question: Explain to my mom why she can’t put gas in her car while it’s running “because race car drivers do it”.
comment: Well, there's no technical reason she can't. There's a small chance a running engine could cause a spark that ignites gasoline fumes, but the biggest reason for that rule is because distracted people do dumb things getting in and out of running cars, and cause accidents. It's just generally a good idea to turn the car off, because it eliminates the risk of problems like locking your keys in it, forgetting to put it in park, your kid/pet knocking it out of park, etc.
passages: Cars that compete in the NASCAR Xfinity Series (previously known as Nationwide Series) cars are powered by carburetors; in addition to trucks that compete in NASCAR's Camping World Truck Series.

   Vapor lock is also less common in other motorsports, such as Formula One and IndyCar racing, due to the use of fuel injection and alcohol fuels (ethanol or methanol), which have a lower vapor pressure than gasoline.

   Fuel injection in NASCAR
  
  Fuel injection in NASCAR reflects the technology used by production Toyota, Chevrolet, and Ford vehicles on the road today. Currently, no production automobile manufacturers use carburetors as a part of the fuel delivery system.
   After the classroom session, students practice fire fighting (especially important since many novice workers have never so much as touched a fire extinguisher) and extrication, the proper term for removing a driver, presumed to be injured and possibly unconscious, from his or her wrecked car. Drivers often lend their cars for these important practice sessions, letting novices inspect the car's safety and performance components.
   Gas classes were eliminated by NHRA in 1972.
  
  Section::::Engine.
  
  Because they were primarily built for racing, these cars typically had the engine swapped to a larger or more powerful one, or the existing stock engine modified (often heavily). It was very common to fit a Roots supercharger modified from original use on General Motors two-cycle diesel truck engines and mechanical fuel injection, manufactured by Algon, Hilborn, or Crower.

   BULLET::::- Episode 6: Team Solstice experienced engine sputtering, but were able to fix the problem by turning off the engine and restarting it. Team Avalanche lost a significant amount of air from their right front tire during the challenge but were able to re-inflate it.
  
  BULLET::::- Episode 7: Team VW had a problem with exhaust fumes flowing into the vehicle. After suffering for some time, they were able to correct the problem themselves.
   Laws exist in all states and territories that limit modifications done to vehicles and prohibit having nitrous oxide hooked up to, or even present inside a car. In most states and territories P-Plater (Provisional Drivers) are not allowed to drive any vehicle with more than six cylinders as well as turbo. In most states further laws impose strong penalties for street racing such as confiscating/impounding the vehicle and loss of license.
   Section::::Pit road.
  
  During a race, teams must pit several times for refueling and new tires. Teams are permitted five crew members over the wall at the start of the race; that consists of two tire changers, one tire carrier, a jackman, and a gas man. Once NASCAR gives the OK (usually once the leader begins lapping cars), a 6th crew member is permitted only to service the driver/windshield. With the 2018 NASCAR rule changes, the gas man is now not allowed to make any adjustments to the car when refueling it.
   He hit the brakes, hit the apex and then hit the afterburner. I was speechless. To see the best of the best doing what they do best is beyond my ability to put into words. If you haven't raced, you don't know what it is to be a part of this living, breathing adrenaline rush. If you have raced, you know exactly what I mean.

   Formula Mazda Racing features open-wheel race cars with Mazda Wankel engines, adaptable to both oval tracks and road courses, on several levels of competition. Since 1991, the professionally organized Star Mazda Series has been the most popular format for sponsors, spectators, and upward bound drivers. The engines are all built by one engine builder, certified to produce the prescribed power, and sealed to discourage tampering. They are in a relatively mild state of racing tune, so that they are extremely reliable and can go years between motor rebuilds.
   Section::::Equipment.
  
  Paid crash/rescue workers in NASCAR, Indycar, and other organizations, will have their equipment supplied whereas volunteers may need to spend their own money for the components that help them be prepared. For events that continue through rain or other bad weather, marshals must man their posts and perform their duties in all weather conditions. In the United States it is strongly recommended that anyone directly involved with activity on the racing surface follow NFPA 610 guidelines.

   BULLET::::- Episode 6: Team Hemi-Cuda had water in their gas tank, bringing the car to a full stop. They lost more time drilling a hole in the side of the gas tank to drain the watery gas, and still more time stopping to repair the hole. Team Lexus lost time when pulling a U-turn on a highway and getting stuck in a ditch. Team Lambo lost time when pulled over by police.
   Dave Moody of Sirius XM NASCAR Radio said of Denny Hamlin's take on the incident that while Hamlin "is entitled to his opinion...[am I] the only one who’s tired of hearing drivers say, 'NASCAR should protect us from ourselves?' Brian France and Mike Helton don’t drive race cars. Drivers do. These are grown men (and women) who can handle their own affairs, both on and off the race track. They do not need an 'authority figure' to teach them right from wrong."

   In 1974, Johnny Rutherford's wife Betty scored for him in his team's pit area. She was perhaps the first driver's wife to spend the entire race in the pits. Rutherford won the race, and Betty's presence drew some media attention, leading many other wives to follow suit in future years.

   Of his time with Guasco's team, Emery said, “Driving the Pure Hell was the most fun of anything I ever did. There was no money to be made doing it, but we did it because we liked racing.”
  
  From Guasco's AA/FA team, Emery went to the fuel slingshot of the Rousin-O’Hare team in 1970, where he spent six months and won TF/D at DIMS.
   The stock car racing organization will have a special authorization code that will keep hackers away from tampering with the vehicles using workaround programs. Since the cars run on Sunoco's Green E15 fuel mixture, the new fuel delivery system will move the Sprint Cup Series towards more alternative fuels. All the sounds of the NASCAR stock cars are nearly identical to their carburetor-powered ancestors; the new vehicles even function the same as the "Gen 4" and "Gen 5" vehicles. The ability to download information from the electronic units of the cars will play a role in the elimination of tandem drafting that has hampered NASCAR in recent years.
   In 2014, Münter began racing in ARCA with Venturini Motorsports. She ran Daytona in the No. 55 Go 100% Renewable Energy racecar, where she was wrecked by a spinning car on lap 28 and finished the race in 28th place. Her second race of 2014 was her first race at Talladega Superspeedway where she finished 14th in the No. 55 Blackfish (film) race car sponsored by activist and creator of The Simpsons TV show, Sam Simon. She then finished 12th on the lead lap at Chicagoland Speedway in the No. 66 PrairieGold Solar/The Solutions Project racecar.

   Carburetors were still in wide use in both passenger automobiles and with the NASCAR vehicles during the early 1970s; requiring plenty of physically-intensive labor from the people who would maintain the vehicles between races.
   After two full seasons of fuel injected engines, it is safe to say that the performance is on par if not better than their predecessor. Drivers can actually save more fuel under caution by shutting the car off as fuel injection takes far less fuel to restart. Teams can also make minute adjustments prior to the race in order to slightly detune the engine to a more fuel efficient setting. However, the change has further broadened the gap between top tier and underfunded teams as the latter cannot afford to hire a separate employee to monitor and adjust the settings while the former can.
   The feat is considered physically demanding and mentally draining. It is similar in concept to the established discipline of endurance racing, but without the help of a relief driver, and the driver withstanding the very different physical demands of an Indycar and a stock car. 
   In 1964, Hartman started competing in up to five stock cars races in a weekend, driving with his father and uncle. "When we had the time," Butch said, "we'd sleep for a couple of hours in ditches alongside the road. When we didn't, one of us would stand on the running board of our old Buick and fuel our pickup truck with a five-gallon can of gas while we were tearing down the road. I think we invented in-flight refueling."

   BULLET::::- Plugger is a 4x4 off-road vehicle or "mud-plugger". Plugger is the most laid-back character at Silver Hatch and he never gets rushed or panic-stricken. In the UK version, he speaks with a soft Caribbean accent; in the US version, he speaks in a mild Southern drawl. He often uses his telescopic winch to rescue Roary and Maxi from mud, gravel, or sand. Plugger can often be heard uttering his catchphrase, "No need to race, Plugger’s on the case!" Model: Mitsubishi L200 (He's often called Lugga in an american version.)
