* Blanket – a ballistic cover, typically over the supercharged intake manifold assembly to contain shrapnel, in the case of an explosion.
* Blow – see Blown.
* Blower – [[supercharger]] (occasionally [[turbocharger]]); in '90s, generally grouped as "power adder" with turbocharger and [[nitrous oxide|nitrous]]
* Blown – supercharged, when describing a functioning engine; wrecked, when describing an engine failure.
* Blowover – flipping of a car, due to air under car lifting front wheels
* Breakout – in [[bracket racing]], running quicker than dial-in; also "breaking out".
* Bulb(ed){{citation needed|date=October 2012}} – synonym for "redlight"
* Bump – (also called on the bump or in the bubble) a driver is ranked by qualifying order if they are ranked 15 or 16 in most skill classes they are placed "on the bump" if the next driver improves and gets a better score that driver is eliminated and has to do another run to requalify. If they mess up on all qualification days, do not make it to elimination, or lose the first or second round that driver is eliminated and "placed on the trailer" and sent home.<ref>{{Cite web|title=NHRA Glossary|url=https://www.nhra.com/nhra-101/nhra-glossary|access-date=16 May 2021|website=NHRA|language=en}}</ref>

* Heads-up racing – a non-handicapped racing style where both drivers are started at the same time. Used in all professional ("pro") classes.

** Holeshot win – a race won by a driver with a slower elapsed time but a faster reaction time.
* Hook[ed] up – good traction between tires and track resulting in increased acceleration and reduced slipping or smoking of tires.
* James Bond – when a driver's reaction time is seven thousandths of a second after the green light (.007).  A "James Bond Red" is a reaction time of -.007 seconds (red light), which is disqualification unless the opponent commits a more serious violation.<ref>{{cite web|url=http://www.dragracecentral.com/drcstoryprint.asp?ID=282395%7c2014|title=Drag Race Central – Presented by Summitracing.com 1-800-230-3030|access-date=17 April 2016}}</ref>

* Pedalling – working the throttle to maintain traction, or as a way to sandbag; "pedalled" it, had to "pedal" it

* Slapper bar – traction bar
* Slicks – rear tires with no tread pattern and softer rubber compound, for increased traction
* Slingshot – early front-engined dragster, named for the driving position behind the rear wheels (erroneously attributed to launch speed).
* Small Tire – Class of car where rear tires are shorter than or equal to 28.5 in and or equal 12.5 in of tread. This type of racing usually assumes that the rear frame rails and suspension are not radically modified.
* Standard tree – style of starting a race where the timing lights flash in sequence five tenths of a second between each yellow light before turning green. Original starting method before introduction of pro tree.
* Struck the tires – (also called hazing the tires, smoking the tires, or smoking out) loss of traction, causing them to smoke<ref>{{Cite web|date=28 August 2020|title=Guide to Troubleshooting Drag Race Traction Issues|url=https://www.onallcylinders.com/2020/08/28/guide-to-troubleshooting-drag-race-traction-issues/|access-date=14 May 2021|website=OnAllCylinders|language=en-US}}</ref>

* [[Wheelie bars]] – rear struts fixed to rear axle, which protrude out to rear of car to help prevent car's front from raising too high or flipping over on launch.
