How much does my weight effect my sprinting times? 40 yd dash for example.?

im pretty slow. 5 foot 7, 169 lbs. junior in high school. im not fat, but i do have a good amount of excess weight.

at the moment my 40 yd is around 5 seconds. very turtle like. if i lost say 15 pounds in the next half year, which isnt hard for me, (just watch the eating), how would my 40 yd dash time change?

thanks all
