mid 12s.. you lost some weight and gained some power changing the exhaust up..

i dont know what your 60 foot was on the 13.1111 run, so i dont know if that will improve much.. i dont know why peopl give track times without a sixty..

your gears are going to help you with a tenth probably, you came from 323s, so not a huge performance increase there...

do all the free mods, take out all the weight you can/want to... remove you filter when you go.. drop PSI to about 18 on radials..

your sixty will probably drop to a low 1.9 high 1.8... just dont under pressure the tires... drop just enough to where you dead hook NO LESS..

i would say a 12.6 would be very doable... but you will probably see about a 12.7-12.8..
