You guys are all right on..You need to lower and completly seal the underneath of the vehicle to prevent air from allowing the lift factor to take place.. along with all the required suspension...But...if you do not have the HP and the right gears, it will take you forever to achieve your top speed. John Boscema hit 188 mph with I believe 440 rwhp..He needed the additional HP to achieve the 200 mph mark. He has since accomplished this. But you need the lower gears to hit your mark.
