the fun of drag racing isnt in what time you, but the road to getting quicker.
eg my 1st run in the 33 was 19 secs because I blazed the tyres off it in 3rd.
Just get out there for a night, first few runs are generally crap and you will get better.
then once the car (not the driver) cant go any quicker start changing a few things to try and get quicker and more consistnt
