Can anyone recommend a good book?

Looking for a book on early 911 race cars, with an emphasis on the technical aspects of what the engineers did. I have books on the results and all that, but want to know more on what they did to the cars themselves. Anybody know of anything along this?

Not specific to Porsche, but he talks a lot about the 911 IROC cars, as well as some other cool Porsche cars.
