Some Carnage Shots

[kahl23]

Well as I posted in this thread http://www.dsmtuners.com/forums/drag-strip/311252-finally-made-into-11s.html there was a little accident a few weeks ago going from the top of third to second, whoops. After we replaced the rockers and lifters that we'd destroyed the car ran great, but we still really should've done a compression test. The next street night something was wrong, it was only running 12.0Xs at 115 mph, versus an 11.9 at 122 on the first pass before the accident. A compression test showed that cylinders 2 and 3 were down on compression, so we pulled the head. While we were at we decided to check the flywheel bolts to see if they were loose. They were all finger tight WTF. Underneath the flywheel it looked like the crank and flywheel had been melted together, pics below. My question is what exactly caused this, and is the crank still good? I'm going out on a limb here and assuming the flywheel is toasted.

Was red loctite used?? The mating surfaces will fuse together because of the high heat from slipping the clutch especially if your doing a couple of back to back runs. You can probably still use that crank, just use a long flat file and be careful not to remove too much material.

Next time use the high strength loctite and rub some high temp nickel antiseize between the mating surfaces of the crank and the flwheel

The bolts backing out caused it. The pressure of the clutch with loose bolts at high rpm is what melted it together like that. I would just clean up the crank use some red lock tight with a different flywheel and call it a day. I would also install a dowel pin.

Sorry, I should've said that red locktite was used copiously. So copiously I was worried it wouldn't come off again
