I wonder if any calculation would be accurate in a turbo, supercharged or nitrous application.
I remember I was racing a 240z turbo (punched out motor) at mission. I was ahead of him till the 3/4 mark of the track. I spanked him in the 1/8 mile. BUT next thing you know it he caught up to me and did a 11.80 or something at 115 or 116mph while I did a 12.1 ish ET.
