Three books come to mind...Turbochargers by the late Hugh Mcinnes.....Maximum Boost by Corky Bell and Turbomania by Bob Tomlinson....A little different aspespect, insight and direction on each tome; however each a good readin its own fashion The Tomlinson book tho written in giggly school girl creative comp style has alot of meat in it about setting up air cooled VW engines in both draw through and blow through types.You may tire of the constant hyping of the latest CB product that will take over the industry but there good to be garnered.But remember like much of the stuff they have touted over the years,much is NLA....
