Books?

[calereeves]

What books out there are better than Turbomania? I know there has to be at least one out there that isnt a catalog for the company that puts it out (C.B.). Dont get me wrong, it appears that C.B. performance has good stuff and good prices, but their book is lacking. Are any of these others solely for VWs or is it general turbo theory? That would be okay, but I really want something stictly VW. Any ideas?
Thanks,
Cale

Oh yeah, something with a little info on twin turbos would be nice!
