I have only foot braked the car once in the last couple of years and it ran 10.20 leaving at about 1,800 rpm in the middle of the summer. On my car I think the brake is worth about a .10-.15. Hope this helps.

Yes this is exactly what I was looking for. Now if you can go a low 1.30
should I be able to do the same because my mph matches yours? I have 4.56 gears with a 29" slick with a 1.80 first gear and 5500 stall.
