Blown Cobra (from street racers corner)

[Rice Hunter]

I am in the final stages of getting my 99 Cobra supercharged. In that, I mean, I have finally pulled the money together. I decided to go with a Vortch supercharger that claims to be able to boost up to 490HP with the aftercooler. Sure this is $6000 without cost of install, but hey, when you want to do something, do it right. Right? (Maybe I should start off with 430-450HP?)
I'm putting on a Borla cat-back also. Anything I absolutely need to not blow myself up? I seem to talk about this stuff a lot, but know only a fraction of what I should. I'm still learning. Any hints?? I have not mods yet on the car, and have gotten the impression that supercharging isn't the best first step. But it is now or never for the supercharger due to time constraints.

Oh yeah, I want to put the Cobra R windsplitter front facia on after I supercharge. Does anyone know the cost of installation and painting of stuff like that, on average??

P.S. I put this post up and got some good feed back in the street racers corner, but was also referred here. They said you guys are the ones to talk to!
