This is going to sound like one of the most dickheaded thing I've said on here, but you just wrecked your car so you have plenty of time to read up and have a decent idea of what you're doing before you even start looking at superchargers.
I'm sorry to hear about your wreck, but at least it gives you time to learn. I sound like a dick in my other post too, but it makes me kinda mad when people ask questions like "will I need a tune?" I'm settled down now though

There are tons of threads about superchargers and KB installs, just search for them. Google is your friend :yes and you can learn a lot by reading on KB's website and web sites of other twin screw or roots style blowers
