If I was going to do a forced induction setup, it would definitely be a supercharger. Turbos require too much plumbing and take up too much space. Not arguing b/c turbos are the best for making power, it's just personal preference. Not to mention turbo cars are usually a little too quiet and docile sounding for me.

The main thing that keeps me from going that route, other than the cost, is packaging. I don't really want to hack the frontend of my car off, fit all that stuff, and then try to lay the car's skin back over it. Nitrous is much easier to fit on the car, lol. Then again, I'm not trying to outrun everyone and set records either.
