2010 Shelby 685RWHP/ 701ftlbs tq.
Car has 2.3 tvs , 2.4 upper pulley , 90mm idler, id1000 injectors, Kb BAP,lethal o/r X , flow master axle backs,123mm Jlt CAI , tuned on E85 . Have AR long tubes waiting to install, and twin 67mm VMP TB.
I expected a little more. Was it a mustang dyno? Guy below you has similar mods without e85 and has more power.
