Anyone have any Pinewood Derby tips/tricks?

Put a Hemi in it!

I was wondering when someone would say that - lol

Thanks for all of the great tips. I certainly dont want to break any rules, I just want him to win at least one race.

Our pack has quite a nice setup. They use double elimination so everyone gets a couple of chances to run. The track has a flat starting gate, and a sensor and timer at the end determine the winner and times. Amazing how some of the cars lose by just a hundredth of a second.

Keep the suggestions coming. The race isnt until March 20th. I'll post a pic of the car when it is all done.
