Hi folks. As above are available free from the FIA Website: https://historicdb.fia.com I have down-loaded quite few few and some interesting things come to light! e.g.: Audi 90 Q 20V The form is quite large. 61 pages. Thus, Audi went to a lot of trouble to homologate loads of parts including: Ur Quattro S1 brakes, suspension, wishbones and steering. They did not homologate: The fabricated tubular exhaust manifold (Cast iron only. Although they built loads of cars with the tubular.), the Hitachi sequential injection, the Carbon Fibre prop shaft or the 6 speed box. These could have been used in Group 'N'. The AUDI competition dept. went to lots of trouble for a car they were never actually 'permitted' to used in competition! Why did they not use the best N/A engine they ever built? Because the new Audi management were accountants and marketing people, not engineers, who only knew ' the price of everything and the value of nothing'! They wanted a 'sexy' , although 'nasty' and very heavy, 3.0l V6 'anchor', to attract the rep-mobile buyer! Sad, or what? Most interesting is that there is even a separate form for the V8 head on the 16V block. Lots of good photos, but no dimensions for machining the two to fit!
Hi Dave, I found that one as well a while back, did you also notice many of the pictures in the Golf forms are much higher quality than the ones we had previously?
