163 mph on the speedo and by the math: 6,200 rpm, 5th gear, TKO 600 w/.82 ratio, Goodyear F1 315/35R17 (25.2" diameter per manufacturer), 3.46 rear ratio. Very loud, very windy, very P.O.'d wife.
Took about ten maybe fifteen seconds to accelerate to that speed from around 60. Was out playing with a buddy in his SL600. He was feeling froggy so I had to show him what an old Ford could do. Unfortunately for him (and probably fortunately for me), he petered out at 155 thanks to electronic governor. I was only pulling him slightly until his computer choked him back. Yes, it was on a public highway. No, there was not another car in sight.
