[QUOTE="black4vcobra, post: 13216602, member: 82394"] Those of you interested in adding a Vortech supercharger to your 1999 Cobra might find my experience useful, well, the few of you remaining anyway as I'm a few years behind the curve on this. I bought a Vortech V2 E-trim, bracket, discharge assembly, SCT BA2800 MAF and Anderson power pipe from a guy with a 99 Cobra for $1300. Bought 03 Cobra fuel injectors from another guy for $100. Bought a DivisionX 340 lph fuel pump from Lethal Performance. Purchased a 3.48” drive pulley and oil feed/drain lines from Superchargersonline.com. That left me with figuring out the hardware situation. As it turns out, no hardware kit for 1999 Cobras and the 01 kit is different. Knowing 96-98 Cobras are similar I took a look at this: 96-98 Cobra hardware kit - $78 [url=http://www.superchargersonline.com/index.php?main_page=product_info&cPath=510_1218_1340&products_id=7557]Vortech 96-98 Mustang Cobra 4.6L Mounting Bracket HARDWARE KIT [V4FK100-004] - $77.95 : SuperchargersOnline, Worlds largest Supercharger Resource.
