Do NASCAR cars overheat?
– NASCAR drivers have no air conditioning and spend hours on a hot racetrack behind a burning engine. Keeping racecar drivers cool isn't an option but making sure they don't overheat and consume enough calories is as close as they'll get if they want to win the championship.
Engine coolants are designed to do just that: help limit the temperature of the engine from rising to dangerous levels, especially under the stress of race conditions. In its simplest terms, the coolant absorbs heat building in the engine cylinder heads and disburses it away through the radiator.
The normal operating temperature for a NASCAR Sprint Cup engine varies among teams, but most run in the 230 to 260 degree range.
NASCAR Cars are fitted with cooling systems to prevent driver overheating during a race. Air is pushed into the drivers' helmet and racing suit from a NACA duct near the rear side window this aims to both cool the driver and remove Carbon monoxide. Some drivers also incorporate “air seats” and when required ice packs.
To manage the heat, drivers use a ventilation system to blow air on them through hoses and sit on a bag that pushes cool air up from the seat. Air from the hoses hits the drivers' feet from under the steering wheel and their head from the top of their helmet.
In NASCAR Cup engines, the use of extremely high coolant and oil temperatures (upwards of 270 F and 325 F respectively) increases the effectiveness of the heat transfer from the heat exchangers to the ambient air (higher delta-T).
Crew chiefs and engineers are loathe to use engine power for anything except speed. Air conditioning a racecar would take a lot of energy and the unit would be a lot larger than the one in your passenger car because we're talking about getting rid of a lot more heat.
Randolph says that his team's engines use 100 PSI pressure relief valves, which bring the boiling point up to around 335 F, though he says engine temperature is usually lower than that, and is set not by a thermostat (since there isn't one in these engines), but simply by the vehicle's airflow.
The specialized NASCAR fuel is Sunoco Green E15, a 98 octane, unleaded fuel blend specifically engineered for high-performance engines and race cars. It's called Green E15 because the racing fuel is actually green in color.
526-mile short-track). At the backbone 1.5- to 2.0-mile tri-oval tracks of NASCAR, the engines produce over 850 hp running 9,200-9,400 rpm for 500 miles, 600 mi for the Coca-Cola 600 Charlotte race. The current NASCAR Cup engines curb weight is roughly at 575 lb (261 kg).
Is there AC in NASCAR cars?
“We don't have air conditioners inside our race cars. We do have a little bit of fresh air that we pull from outside the race car that's filtered with carbon monoxide filters, so it is nice to breath at least some clean air, but it's not cold by any means,“ Ragan said.
Race Car Drivers Have Special Cool Suits
They're made from various materials such as cotton or other blends. Race car drivers utilize these cooling suits because it's the best way to reduce overall body temperature. While the air helps cool the interior of the car, the suits cool the driver.
If you slow down the exhaust, you slow down the combustion. There's a real correlation between sound and speed. Historically, racers realized that mufflers made their cars slower. Therefore, mufflers have no place on race cars.
Racetracks can start at 80 degrees and rise to more than 130 degrees by the end of a race.
Because there are no doors on the cars, drivers climb in through the window. The black window net keeps limbs in and debris out.
“Most of the racing in NASCAR is mentally demanding because, number one, the competition is extremely fierce and track position these days is so important. But so is every aspect of it – pitstops, pit strategy, driving the car fast and having a fast car, and then again the competition. The field is so deep.”
Racing & High-Performance Vehicles
Asphalt tracks don't allow glycol-based coolants. Thus, most racers use plain water in their cooling system. Glycol is slippery and creates a hazard if spilled on the track.
Rain tires and windshield wipers have been available for use at road courses in recent years during inclement weather for all three national series. Windshield wipers will not be required to be on the vehicles for the start of the Clash but will be mandated on the cars for the March 12 race at Phoenix Raceway.
Anything over 220 is considered overheating. Some car systems alert the driver to overheating at 221 degrees; others begin this a little higher. But you may operate an engine as high as 250 degrees, or maybe even higher, as long as the engine coolant doesn't boil.
In addition to drivers losing control of their race cars, the visibility for the drivers is greatly reduced in bad weather. With limited visibility comes an increased risk crashing. As a result, NASCAR does not often race during rainy weather, especially when it limits visibility, because it is extremely dangerous.
Why do NASCARs have roof flaps?
The roof flaps deploy when the car spins backward, and the force of the air pushes them up. That creates downforce, which helps keep a car that is spinning out of control at 180 or 200 mph from flying up in the air like a kite.
Why Does NASCAR Only Turn Left? NASCAR cars only turn left in the interest of increasing driver safety and following tradition. Left turns are safer for a left-seated driver. Horse races and track and field races were traditionally run counterclockwise, leading NASCAR to follow suit.
The simple answer is that drivers in NASCAR do not wear diapers. The wearing of them even lends itself to safety hazards. The material composition of a diaper can pose a flammability risk.
Yes, NASCAR racers can drink and eat during a race. Some drivers simply take a bottle of their preferred liquid along for the ride, whereas others opt for a more sophisticated hydration system that involves a pipe that connects a liquid supply to the driver's helmet.
How fast are the NASCAR cars? The average top speed of a NASCAR car is just over 321km/h, or 200mph. Compared to a Formula 1 car, this is quite a bit slower, as they hit speeds of 360km/h (223mph). Indycar – another major American racing series – is faster still, reaching speeds of 380km/h (236mph).
A race car's gas tank holds 22 gallons. The gas comes from a central tank to ensure teams don't add additives. The gas cans used to refill cars hold 11 gallons each and weigh about 70 pounds when full. Racing gas is leaded, 104 octane. Development of an unleaded racing fuel is a year or two away.
Fuel consumption
At race speeds, Cup Series cars get 2 to 5 miles per gallon. Consumption under caution can be estimated at 14-18 mpg, based on comparable engines generally available to the public.
The standard fuel dump can weighs approximately 95 pounds when filled with 12 gallons of racing fuel; A gallon of racing fuel weighs about 6 pounds (the actual weight will vary depending on temperature);
The engines in today's NASCAR race cars produce upward of 750 horsepower, and they do it without turbochargers, superchargers or particularly exotic components.
Anatomy of a NASCAR. It's not an air vent; it's a spot to slip a tool in to make adjustments that affect the way the car handles. One hole is to make adjustments to the springs. A second hole lets you slip a tool in to adjust the track bar.
What are Nascar engine blocks made of?
NASCAR engine blocks are indeed made from cast iron, but not the cast iron you're probably used to. A brief lesson on how you make cast iron. You start with iron, which is a very malleable (meaning easily deformed) material.
The racing fuel is a high-octane blend made exclusively for NASCAR by Sunoco called Green E-15. It's 15% ethanol and unleaded gasoline with a greenish hue, which explains the name, and an octane rating of 98.
How does Burnt Rubbèr smell and does it remind you of anything? Burnt rubber is the sole smell of the racetrack. The smell of the nitro that burns out of our header pipes at over 300 mph, the burning smell of the tires when they strike the asphalt.
Top Alcohol refers to two different classes in professional drag racing: Top Alcohol Dragster and the Top Alcohol Funny Car. Commonly known as "alky" cars, both are akin in design to the premier Top Fuel classes, but less powerful (about 3,500 bhp (2,600 kW; 3,500 PS)).
Crumpled frames and engines are sent to scrapyards like Gordon or Foil's, Inc., in Harrisburg, N.C., where they are flattened, then ripped into hand-size pieces that will be milled back into new steel. And some of that steel can end up back in a race shop.
NASCAR weight slows it down
These stock cars featuring V-8 engines can reach top speeds of up to 200 mph, and can go from 0 to 60 mph in 3.4. seconds.
The first lap was to be run at 5,000 rpm, which is right about 100 mph, with speeds increasing gradually throughout the eight-lap run. By the beginning of the straightaway after the first turn, we were up near the top of the track, about 5 feet from the wall, starting to really percolate.
NASCAR officials will continue to work on the muffler system so it can be used on short tracks and road courses. During the Phoenix test, officials found the addition of mufflers made the chassis and frame components of the car hotter than normal.

The Next Gen car, which debuted last year, has the exhaust come out from both sides of the car instead of just the left side, making it a much louder car than drivers (and fans) were used to hearing. Some drivers said they had to change their earplugs last year because of just how loud the cars are.
Do NASCAR drivers have fire proof suits?
In an effort to enhance safety protocols to protect its most vital asset – the drivers – NASCAR will now require racers to wear various fire-resistant clothing items, including a helmet skirt, socks and underwear. The league had previously only recommended drivers wear such clothing.
The suits are not entirely fireproof, but rather fire retardant for a period of time, allowing an individual to escape an incident or be rescued with minimal injury. Bill Simpson, an innovator in racing safety, estimated in 1993 that a person has "20 to 30 seconds" before a fire suit begins to burn.
A driver's helmet also helps keep his head safe and somewhat cool. It has a hose attached to the back that works as a carbon monoxide filter, and it blows air into the helmet.
If the tracks were completely circular, the drivers would constantly be turning. It's harder to build speed when you're turning, so the stretches of track on the long side of the oval are there to let drivers put the pedal to the metal.
The cars do not have actual headlights to eliminate the risk of glass being broken and covering the track. If glass headlights were to break on the track, it would present a clear danger to the cars and drivers, especially the car's tires.
Race Car Drivers Have Special Cool Suits
They're made from various materials such as cotton or other blends. Race car drivers utilize these cooling suits because it's the best way to reduce overall body temperature. While the air helps cool the interior of the car, the suits cool the driver.
first thing to remember is nascar engines are cooled by water only. antifreeze is not permitted.
NASCAR uses a fuel can type known as a dump can to refuel its vehicles on a pit stop. The dump can is designed to release the fuel it holds into the vehicle within eight seconds. Each fuel can holds 11 gallons, so it takes two full cans to completely refuel a car.
Despite Temperatures reaching up to 130 Degrees F in a NASCAR race car they are not equipped with Air Conditioning Units. The extra weight will result in a loss in handling and speed. To cool drivers Race cars have vents and fans driven by the car's momentum and cooling packs for drivers if needed.
The entirety of these races are spent in the car, so there is no running to the bathroom for the driver to relieve themselves properly. This means that, on rare occasions, NASCAR drivers urinate during a race, but they are forced to do it directly in their fire suits while driving their race car.
How much do NASCAR pit crew members get paid?
Well, NASCAR pit crews are well-compensated for their hard work and dedication. The average salary for a pit crew member ranges from $30,000 to $100,000 per year. This salary can vary depending on factors such as the team's success, the pit crew member's experience, and any sponsorship deals that the team may have.
NASCAR weight slows it down
NASCAR races have the slowest cars among these three series because of the weight of the vehicles, which usually reach around 3,000 lbs. These stock cars featuring V-8 engines can reach top speeds of up to 200 mph, and can go from 0 to 60 mph in 3.4.
Road course races, like this week's at Sonoma, have a 40 mph pit road speed limit. However, NASCAR allows a 5-mph tolerance, so the effective pit road speeds range from 35 mph to 60 mph. As an example, let's consider the pit road loops at Pocono.
“It's usually about 30 to 40 degrees [Fahrenheit] hotter inside the car than the outside ambient temperature,“ said David Ragan, a driver in NASCAR's premier division for 11 years. This means that if it is 90 F and sunny for a Sunday afternoon race, the temperature inside the car can climb over 130 F inside the car.
The specialized NASCAR fuel is Sunoco Green E15, a 98 octane, unleaded fuel blend specifically engineered for high-performance engines and race cars. It's called Green E15 because the racing fuel is actually green in color.
American Ethanol is an integral part of the NASCAR experience. From the Gander RV & Outdoors Truck Series to the Cup Series, your favorite driver competes every weekend with Sunoco Green E15, made with 15 percent American Ethanol.
If rain begins to fall during the middle of a race, the race will be put on hold until the precipitation ends and the track is able to be dried. A passing shower may just lead to a short break in the race, but a persistent, heavy rain could cause the race to be suspended for hours, or even until the following day.
