You know toohighpsi commented on your unfortunate event and said "Unfortunately the newfound power was a bit too much for the drive-train and failed the rear and trans before completing a pass. The rear locked up - split the transmission completely in half - and caught fire at the starting line setting off side airbags before it could be contained. "
with that being said it's hard to believe that a trans rebuild had anything to do with the failure.
reminds me alot of the carnage that happened to parish8 back in april of 18.
