He significantly lightened his car. This means better acceleration at lower speeds, when it's all about getting the mass moving. Someone who has a regular 3200-3300 lb SVT and power mods to get those times would be able to use the power to both accelerate off the line AND overcome the drag at higher speeds. Lighter cars and boxy cars tend to have lower trap speeds, heavy, powerful, aerodynamic cars have higer trap speeds. But, it all comes down to the time... and lighter always wins there!
