Quick times can generally be boiled down to 1 simple thing HP to weight ratio.

4800 pounds is a LOT of car. The old rule of thumb is 1/10 second for every 100 pounds in weight reduction. If it was me and if I was SERIOUS about getting into the 13s the first step would be to get rid of all the garbage I could. Not trying to be mean here, but your sound system will likely cost you between 2/10s and a 1/2 second.

Build the biggest engine you can, throw NOx on it and drive it till it blows.
