Supercharger prep?

[impymech]

I got to drive a 03 cobra today and I have to say that it was the baddest meanest car I have ever drove! I have a 03 GT and I am now set on getting it supercherged. I have seen some of the web sets for different companies selling blowers and they all seem to claim that you can just bolt one on and away you go. I find this hard to believe. When Ford built the 03 GT's did the engineers have us mooders in mind? Will the stock engine components, suspension, transmission ect... be able to handle another 100 HP? I know for a fact that the plastic intake manifold was not engineered to handle that and im pretty sure thats going to have to go. I guess my question is what else would need to be preped or replaced? I don't plan to race at the track all the time and this car will be my daily driver. I want to be able to get the power in a safe manner and still be able to take a 600 mile road trip. Thanks for any input.
