1/4 Drag Advice Please

I want to take my'08 2.3 hatch to the track just to see what it will do. It is a bone stock car with 60K miles and I'm wondering what reversible things I can do to give me just a bit more performance. This is my daily driver and I have no intention doing any real mods. Just wondering about tire pressures, removing the air cleaner, running with very little gas in the tank, removing the spare tire, etc. Also it is an auto. Will I be better of leaving it in Drive or shifting?

Thanks!

Leave it in drive, lower tire pressure to about 20-25psi. If you have regular street tires.. DO NOT GO THROUGH THE BURNOUT BOX go around it, when you see the last yellow... GO. You may want to bring the rev's up to about 2500 with your foot on the brake before you let her rip.

In all sincerity, nothing will make a measurable difference on a bone stock car. Leave the air cleaner, and don`t worry about fuel. A gallon of gasoline weighs just over 6lbs, and even at near empty the 60lbs isn`t going to put a dent in the timeslip.

Go out there and get your first run in, and have a ball. Look at your first slip and see what the numbers are, like your reaction time and 60 foot time. Focus on whittling down your reaction time, and practice different launch techniques to impact your 60 foot time. On street tires, do avoid the burnout. Do three runs with whatever pressure is in them when you get there. Then adjust down to 25psi and see if it affects your 60 foot times. You didn`t mention if it was auto or manual. If it`s a stick, try launching at about 3000rpm. If it stalls out, rev higher next time. If it roasts the tires (it won`t), feather the clutch in a little smoother.

A bone stock car will not overcome it`s own ability to control performance. You can get the most out of it by following the fundamental basics of driving technique, but there`s really nothing you`ll do mechanically that has a significant effect on what it puts on paper. Go have fun, tell us how you do
