I like the term "speedholes" reminds me of a Simpsons episode where Homer is a Krusty the Klown imatator (spelling?) and is buying a car. The Mob starts shooting at him and they hit the car. Homer asks what the holes are in the car, and the salesman stats, "they're speed holes, they make the car go faster."
Next scene Homer has a pick-axe and is putting speed holes in his car.
