got a case last night at the track, half price so couldnt pass up the deal.

anyone have any input good or bad about this race version oil? (royal purple 21)

BTW, ran fair last night; 1/4- 12.085, r/t- .520, 60'- 1.880, mph 116.59
ran on bfg drag radials at 20psi, launching around 2500-3000 but, still wayyy too much wheel spin and its killing the 60' times. maybe try 18 or 16 psi at about 2000-2500 on friday.
