Went to the track this weekend. Full street weight. 19s with Mickey Thompson’s. Made 5 passes. Fastest was a 10.02 at 139mph when the trans let go between the 1000’ and 1320’. It wasn’t the shift that caused the break I was already in 4th and half way through the pull. Tim king is sending me the core and will diagnose it later. Wish I could load a video.
