MOOVS-what was your 60 foot?
Maybe another thing about building some boost would be that you can keep the weight on the rear tires more. I did some experiments on the street with my car. First thing I found out by checking was that the old BFG dragradials do get nice and sticky after a short dry burnout. Second, with the pressure at 15 psi, I see the entire width of the tire on the road from the burnout. Third, it is not dropping the clutch that spins the tires, it is when the turbos hit. So I move and then spin. Maybe a harder launch would actually be better in this case. Also maybe less air pressure.
