my 92 s-10 5 speed manual ~90-95 (speedometer only read upto 85 which was marked, and 90 wasn't marked). that was fun. that was almost once to twice a week for me almost 2 years ago.
then my dads 90 something ford contour i could only get it upto ~110-115 (speedo read upto 120mph) but ran out of road to keep pushing it. i effing loved that car. i locked up the motor after a failed e-brake slide attempt.
my current 98 ford escort i've gotten upto ~110mph (kilpatrick turnpike just out of tulsa south to oklahoma city) and then i backed off, looked up just in time to see a cop ~ 1/4 mile back switch lanes, flip his lights, then turn them off and pace me til he pulled off to help some stranded motorists. i was hella lucky. (this was last year as well).
oh and btw, all cars were stock.
i was riding in my uncle's 1 ton dually and he had gotten it upto ~120 or so (pegged the speedo) on some backroad in midwest city one night. that was one of the scariest moments of my life. oh and he's a mechanic so he had a new computer chip, and new air filter put in.
