Yeah... Just definatley blew up the z6 :P

So she was misfiring earlier today... I took a trip home from school yesterday to take the wheels off, put the stockies back for winter and raise it back up. She was misfiring at full boost with open DP (exhaust got ripped off by a speed bump, so I needed to come home and fix that too)...

So I pulled the plugs and gapped them down to .35 -- they were really inconsistently gapped... So that was the cause right there, spark blowing out. Took her on the higway and man with the new gap she was running so strong. I got to the end of the road and whipped a u-turn -- the higway ends there, it's so nice. Pulled on, 1st, 2nd, 3rd, 4th... 120mph and a subtle "BOOF" is the best way I can describe it... and the power just stopped. Downshifted to fourth, entire road behind me is smoked beyond being able to see. She is making a really weird noise, kind of like a motorcycle... and making zero power. I'm at 4500rpms in third now just to keep speed, and boosting 5lbs. Its hurting. Off the higway, thank god i'm close to home, up the hill... 10psi in 2nd gear just to MAKE it up the hill.

Just compression tested her... 0/180/175/180. No milky oil or coolant... just pulled the valve cover...

I wonder what it is? Guess I'm going to pull the head in the AM... but I've never heard of zero compression before. What do you all think?
