The August 04 Motor Trend has a really interesting "Tuners" short write-up of the base 450 hp LPE GTO, (12.6 and 113.5 1/4 mile) that also outlines suspension, wheel, tire, brake and other engine mods. available. Worth reading. It mentions a 130 hp supercharger package, not tested. Anyone have any dyno #s or updates on the Magnuson or other s/c mods like the Arrowhead Performance car? I can see the coming s/c vs. normally aspirated wars, which make us all winners.
