I have a 08 shelby gt 4.6... trying to decide what the best direction to go in for the most hp. For my money.. would like the hear anyone that has personal experience with what mods work best and which parts work well together.. thanks guys..

It's a Shelby so I suggest you try to keep it as original as possible. If you must have the extra HP, a supercharger would be the best bang for the buck and you could always reverse it back to stock if you decide to sell the car.

supercharger has most bang for buck. Sometimes this is too big of a first step for people. CAI and tune is always a good go to starter. Need the tuner anyways for future bigger mods. LT headers and cams work very well together. These will be worth decent horsepower. You could do heads if you want. these are considered boltons and will be worth good power. much more than cams, LT and heads and you are at nitrous and boost. Also better gears in the rear end will not make more power but will get the car out of the hole faster (and they are fun)

+1 on supercharging. That, however, will run you typically $6k or more but will result in 425 RWHP or more, no ey dependent. If you can't go that route, CAI & a good tune p.us long tube headers will put you somewhere around 305-310 RWHP. After that, there are a few mods left that'll gain you a few more hp here and there.
