how long does a top fuel dragster engine last

Titanium can be used to prevent oil spills in the event of a blown rod. [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. [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. This also was the result of the fatal crash at Gateway International Raceway. Beryllium-copper has been tried but its use is limited due to its toxicity. I was wondering the other day about rpqm's. The engine is warmed up for about 80 seconds. 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. Ethanol-blended gas lasts up to three months. Securing the heads to the block is done with aircraft-rated steel studs and stud nuts. BME Top Fuel Dragster Specifications and Component List. Larger bores have been shown to weaken the cylinder block. Seats are of ductile iron. ", "FORGET 8,000 HORSEPOWER ... TOP FUEL IS NOW OVER 10,000 HORSEPOWER! 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"). This also helps prevent pre-ignition, which is often a problem when using nitromethane. 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. A normal street driven engine, lets say 300hp, will have a life of maybe 100-150k miles. 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. 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. 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. It runs in five oil pressure lubricated bearing shells and is driven by gears in the front of the engine. Intake and exhaust rockers are billet. A 4.1875-inch (106 mm) bore with a 4.5-inch (114 mm) stroke are customary dimensions. Crankshafts only last 1-3 runs now, which are $6k each. 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. Top Fuel monsters put on notice: 5,000-hp electric dragster has 8 world records in its sights When you are building an engine with more horsepower, the general rule is that the engine will not last as long. Travelling at 335 mph, how long does it take a Top Fuel dragster to finish a 1000-foot track? Multiply by 4.5 seconds = 600 rpqm. Pistons are made of forged aluminum. The pan is made of titanium or aluminum. The piston is anodized and Teflon coated to prevent galling during the high thrust load operation encountered. This means that a "fueler" engine will provide power over a very broad range from very lean to very rich mixtures. As power increases so does the cost. "50 Years of Funny Cars" in, Front to back: The rear-engine transition (, Ganahl, Pat. - posted in The Nostalgia Forum: When was the last time that a front-engined slingshot Top Fuel dragster competed in a NHRA event? 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. For a given amount of air consumed, this means that an engine can burn 7.6 times more nitromethane than gasoline. The engine has hemispherical combustion chambers, a 90-degree valve stem angle; 4.8 inches (120 mm) bore pitch. 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. Add power increases so does the cost. 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. Q: How long does a Top Fuel piston last? (You can’t buy it, we asked.). 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. Thank you [25], McClurg, Bob. 540. [citation needed]. 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. 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). 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. The 426 Hemi-based engine block is aluminum, as are the supercharger, massive cylinder heads, and rods. 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. "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! That's a power-to-weight ratio of 3.37 horsepower per pound, about 20 times better than the new Z06 Corvette's. Much of organized drag-racing is sanctioned by the National Hot Rod Association. A Top Fuel engine will consume more than 14 gallons of fuel over the entire time from start-up to the finish line. 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 … The plugs are placed in such a way that they are cooled by the incoming charge. 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. 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. 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. There are no water passages in the block, which adds considerable strength and stiffness. 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. That compression of the tire expands the contact patch to almost 250 square inches—larger … Before their run, racers often perform a burnout in order to clean and heat tires. How does a top fuel rail car dragster engine produce 8000 horsepower when the engine is only a 500 ci hemi engine. A key attribute for a Top Fuel engine, as Davin points, was the use of oversized studs as opposed to longer bolts. 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. A 55-gallon drum of nitromethane today costs about $900. Typically four or five runs in our car. They are called "zoomies" and exhaust gases are directed upward and backwards. The long duration spark (up to 26 degrees) provides energy of 950 millijoules (0.23 calth). While others had been developed in the previous decade, it was the first successful one, winning the 1971 NHRA Winternationals. NHRA competition rules limit the engine displacement to 500 cubic inches (8,190 cm3). The pump can flow 100 US gallons (380 l) per minute at 7500 rpm and 500 psi (3,400 kPa) fuel pressure. 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. 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]. Additionally, the burnout applies a layer of fresh rubber to the track surface, which greatly improves traction during launch. 90 degree configuration and run in five conventional bearing shells. Dragsters are limited to a maximum wheelbase of 300 inches (760 cm). 6 seconds. Jon C. 3,214 posts ... Steve Read conducted an impromptu experiment along these lines last year in … “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 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. Q: What goes on in the pits after a typical run? Certain models use a torque sensor incorporated as part of the RacePak data system. * One Top Fuel dragster 500 cubic-inch Hemi engine makes more horsepower than the first 4 rows at the Daytona 500. Typical safety equipment for contemporary top fuel dragsters: full face helmets with fitted HANS devices; multi-point, quick release safety restraint harness; full body fire suit made of Nomex or similar material, complete with face mask, gloves, socks, shoes, and outer sock-like boots, all made of fire-resistant materials; on board fire extinguishers; kevlar or other synthetic "bullet-proof" blankets around the superchargers and clutch assemblies to contain broken parts in the event of failure or explosion; damage resistant fuel tank, lines, and fittings; externally accessible fuel and ignition shut-offs (built to be accessible to rescue staff); braking parachutes; and a host of other equipment, all built to the very highest standards of manufacturing.
