Okay, I have a few questions that I hope will get some good solid answers.
Are centrifugal blowers that much more likely to blow out an engine compared to roots style?
What precautions would I need to take to put 8 lbs of boost into my car to run a completely safe tune, to have a strong daily driver?
How much $$$ am I looking at total, with all the precautions involved?
How many people have had great experiences with superchargers, and haven't had severe problems?
Thanks

Centrifigal blowers tend to be slightly more "dangerous" to your engine because they just plain produce more horsepower, and when not accompanied by a good tune or competent fuel system you will run into problems. In order to make it safe you'll need more fuel (injectors, fuel pumps, fmu possibly if it comes with your kit) and a good tune. With 8 pounds of boost you shouldn't run into many problems, especially with such a low mileage motor. An aftercooler would be a nice, but expensive compliment to the supercharger.
Basically, just get it tuned, and don't always drive it like you stole it and you'll be fine.

I don't think it's the "power" that kills the engine, but rather the rpm. Roots/twin screw blowers as well as turbos don't need to be rev'd to make max hp. Whereas centrifugal s/c's usually make max hp at or near redline.
As for precautions - Fuel, Fuel, Fuel. Make sure you have more than enough injector (big), and more than enough pump. You never want to skimp on fuel in a forced induction car.
