I was reading the DQ at Indy thread. There is a little misinformation. Rodgers was running too large a pulley which in fact gives those motors more HP at high RPM according to Jimmy Ronzello who works for Ford on the Cobra Jets. The CJs turn such high RPM that the belt doesn't slip on the larger pulley at high RPM and ends up producing more boost than the smaller pulley. That is why they have a 120 lb weight penalty.
