BME Top Fuel Dragster Specifications and Component List. * Under full throttle, a dragster engine consumes 11.2 gallons of nitro methane per second; a fully loaded 747 consumes jet fuel … 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 … resulting in cars that may seem substantially less advanced than the average family car. 3,000 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). I found it astonishing that some of those engines won't last 600 revolutions ! Image: Auto Imagery. [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. 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. In some cases, teams are required to use technologies that may be decades old,[which?] NHRA Top Fuel teams get 75 minutes between rounds to do a complete engine rebuild. [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. Valve retainers are also made of titanium, as are the rocker covers. 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. Typically four or five runs in our car. How is nitrous used in stock cars if the driver has it installed. 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. [12] Smokers Car Club hosted the first U.S. Fuel and Gas Championship at Famoso Raceway in March 1959. Measuring the power output of a top fuel engine directly is not always feasible. This particular engine lived long enough to earn itself a rebuild, while other less fortunate engines suffer catastrophic failures that force early retirement. -The current Top Fuel dragster elapsed time record is 4.441 seconds for the quarter mile. (You can’t buy it, we asked.). 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. Nitromethane also has a high latent heat of vaporization, meaning that it will absorb substantial engine heat as it vaporizes, providing an invaluable cooling mechanism. [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. 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. "50 Years of Funny Cars" in, Front to back: The rear-engine transition (, Ganahl, Pat. Both during the teardown and reassembly, Davin was impressed with the specialty tools and rigorous strategy that Don Schumacher employs to made each task just a bit easier and faster. “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 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. Securing the heads to the block is done with aircraft-rated steel studs and stud nuts. Air is fed to the compressor from throttle butterflies with a maximum area of 65 sq in (419 cm2). 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. 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. A Top Fuel engine will consume more than 14 gallons of fuel over the entire time from start-up to the finish line. Top Fuel monsters put on notice: 5,000-hp electric dragster has 8 world records in its sights The plugs are placed in such a way that they are cooled by the incoming charge. The BME Top Fuel Dragster backing up to the starting line after a burnout at Houston in 2016. Add power increases so does the cost. These Top Fuel engines make 11,000 horses and power the fastest-accelerating drag cars in the world. 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"). Cracking open the 500-cubic-inch V-8 was more of a lesson in heavy-duty parts. 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 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. Additionally, the burnout applies a layer of fresh rubber to the track surface, which greatly improves traction during launch.
