Hmmm...not sure if you have your priorities exactly straight for this project, no offense. I'm surprised no one has recommended Corky Bell's "Maximum Boost". It's a really good book to introduce you to the basics of forced induction. Not too technical, but it'll give you a good grasp on things.
And, yeah, why not skip the turbo timer and spend the extra minute or so listening to the radio or picking your nose (my personal favorite).
Oh, and it's always a possiblity that your engine will go boom. It just goes with the territory.
