Racing Series
A few top classes like Formula One limit only the displacement and air intake mouth dimension. However, in 2006 air restrictors (as well as rev limiters) were used by Scuderia Toro Rosso to facilitate the transition to a new engine formula.
Many other racing series use additional air restrictors.
- Formula 3, 2000cc, 215 hp
- Deutsche Tourenwagen Masters, 4000cc, 470 hp
- FIA GT Championship (now FIA GT1 World Championship) and other series using FIA GT regulations
- Le Mans Prototypes used in American Le Mans Series and Le Mans Series have restrictors based on precalculated tables depending on the type and size of the engine and fuel
- The ALMS in the 2010 season combines both LMP1 and LMP2 into a single LMP class on all races except 12 Hours of Sebring and Petit Le Mans; LMP1-categorized cars use a 5% smaller air restrictor compared to LMP2- categorized cars to balance performance in the races

Famous quotes containing the words racing and/or series:
“Upscale people are fixated with food simply because they are now able to eat so much of it without getting fat, and the reason they don’t get fat is that they maintain a profligate level of calorie expenditure. The very same people whose evenings begin with melted goat’s cheese ... get up at dawn to run, break for a mid-morning aerobics class, and watch the evening news while racing on a stationary bicycle.”
—Barbara Ehrenreich (b. 1941)
“In the order of literature, as in others, there is no act that is not the coronation of an infinite series of causes and the source of an infinite series of effects.”
—Jorge Luis Borges (1899–1986)
