Not to thread jack, but the car was capable of low 13's, just never got the chance to run in it in cool weather. Altitude density is ridiculous here in the summer time. I managed to pull that 13.6 in my sig with a burned up stock clutch in very hot and humid weather. It was an '05 model AP2. Stock I ran 14.2. My mods were, AEM-V2, Ricks header, berk TP, invidia exhaust, vafc tune, 4.57 gears with comptech reinforced diff, and later added ACT clutch with comptech flywheel. Made 216 whp and 151 ft/bs on a dynojet. I spent a good bit of money to get it running respectively fast so $1,500 for a pulley and intake is a bargain for the performance gain on the SRT-6. Can't wait to purchase those items. Anyway long story short the car was wrecked/repaired and never the same after so I traded it in on my truck. I was looking to buy another, that is when I discovered the SRT and we lived happily ever after.
