Most of the differences in building engines for off road SCORE or desert endurance racing purposes, say experts, concern the endurance factor. The annual Baja 1000 is actually 1,300 miles of punishing off-road racing. The winner will take 25 or 26 hours to complete the race, so the engines have to last for that long.
If you leave leftovers or any food out too long, it will speed spoilage. Two hours is generally the max they should be left out, though the sooner you refrigerate them the better (remember to factor in the time it takes to drive back from the grocery store, and the time it takes you to unpack your groceries).
