Actually, I was waiting to tell you guys this for a while now, but my dad used to own this crazy german car, something called a 911?
1965, I believe, 6 carbs and rwd, the good 'ol days! Anyways, he let my mom drive it one day, and she shifts from third to second at about 100mph. My dad says he literally watched the tach burry itself into 9k (or 10k, I don't remember what the tach went to) and the whole drivetrain SCREEEEEEAM for what obviously felt like an eternity, but he said probably 2-3 seconds, and the engine would have for sure hit around 11k rpms. My mom slams the clutch back in as fast as she can (she's a pretty handy driver, she's doing a 100mph pull in a 911, ok?) and without thinking, shifts into fifth and starts to slow down. My parents are staring at each other, my mom scared to death my dad will kill her, my dad scared his 911 is toast.
Well, like I said, my mom had shifted into fifth and started to slow down and kept going. The motor & tranny were both fine, and my dad drove that car for five more years before he sold it (the year after I was born). True story, and that's why one day a porsche will be in my garage instead of a dsm. =)
