There are lot's of little tricks to ik out a little more out of any car, should be fun to see how much time can be shaved by using them.
#1 would be to put the car on a diet. Run the fuel tank really low, remove any thing you can to save weight, things like emergency tire repair kit, cargo cover, floor mats, etc.
#2 others could be pumping up the tire pressures to 50 PSI to reduce rolling resitance, using unleaded race fuel might bump up the timing a little and make more power, performance muffler, clean up the exhaust mannifold or build a header, intake, etc.
#3 other things like NOS, turbos, or motorcycle engines for those who really get sick.
The first two should help a little but the smart will still be very slow.
