It's probably a built auto or a TH400 racing transmission. There are some built auto trans that are running those kind of numbers. I believe the record for the 6spd supra is in the 9's w/ full weight interior. This was an old record made by Ryan Woon from WOTM. His new setup using a GMTH400 and more N2O estimated 1/4 time is in the 8's w/full interior trim.
