First of all, pilot tracks. Have someone sit in a sled and push them down the hill. Standing is recommended because it pushes down the snow and hard-packs it. Second of all, curves. Small curves in your line increase your fun, because it keeps you moving and tilting, always leaning in one direction or another. Third, sitting down goes faster then on your stomach. Finally, ramps. Get some kindof ramp setup about half way down and the entire experience builds up to a jump half way, and then the slowdown at the bottom.
Enjoy your snowcoaster.
