As most ya'll m0f0's know, my Vehicle Speed Sensor is broke still (sell me one please) and my speedometer is at 0 (mileage dont go up either but cruise control dont work

) Anyway, I was driving down a long open road late at night in Alaska, and decided to push the car to see if she still had it in her... I got her to 500 rpms before redline in 5th and decided that was good enough...
Can anyone tell me how fast I was going?
