I bought a roughly new 2008 v6 Mustang a few weeks ago.. I already know the v8's are much more powerful and faster. But to be honest, I'm more of a city driver and buying the GT would make a huge impact on my insurance. I'm already very satisfied with the performance on the v6's.. But I'm not the one to push down the pedal completely from a dead stop all the time.. By the way, is it bad for your engine if you rev it that hard from a dead stop? I don't completely push it down all the way, but it makes a pretty loud, but satisfying noise when I take off. But I was wondering if someone could give me some tips on performance parts I could buy.. I heard supercharger kits add some serious HP to any car.. Any ideas? For the record, I am more of a casual driver than a person thats all for performance.. I plan to make some simple mods to the car performance wise, then I am going to make some changes to the appearance of the car later on down the road.
