"The "downhill" discipline involves the highest speeds and therefore the greatest risks of all the alpine events. Racers on a typical international-level course will exceed speeds of 130 kilometers per hour (80 mph) and some courses, such as the famous Hahnenkamm course in Kitzbühel, Austria, speeds of up to 150 kilometers per hour (93 mph) in certain sections are expected. Competing in the downhill event requires of racers considerable strength and technical expertise."
Couldn't find exact data on the Super G which does hit higher speeds, but I did watch it once on American TV and it was definitely 110mph. Although then again, I'm just a mechanical engineer so its not like I understand the metric system, or measurements in general for that matter. So I'm sure that you are smarter than me and know what you're talking about more than I do.
