1 face with compression on back rotor. It is soaking in ATF now........ I checked the turbo and it is still spinning freely, really no indication if anything went out through it I guess, though. I got my fingers crossed for a stuck seal, but I doubt I will get that lucky. It wouldn't be very likely for a seal to stick like that would it?

MaczPayne is right. A stuck seal is usually from storing or overbabying.
But - when you buzzed it some of the carbon flying loose may not have blown out cleanly.
It's a long shot, but it's worth a try.
Good luck,
