MPH wins on the street, even from a dig. Now that I only run at the track, I am more concerned with ET. When I street raced, my mustang always ran mph that was equivalent to a car running a few tenths to a half second faster. Put it this way, I got a move from a low 11 second (11.0-11.20 ET) motor car, my car only ran 11.90's on the motor. He came halfway up my door before the rpm's got to where I made decent power (vtec yO), then I actually pulled a car through second and third. At the track, he would have left me at the starting line.
