When I test drove a six speed CF, my first 0-60 run caused a noticeable smell, a smell that was most definately clutch. The smell stuck around for a good 15 minutes, the whole while I had to wait for the smell to go away so I could take it back to the dealer! I started from a roll in 1st and banged second pretty good, but nothing that should have warranted getting the clutch hot enough to start to smell. It was enough to scare me into an Autostick, an option I never planned on getting.
