Thus, to attain maximum performance, before each race, by varying the level of fuel supplied to the engine, the mechanical crew may select power outputs barely below the limits of tire traction. Valve retainers are also made of titanium, as are the rocker covers. One of DSR's pit crew mentioned $12k - $35k. This subjects the driver to an average acceleration of about 4.0 g0 (39 m/s2) over the duration of the race and with a peak of over 5.6 g0 (55 m/s2). These superchargers are in fact derivatives of General Motors scavenging-air blowers for their two-stroke diesel engines, which were adapted for automotive use in the early days of the sport. At temperatures over 30˚ Celsius, diesel typically lasts six to twelve months. How is nitrous used in stock cars if the driver has it installed. When Hagerty resident wrench Davin Reckow called Don Schumacher Racing with the idea of doing a Redline Rebuild for one of its Top Fuel engines, we weren’t sure what the answer would be. The block is machined from a piece of forged aluminum. At maximum throttle and RPM, the exhaust gases escaping from a dragster's open headers produce about 900–1,100 pounds-force (4.0–4.9 kN) of downforce. Such is the strength of a top fuel crankshaft that in one incident, the entire engine block was split open and blown off the car during an engine failure, and the crank, with all eight connecting rods and pistons, was left still bolted to the clutch. The connecting rods are of forged aluminum and do provide some shock damping, which is why aluminum is used in place of titanium, because titanium connecting rods transmit too much of the combustion impulse to the big-end rod bearings,[citation needed] endangering the bearings and thus the crankshaft and block. Ethanol-blended gas lasts up to three months. Multiply by 4.5 seconds = 600 rpqm. 540. As such, they, too, lack water jackets and rely entirely on the incoming air/fuel mixture and lubricating oil for their cooling. resulting in cars that may seem substantially less advanced than the average family car. However, while some basic facets of engine configuration are heavily restricted, other technologies, such as fuel injection, clutch operation, ignition, and car materials and design, are under constant development.[6]. Crankshafts only last 1-3 runs now, which are $6k each. Like the original Hemi, the racing cylinder block has a deep skirt for strength. 9,500. The engine power output can also be calculated based upon the car's weight and its performance. [citation needed] Compression ratio is about 6.5:1,[citation needed] as is common on engines with overdriven Roots-type superchargers. For a given amount of air consumed, this means that an engine can burn 7.6 times more nitromethane than gasoline. Thank you The camshaft is billet steel, made from 8620 carbon or S7 through-hardened tool steel or similar. A 55-gallon drum of nitromethane today costs about $900. One of DSR's pit crew mentioned $12k - $35k. Of course, those output figures are extrapolated based on time, speed, distance, and weight, because there isn’t a dynamometer in the world capable of verifying those numbers. Like the cam follower rollers, the steel tip roller rotates on a steel roller bearing and the steel rocker arms rotate on a pair of through-hardened tool steel shafts within bronze bushings. That's a power-to-weight ratio of 3.37 horsepower per pound, about 20 times better than the new Z06 Corvette's. They also mandated enclosed roll cages.[10]. Be sure to check out the full, mesmerizing Redline Rebuild and our detailed explanation video for more information. The International Hot Rod Association, which now sanctions Top Fuel in Australia, dropped the distance in September 2017 after Santo Rapisarda, a car owner who often runs NHRA races in the United States, pushed for the change. The engine used to power a Top Fuel drag racing car is built exclusively of specialized parts, it retains the basic configuration with two valves per cylinder activated by pushrods from a centrally-placed camshaft. 3,000 Depending on the tool, repairs can easily run $75-$150, or in some cases the cost of a whole new piece of equipment when yours can’t be saved. If it was under a hood like a normal car, there'd be at least some insulation to muffle the sound; however, it's completely exposed, and all the engine's workings are right out there -- … They are called "zoomies" and exhaust gases are directed upward and backwards. Since 1955, the association has held regional and national events (typically organized as single elimination tournaments, with the winner of each two car race advancing) and has set rules for safety, with the more powerful cars requiring ever more safety equipment. The plugs are placed in such a way that they are cooled by the incoming charge. [17], They were shortly turning in E.T.s in the low 11s and trap speeds of over 140 mph (230 km/h); at Long Beach on 21 March, an 11.49 pass at 141.66 mph (227.98 km/h) was recorded. After each lap, the entire engine is disassembled and examined, and worn or damaged components are replaced. Top Fuel dragsters are the NHRA's loudest cars, in part because of the way the engine is mounted. The supercharger is slightly offset to the rear to provide an even distribution of air. The engine has hemispherical combustion chambers, a 90-degree valve stem angle; 4.8 inches (120 mm) bore pitch. In recent years, only exhibition races in Martin, Michigan's US 131 Motorsports Park are run as Top Fuel races to the quarter-mile. The rear tire pressure is also heavily regulated by Goodyear Tire and Rubber on behalf of the NHRA, at 7 psi (48 kPa), the absolute minimum pressure allowed. Once inside, the billet steel crank and camshaft are no less imposing. [3][4][5], Like many other motor sport formulas originating in the United States, NHRA-sanctioned drag racing favors heavy restrictions on engine configuration, sometimes to the detriment of technological development. There it earned the #1 qualifier spot (to say he was a proud papa would be an understatement) before being knocked out in the second round. This also was the result of the fatal crash at Gateway International Raceway. BME Top Fuel Dragster Specifications and Component List. As daunting as those engines are given the amount of raw power, at the end of the day they’re generally simple. All components are limited to the number of runs so depending how many reach their limit this run, governs how much this one run will cost. Crankshafts only last 1-3 runs now, which are $6k each. This "oil scraping" also provides a key heat removal step for the cylinder walls and piston skirts, the oil film is renewed as the piston moves upward after BDC. Note that Detroit Diesel did not produce a 14-71. NHRA Top Fuel dragsters are the world's fastest accelerating land vehicles. The intake valve is made from solid titanium and the exhaust from solid Nimonic 80A or similar. He packed up his tools and did his best Tony Schumacher impression by stomping the pedal down and blasting straight to Brownsburg. [16] These cars ran in NHRA's S/FX class, variously defined as "Super Factory Experimental" or "Supercharged Factory Experimental". Add power increases so does the cost. Is it a constant flow or is it staged or what? 91, Carburetor Basics | Kyle’s Garage – Ep.24, Redline meets Barnfind Hunter for our next rebuild | Redline Update. The stoichiometry of both methanol and nitromethane is considerably greater than that of racing gasoline, as they have oxygen atoms attached to their carbon chains and gasoline does not. The laminar flame speed and combustion temperature are higher than gasoline at 0.5 m/s (1.6 ft/s) and 2,400 °C (4,350 °F) respectively. The recipe, despite its lack of diversity, is an effective one; 526 cubic inch Hemi engine, big top-mounted roots supercharger, direct drive transmission, mega fuel systems, huge wings and monster tires. Top fuel dragsters are some of the most powerful machines on the planet, generating power and speed that push against the upper limits allowed by the laws of physics. Off topic, but did anyone notice how long it is between when the engine comes up and the driveshaft moves? Your cost may be lower in the short term with ethanol-laden street gas, but over the long run, you’ll pay more for repairing or rebuilding the degraded fuel system in your small engine. Additionally, after sufficient fuel has been combusted to consume all available oxygen, nitromethane can combust in the absence of atmospheric oxygen, producing hydrogen, which can often be seen burning from the exhaust pipes at night as a bright white flame. The tools aren’t expensive, but they are purpose-built by the team for one job only. I found it astonishing that some of those engines won't last 600 revolutions ! At launch, his Top Fuel dragster can pull 6gs and if all goes well, he passes 330 mph (531 km/h) in around 3.6 seconds. In some cases, teams are required to use technologies that may be decades old,[which?] A key attribute for a Top Fuel engine, as Davin points, was the use of oversized studs as opposed to longer bolts. Exhaust temperature is about 500 °F (260 °C) at idle and 1,796 °F (980 °C) by the end of a run. There are five main bearing caps, which are fastened with aircraft-standard-rated steel studs, with additional reinforcing main studs and side bolts("cross-bolting"). It has twisted lobes and is driven by a toothed belt. [citation needed]. NHRA Top Fuel teams get 75 minutes between rounds to do a complete engine rebuild. A Top Fuel engine will consume more than 14 gallons of fuel over the entire time from start-up to the finish line. “Every team is trying to dump the maximum fuel it can into its motor,” says Davin, “but there’s a very fine line between burning and hydrolocking. The pan is made of titanium or aluminum. They inspect for microfracture after each run to hope for 3 runs. A top fuel dragster accelerates from a standstill to 100 mph (160 km/h) in as little as 0.8 seconds (less than one third the time required by a production Porsche 911 Turbo to reach 60 mph (100 km/h))[1] and can exceed 280 mph (450 km/h) in just 660 feet (200 m). Additionally, the burnout applies a layer of fresh rubber to the track surface, which greatly improves traction during launch. This particular engine lived long enough to earn itself a rebuild, while other less fortunate engines suffer catastrophic failures that force early retirement. 3.6 seconds. The next event was at Bristol where it was #2 qualifier and ultimately went on to win the Wally for the weekend. Certain models use a torque sensor incorporated as part of the RacePak data system. Seats are of ductile iron. A: Barring no failure of any other component, usually we’ll run them about five runs. [21][22], In 1984, Top Fuel was at a low point. The dual valve springs are of coaxial type and made out of titanium. This motor may last a few hundred years before it would need rebuilding or replacement. Some estimates have power outputs of a single blown Top Fuel engine … There's also a split second from when the driver hits the gas and the engine comes up. So when Schumacher invited us to work our magic on one of its beasts at company headquarters in Brownsburg, Indiana, Davin wasn’t about to hesitate while the offer was on the table. Mechanical roller lifters (cam followers) ride atop the cam lobes and drive the steel push rods up into the steel rocker arms that actuate the valves. -The current Top Fuel dragster elapsed time record is 4.441 seconds for the quarter mile. The NHRA also mandated that different rear tires be used to reduce failure, and that a titanium "shield" be attached around the back-half of the roll-cage to prevent any debris from entering the cockpit. [National Dragster]", "Test Shows Top Fuel Nitro Engine Makes Over 11,000 Horsepower", NHRA News: Nitro percentage to be raised to 90 in Top Fuel, Funny Car in 2008 (9/15/2007), Restored Top Fuel Dragsters from the 60s & 70s, NHRA National Hot Rod Association Website, IHRA International Hot Rod Association Website, https://en.wikipedia.org/w/index.php?title=Top_Fuel&oldid=995851358, Articles with dead external links from February 2018, Articles with permanently dead external links, All articles with specifically marked weasel-worded phrases, Articles with specifically marked weasel-worded phrases from November 2018, Articles with unsourced statements from November 2018, Articles needing additional references from July 2019, All articles needing additional references, Articles with unsourced statements from June 2011, Articles with unsourced statements from September 2010, Creative Commons Attribution-ShareAlike License, This page was last edited on 23 December 2020, at 06:10. The oil system has a wet sump which contains 16 US quarts (15 l) of SAE 70 mineral or synthetic racing oil. Since 2015, NHRA regulations limit the composition of the fuel to a maximum of 90% nitromethane; the remainder is largely methanol. ... as the engine wouldn't last any longer . [citation needed]. These Top Fuel engines make 11,000 horses and power the fastest-accelerating drag cars in the world. The engine of a Top Fuel dragster generates around 150 dB[2] of sound at full throttle, enough to cause physical pain or even permanent damage. They are the most famous and recognizable class of drag racing cars, known around the globe. Also different question. Normal ignition timing is 58-65 degrees BTDC (This is dramatically greater spark advance than in a petrol engine as "nitro" and alcohol burn far slower). Of course, between each run the engine received a thorough refresh that included pistons, cylinder heads, a new supercharger belt, and a full tank of specially brewed oil. The calculated power output of these engines is most likely somewhere between 8,500 and 10,000 hp (6,340 and 7,460 kW),[7] which is about twice as powerful as the engines installed on some modern diesel locomotives, with a torque output of approximately 7,400 pound force-feet (10,000 N⋅m)[8] and a brake mean effective pressure of 1,160–1,450 psi (8.0–10.0 MPa). [23] The same year, Joe Hrudka offered a major purse, the Cragar-Weld Top Fuel Classic and "Big Daddy" Don Garlits returned to Top Fuel full-time. And now to the extreme, where a Top Fuel engine is pushing around 7,000 hp, and I read that they have a life expectancy of around 6 seconds. A sound that intense is not just heard, but also felt as pounding vibrations all over one's body, leading many[who?] There are three approved suppliers of these custom blocks. The sidewalls wrinkle as the tire—generally running between 6.0 and 10.0 psi of pressure—shrinks in radius by more than six inches and the tread effectively balls up at the front of the contact patch. The life of an engine of this sort is typically 11–12 runs in a dragster it is completely replaced, but after each of those passes it will be torn down and rebuilt. Top Fuel monsters put on notice: 5,000-hp electric dragster has 8 world records in its sights It has press-fitted, ductile iron liners. Top fuel drag cars are long and narrow, have large rear tires and extremely narrow front tires, and very little sits between the driver and the explosive powertrain. For the purposes of comparison, a 2009 SSC Ultimate Aero TT, which at the time was among the world's most powerful production automobiles, produces 1,287 hp (960 kW) of power and 1,112 lbf⋅ft (1,508 N⋅m) of torque. … Pistons are made of forged aluminum. Beryllium-copper has been tried but its use is limited due to its toxicity. Power output can be increased by using very rich air-fuel mixtures. 180 degree crankshafts have been tried and they can offer increased power. "Winter Heat: '87 NHRA Wnternationals", in, Learn how and when to remove this template message, "The Mag: Drag racing, the loudest sport", "FORGET 8,000 HORSEPOWER ... TOP FUEL IS NOW OVER 10,000 HORSEPOWER! [13] Bob Hansen won Top Fuel Eliminator (TFE) in his A/HR, with a speed of 136 mph (219 km/h). In 2000, the NHRA mandated the maximum concentration of nitromethane in a car's fuel be no more than 90%. Securing the heads to the block is done with aircraft-rated steel studs and stud nuts. [24] By 1987, NHRA Top Fuel Funny Car was drawing twice as many entrants as positions available. In a typical run the engine can consume between 12 US gallons (45 L) and 22.75 US gallons (86.1 L) of fuel during warmup, burnout, staging, and the quarter-mile run. In general 10 injectors are placed in the injector hat above the supercharger, 16 in the intake manifold and two per cylinder in the cylinder head. The rule was changed in 2008 by the National Hot Rod Association following the fatal crash of Funny Car driver Scott Kalitta during a qualifying session at Old Bridge Township Raceway Park in Englishtown, New Jersey. '[citation needed] Before a run, race announcers usually advise spectators to cover or plug their ears. [19], Bob Sullivan's Pandemonium (a '65 Plymouth Barracuda) joined about six other nitro-fuelled early funny cars facing fuel dragsters in the 1965 season. Top Fuel dragsters are the quickest accelerating racing cars in the world and the fastest sanctioned category of drag racing, with the fastest competitors reaching speeds of 335 miles per hour (539 km/h) and finishing the 1,000 foot (305 m) runs in 3.62 seconds. Titanium can be used to prevent oil spills in the event of a blown rod. The fastest class in the National Hot Rod Association (NHRA) drag-racing series, a top-fuel dragster can rocket to 300 mph in less than 4 seconds. How much fuel does a Top Fuel Dragster burn in one .250 mile run? (You can’t buy it, we asked.). Air is fed to the compressor from throttle butterflies with a maximum area of 65 sq in (419 cm2). Top Fuel dragsters are the quickest accelerating racing cars in the world and the fastest sanctioned category of drag racing, with the fastest competitors reaching speeds of 335 miles per hour (539 km/h) and finishing the 1,000 foot (305 m) runs in 3.62 seconds. They have three rings and aluminum buttons retain the 1.156 in × 3.300 in (29.4 mm × 83.8 mm) steel wrist pin. NHRA competition rules limit the engine displacement to 500 cubic inches (8,190 cm3). Because when you tear down a hot engine, studs mitigate thread damage after multiple disassemblies compared to bolts. As power increases so does the cost. While nitromethane has a much lower energy density (11.2 MJ/kg (1.21 Mcalth/lb)) than either gasoline (44 MJ/kg (4.8 Mcalth/lb)) or methanol (22.7 MJ/kg (2.46 Mcalth/lb)), an engine burning nitromethane can produce up to 2.4 times as much power as an engine burning gasoline. The engine is fitted with eight individual open exhaust pipes, 2.75 in (69.8 mm) in diameter and 18 in (457 mm) long. 2225 Minimum weight, in pounds, of a Top Fuel dragster. The fuel tank holds 17 gallons of fuel. Q: What goes on in the pits after a typical run? In the wake of a Gateway International Raceway fatality in 2004, involving racer Darrell Russell, the fuel ratio was reduced to 85%. The ignition system limits the engine speed to 8400 rpm. There are no water passages in the block, which adds considerable strength and stiffness. A 180 degree crankshaft is also about 10 kg (22 lb) lighter than 90 degree crankshaft, but they create a lot of vibration. The life of an engine of this sort is typically 11–12 runs in a dragster it is completely replaced, but after each of those passes it will be torn down and rebuilt. In the ports there are integral tubes for the push rods. softer the compund of the tire, the more grip it has, down side is they don't last long, top fuel dragster tires last only 1.25 miles These are made of steel and fitted with thermocouples for measuring of the exhaust gas temperature. The supercharger must be a 14-71 type Roots blower. These engines are right there flirting with the limits.”. The massive torque channeled through the rear axle shifts the load of the car rearward and tries to twist the tire on its 16-inch beadlock rim. A 4.1875-inch (106 mm) bore with a 4.5-inch (114 mm) stroke are customary dimensions. As the increased engine speed builds up pump pressure, the mixture is made leaner to maintain a predetermined ratio that is based on many factors, especially race track surface friction. The absence of a protective blanket exposes the driver, team and spectators to shrapnel in the event that nearly any irregularity in the induction of the air/fuel mixture, the conversion of combustion into rotating crankshaft movements, or in the exhausting of spent gasses is encountered. The massive airfoil over and behind the rear wheels produces much more, peaking at around 12,000 pounds-force (53 kN) when the car reaches a speed of about 330 mph (530 km/h). At maximum pressure, it takes approximately 1,000 horsepower (750 kW) to drive the supercharger. The 426 Hemi-based engine block is aluminum, as are the supercharger, massive cylinder heads, and rods. This means that a "fueler" engine will provide power over a very broad range from very lean to very rich mixtures. [15] (Nix tried to persuade Chrisman to get Mercury Racing Director Fran Hernandez to allow him to run his Comet's 427 on nitro, as a way to gain leverage on NHRA, so Nix could use nitro himself). The manifold is fitted with a 200 pounds per square inch (1,400 kPa) burst plate. Each con rod has two bolts, shell bearings for the big end while the pin runs directly in the rod. Billet steel crankshafts are used; they all have a cross plane a.k.a. Power outputs which create tire slippage will "smoke the tires" and as a result the race is often lost. Making such high power levels from such relatively limited displacement is a result of using very high boost levels and running at extremely high RPMs; both of these stress the internal components to a high degree, meaning that the peak power can only safely be achieved for brief periods of time, and even then only by intentionally sacrificing components. This is the fastest class in the NHRA drag racing series, and that’s evident by the capability of the cars racing. The engine is warmed up for about 80 seconds. After 100 years the engine will only have 10,000 miles on it. The pump can flow 100 US gallons (380 l) per minute at 7500 rpm and 500 psi (3,400 kPa) fuel pressure. Dynamometers that can measure the output of a Top Fuel engine exist; however, the main limitation is that a Top Fuel engine cannot be run at its maximum power output for more than 10 seconds without overheating or possibly destroying itself explosively. Q: How long does a Top Fuel piston last? A Top Fuel dragster accelerates to over 100 miles per hour in less than one second, burns 1.2 gallons of nitromethane (again, per second) and actually registers on … After the warm up the valve covers are taken off, oil is changed and the car is refueled. This is why we use mileage to rate how long an engine will last. [18] These cars ran in NHRA's S/FX class, variously defined as "Super Factory Experimental" or "Supercharged Factory Experimental". These plugs are fired by two 44-ampere magnetos. "50 Years of Funny Cars: Part 2" in, Wallace, Dave. In late 2015, tests using sensors developed by AVL Racing showed peak power of over 11,000 hp (8,200 kW).[9]. The rockers are of roller tip type on the intake and exhaust sides. This top fuel dragster quiz will amaze you with its raw power. 100. Due to the relatively slow burn rate of nitromethane, very rich fuel mixtures are often not fully ignited and some remaining nitromethane can escape from the exhaust pipe and ignite on contact with atmospheric oxygen, burning with a characteristic yellow flame. While many of the parts look brand new as they go back together, our rebuild showcases a balance of refurbished parts and new. Last NHRA "slingshot" front-engined Top Fuel dragster? The original Chrysler design of two large valves per cylinder is used. to compare the experience of watching a Top Fuel dragster make a pass to 'feeling as though the entire drag strip is being bombed. While others had been developed in the previous decade, it was the first successful one, winning the 1971 NHRA Winternationals. Valve sizes are around 2.45 in (62.2 mm) for the intake and 1.925 in (48.9 mm) for the exhaust. Over time, sediment and gum will form when oxygen reacts with the fuel, so it’s important there’s as little air … At present, final drive ratios higher than 3.20 (3.2 engine rotations to one rear axle rotation) are prohibited, in an effort to limit top speed potential, thus reducing the level of danger. The crew does this in about two hours between rounds. Travelling at 335 mph, how long does it take a Top Fuel dragster to finish a 1000-foot track? The model name of these superchargers delineates their size – the once commonly used 6-71 and 4-71 blowers were designed for General Motors diesels having six cylinders of 71 cu in (1,160 cm3) each, and four cylinders of 71 cu in (1,160 cm3) each, respectively. 1 second ... From the start to finish of a race, how many revolutions will a Top Fuel dragster engine have spun? Why? That compression of the tire expands the contact patch to almost 250 square inches—larger … Haul your horses with this Ferrari 412 pickup conversion, Wrenchin’ Wednesday: Efficient, no-mess grease packing, Chip Foose reimagines the iconic Jaguar E-type, Chip Foose reinvents the 1966 Ford Bronco with street-savvy style, First wash in 40 years: Detailing our Barn Find Chevy with Larry from Ammo NYC | Redline Update, Moving a Ferrari and a Cobra to get to a Triumph and Morgan Plus 8 | Barn Find Hunter – Ep. Dragsters are limited to a maximum wheelbase of 300 inches (760 cm). A: After every run, our engine gets completely torn down, so … Absolute manifold pressure is usually 56–66 pounds per square inch (390–460 kPa), but up to 74 pounds per square inch (510 kPa) is possible. [20], In 1971, Don Garlits introduced the Swamp Rat XIV, a rear-engined Top Fuel dragster. Larger bores have been shown to weaken the cylinder block. When you are building an engine with more horsepower, the general rule is that the engine will not last as long. It was having trouble attracting full sixteen-car fields, leading to cutting back to eight-car rosters, while the International Hot Rod Association dropped Top Fuel entirely. * One Top Fuel dragster 500 cubic-inch Hemi engine makes more horsepower than the first 4 rows at the Daytona 500. Think of a 1916 car engine that is driven only 100 miles a year and put in storage after each use. [citation needed] The first female driver in the Top Fuel category is also the most associated female in the drag racing world, Shirley Muldowney, who won three championships during her career. Any breakthrough or invention that is likely to contribute to driver, staff, and spectator safety is likely to be adopted as a mandated rule for competition. Sign up for the latest automotive news and videos—in short, everything for people who love cars. In 1958, NHRA banned nitro in all categories; the American Hot Rod Association (AHRA) still allowed it, and Fuel Dragsters (FD), Hot Roadsters (HR), and Fuel Coupés (FC): this led to Fuel Altereds (AA/FAs), Factory Experimentals (A/FXs), and (ultimately) Funny Cars (TF/FCs). The ignition system is not allowed to respond to real time information (no computer-based spark lead adjustments), so instead a timer-based retard system is used. Much of organized drag-racing is sanctioned by the National Hot Rod Association. “The team is always looking for efficiency. Dosnt an engine like that only produce horsepower in the hundreds? The ignition system provides initial 60,000 volts and 1.2 amperes. During a nighttime event, the slow-burning nitromethane can be seen to extend flames many feet out from the exhaust pipes. The cylinder heads are machined from aluminum billets. According to the U.S. Energy Information Administration, most gasoline sold in the U.S. is “E10” gas made … At peak power, each 62ci cylinder generates 1,000-plus horsepower, equaling 16 … Oil pump pressure is somewhere around 160–170 psi (1,100–1,200 kPa) during the run, 200 psi (1,400 kPa) at start up, but actual figures differ between teams. While many of the parts look brand new as they go back together, our rebuild showcases a balance of refurbished parts and new. This is made possible by the fact that, in addition to fuel, an engine needs oxygen in order to generate force: 14.7 kg (32 lb) of air (21% oxygen) is required to burn one kilogram (2.2 lb) of gasoline, compared to only 1.7 kg (3.7 lb) of air for one kilogram of nitromethane, which, unlike gasoline, already has oxygen in its molecular composition. chassis: BME #02: engine displacement: 500 cubic inches: power: 10,000 horsepower at 8200 rpm: weight: 2350-lbs: wheelbase: 300 in. "50 Years of Funny Cars" in, Front to back: The rear-engine transition (, Ganahl, Pat. Image: Auto Imagery. Thus, the currently used 14-71 design can be seen to be a huge increase in power delivery over the early designs, purpose-built for the GM Detroit Diesel truck powerplants. Complaints from teams in regards to cost, however, has resulted in the rule being rescinded starting in 2008, when the fuel mixture returns to 90%, as NHRA team owners, crew chiefs, and suppliers complained about mechanical failures that can result in oildowns or more severe crashes caused by the reduced nitromethane mixture. [11], Independent drag strips, not NHRA sanctioned, offered venues for the fuel racers. [14], Jimmy Nix, who previously ran a Top Gas dragster; Jim Johnson, who ran a Dodge Polara stocker, and who had won the B/SA title in 1963; Jim Nelson; and Dode Martin pioneered TF/FC. [25], McClurg, Bob. The shortening of the distance was used by the FIA at some tracks, and as of 2012 is now the standard Top Fuel distance defined by the FIA. 0.3 seconds.
