Somehow avoided a blowout on the rear tire, would have been pretty bad if it happened at the finish line.
Got some good 240 fps film of the burnout and launch, however.
Basically you can see the tire make contact with the front of the fenderwell at the hit, which bent the metal outward towards the tire. Then, as I went faster down the track, the tire grows in height, and that bent piece of metal was slicing deeper and deeper into the tire. There was some slight smoke in the interior at the finish but at the time I didn't really even notice it. Still ran an 8.90 at 152 with the back tire being eaten alive by the bent fenderwell.
When I saw the time slip at first I though I might have lost a plug, as I was off 3/10ths and mph was down by 6. So at first I thought I might have hurt the motor. But as soon as I got out, I saw the tire, I was pissed but happy at the same time. Pissed because my weekend was over. Happy because the motor was just fine, and the tire somehow held together so I didn't go into the wall.
I am going to check everything under the car, do some additional trimming, and try again next weekend with a new tire. Not really sure why it did it this time, I have ran this size tire before with no problems. I am going to adjust both LCAs to move the rear tires back a 1/4 inch or so.
