You can always go faster by taking weight out of the car. Empty the washer fluid, take out the passenger seat, run with only enough gas to have fun a get to a station afterwards. Buy a bag of ice and ice down the intake manifold before you line up to run. Take the belt off and push the car to the line. Lots of no cost tricks. Leave the carpets and jack at home. Practice helps. I get the most satisfaction improving my performance as much or more than the cars.
