1) Bog - during a hard launch, this is the drop in engine speed and power resulting from using too little throttle while slipping the clutch, or engaging the clutch too quickly. Or both.
2) Powershift - upshifting at wide-open-throttle; a good way to expire a transmission in short order.
3) Double-clutch - a downshifting technique used in cars with non-synchromesh gearboxes. The idea is to match the transmission's layshaft speed to the gear cluster speed. The driver depresses the clutch, moves the gear selector to neutral, and declutches. While in neutral, the driver rev-matches the engine and layshaft to the speed of the gear cluster, then depresses the clutch again, selects the lower gear and declutches. This keeps the bits going the same speed at the same time, avoiding a nasty gear crunch. All modern road-going transmissions have synchros, which magically speed up the layshaft to the speed of the gear cluster so you don't have to.
4) Dogbox - transmission with dog rings instead of synchros. Dogs do what synchros (or double-clutching old farts) do, but faster and with a big clunk.
5) Cat-back - the portion of the exhaust downstream of and not including the catalytic converter.
6) Skidpad - circular piece of pavement used to determine the maximum lateral acceleration, or ultimate grip, a vehicle can generate. See #61 "1.0g"
7) Apex - the point on the inside of a turn that bisects the angle of the entering straight and the exit straight; the geometric center of the turn.
8) Backpressure - the pressure in the exhaust system, typically measured near the exhaust ports.
9) Redlight - crossing the stage beam before the green light is lit; this will get a sub 0.500-second reaction time and an automatic loss (see 0.500).
10) Honda -Soichiro Honda's Honda Motor Company sold its first motorcycle in 1949. Ten years later, the first Honda, the C100 Super Cub motorcycle, was sold in the United States. Eventually Honda sold 30 million of them, making it the world's best-selling vehicle to date. Ten years later, the first Honda automobile, the 9600, was sold in the United States. Today, Honda is reknowned for its powertrain excellence and endless possibilities for engine swaps.
