So how fast is the mad truck( 2004 f250 ext. cab 4x4 35" tires and 5.5 lift kit 6.0 powerstroke) well I got into a race with a 2009-2011 Corvette. I was driving home and stopped at a light, corvette behind me. Light turned green and I took off normally, and got ahead of the car in right lane. As soon as I had about 3-4 car lengths on the car on right, the corvette decided to get to right lane and hammered it down. I figured he was going to so I nailed the truck when he got next to me. I pull on him as soon as I hit it and started to pull move and car lengths about 5-6 when I was starting to come up on a curve so I had to let up and hit the brakes to slow down. That's when the corvette went around me about mid curve passed me. We made it to another light, and we both made a left turn when the light turned green and it was on again. I rolled into throttle to not break tires loose and the corvette nailed it down and got 1 car length in front of me, then I hammered down, and blasted pass the corvette and pulled about 9-11 car lengths before slowing down, no curves to save the vett this time. He never came back up to me, must have broken the poor guys heart.
