Both engines are built by Cosworth in Torrance, California, under the guidance of newly appointed technical designer Wayne Merry (formerly of Cosworth in Worcester UK). 1991 saw the introduction of customer units, two specifications behind their works equivalents. A Jaguar-badged version of the HB was developed by Tom Walkinshaw Racing to the tune of 650 bhp at 11,500 rpm for sports car racing, fitted to the extremely successful Jaguar XJR-14. The CA2010 is the same 2.4-litre V8 base of the CA2006 used by Williams, but has been re-tuned for the then-mandated 18,000 rpm limit required on all engines, down from its original 20,000 rpm implementation. We have available various spare parts for Cosworth V8 engines: DFV, DFY, DFZ and DFW - Heads used both DX SX. The following is the list of initial products, with cylinder heads modified, but not originally designed by Cosworth, on Ford Kent engine cylinder blocks. Models, plaster styling studies and paper projects were all that most had to show. In order to produce a higher power at higher rpm, a completely new 2,992 cc (182.6 cu in) (89mm x 48.1mm) JD 72° V10 was designed for 1996, which produced about 670 bhp at 15,800 rpm, and used by Sauber Formula One team. Further evolutions of the YB included a reduced-emissions road version, as well as the block used in the Escort RS Cosworth (which used the Sierra floorpan). After Duckworth decided he did not want to be involved with the day-to-day business of running a growing company, he sold out the ownership to United Engineering Industries (UEI) in 1980, retaining his life presidency and day-to-day technical involvement with Cosworth, and becoming a UEI board director; UEI was a group of small- to medium-sized technology companies, which was taken over by Carlton Communications in 1988 – Carlton was primarily interested in some of the audio-visual companies in the UEI portfolio, and Cosworth was a poor fit with these; a new buyer for the company in the engineering/automotive sector was sought, and the traditional engineering company Vickers plc bought Cosworth in 1990. Please re-enable javascript to access full functionality. The YB series of 1,993 cc (121.6 cu in) engines are based on the older inline-4 Pinto engine block,[16] and were introduced in the road-going Ford Sierra RS Cosworth in 1986 with 204 PS (150 kW; 201 bhp). GMA T.50 . The domination of this engine was absolute as long as these regulations lasted until 1968. With Haas Lola not competing in 1987, Benetton, having lost the use of the 4 cylinder BMW engines when the German giant pulled out of Formula One, signed with Ford to race their V6 for the season. In 1995, with a new version of the Scorpio, it was upgraded with a wider torque spread and higher power – to 204 PS (150 kW; 201 hp), from a variable intake system and reprofiled cams. The 2004 model of the XFE had a rated power of nominal 750 horsepower (559 kW; 760 PS) at 1,054 mmHg (intake boost pressure), and a maximum power of 800 bhp (597 kW; 811 PS) at 1130 mmHg (during Push-to-Pass). 1,500 hand-built Cosworth Vega engines were simply scrapped for lack of demand. There was even a one-off 785 cc version built by Cosworth employees Paul Squires and Phil Kidsley; fitted with a Lysholm supercharger it was installed in a Brabham BT28 Formula 3 chassis and competed in the British Hill Climb Championship as the Brabham-Lysholm.[14]. It was the year before the McLaren F1 came on the scene. Jones and teammate Patrick Tambay captured the Ford V6 turbo's first ever points when they finished 4th and 5th respectively in the Austrian Grand Prix, with Jones backing up in the next race in Italy with a 6th-placed finish, the final points the engine would gain in 1986. The 2004 XFE maximum speed was 12,000 rpm (rev limited) and torque of 490 N⋅m (361 lbf⋅ft). Cosworth's EA racing version was not successful due to engine block structural failures. This success wasn't just forged on the track, however, with Cosworth part responsible for some road-going icons, too . It won a record 155 World Championship races, the last being Detroit in 1983, powering a Tyrrell driven by Michele Alboreto. One was campaigned in the CanAm series in 1978 in the Osprey SR-1, built and driven by Dan Hartill. Chevrolet later produced a heavy-duty 'off-road' block with thicker walls to better withstand the racing application, but by that time Cosworth had moved on. DFV/DFZ/DFR replacement was designed by Geoff Goddard to result in 3,498 cc (213.5 cu in) (96 mm x 60.4 mm) HB V8, which was introduced with the Benetton team midway through 1989 making its debut at the French Grand Prix, and won the Japanese Grand Prix that year (Benetton used both the original HBA1 and the development HBA4 in 1989). In Max Mosley's letter following the withdrawal of Honda from Formula One in December 2008, it was announced that Cosworth had won the tender to provide a standard engine to any interested participants. The advent of the AWD turbo Audi Quattro gave the rear-wheel-drive, normally aspirated 190E rally car no chance of being successful and the competition car was stillborn. Got a Europa, preferably in black and gold JPS livery, and a shoehorn? It appears to me that BMW are the only manufacturer keen on implementing F1 technology into their roadcars. The Methanol-fuelled engine used a steel crankshaft and aluminium alloy pistons. As around 4 months had been lost in trying to get the 4 cylinder engine to work, Ford and Cosworth's plan for the engine to debut with Haas Lola in 1985 was pushed back to the 1986 season. Experimental version of FVA to aid DFV development : FVC: 1969: 1790cc: 235 Bhp. [25] Several other engine changes were made, notably the removal of the calibrated "pop off valve" designed to limit turbo boost pressure, replaced by engine electronics. The longer stroke SCB was built to compare against the 1,498 cc Mk.XVI, and upon proving its superior power against the Mundy-designed two-valve crossflow DOHC head, it acted as the benchmark for the development of FVA to measure the benefits and shortcomings of a four valve crossflow DOHC design. You can see the Espace there. the camshaft carrier was cast integral with the head itself. Although no DFV-engined road cars were built, there was no shortage of ‘if only’ proposals. It was exclusively used by the Sauber team, whose biggest success of the year was Heinz-Harald Frentzen's third place at Monza. You currently have javascript disabled. The XF was developed for the 2000 season to replace the XD, and was chosen as the spec engine for the Champ Car World Series in 2003. Winning 167 races in a career lasting over 20 years, it was the product that put Cosworth Engineering on the map. The first Cosworth-designed cylinder head was for SCA series; with a single overhead camshaft (SOHC) reverse-flow configuration, similar to the Coventry Climax FWE engine. - Connecting rods and new, with different sizes and lengths. This was surpassed one year later by Rubens Barichello's sensational second place, again at Monaco, which was the first points finish for the newly formed Stewart Grand Prix team. The last was the Detroit Grand Prix in 1983 in a Tyrrell driven by Michele Alboreto. Starting this year, Ford uses Cosworth for the engine names, Minardi used the CK2004 (CR-3L) engine during the first 3 races of the season where the team used the old, This page was last edited on 5 March 2021, at 17:06. that Renault built for promotional purposes with their F1 engine. Originally posted by Viss1 And the new Enzo/F60 goes a few steps further with F1-inspired steering wheel and aero tricks. [citation needed] The 190E 2.3-16 became the basis for privateer Mercedes entries into the DTM from 1988. The Stewart Grand Prix team effectively became the Ford works team, and used Cosworth CR-1 engines from its first season in 1997, which was a much lighter version of VJM, ultimately reaching 770 bhp at 16,500 rpm by 2001. Racing versions of the RS Cosworth were developing around 370 hp (276 kW; 375 PS),[17] but with the small Garrett T3 turbo on the cars reliability was a problem. Cosworth experimented with turbocharged BD derivatives, before settling on an all-new turbocharged 1,500 cc (91.5 cu in) V6 engine to be badged as the Ford TEC (internally it was known as the GB-series). This newly found security enabled the company to distance itself from the Lotus Mk.VII and Elan optional road engine assembly business, and allowed its resources to be concentrated on racing engine development. Cosworth solidified its association with Ford in 1969, by developing a double overhead camshaft (DOHC) 16-valve inline four-cylinder engine for road use in the Ford Escort. Later in 1986, a 2137 cc version was created by Brian Hart using a bespoke aluminium block and a large intercooler for RS200 Evolution, just as Group B was cancelled by the FIA. It appears to me that BMW are the only manufacturer keen on implementing F1 technology into their roadcars. The latter version's severe lack of reliability caused it to fall out of use by 1985. Engines were sent by the race teams to Cosworth for the rebuild. 1993 saw the customer deal extended to McLaren who had lost the use of their Honda V12 engines after 1992. Does anyone know if some ambitious gear-head has ever stuffed a Cosworth DVF or similar F1 engine into a road car. Duckworth shelved the car. The DFX, a turbocharged version of the DFV, was developed privately by the Vels Parnelli Jones team for the 1976 USAC season. In freezing, snowy conditions (−6° Celsius) at approximately 10 AM, the V6 turbo, running a conservative 2.5 BAR boost setting, ran cleanly although the engine management electronics developed by Motorola in the United States and Cosworth had not yet been finalised and the engine ran with the same electronics that were used on the dynamometer. We’ve pushed the boundaries developing the #engine for the @PlanetGMA T.50s Niki Lauda. MAE used one barrel of a two barrel Weber IDA downdraft carburettor with the other barrel blanked off. Community Forum Software by IP.Board. Flat top pistons delivered the 10.5:1 compression ratio. BDD and BDM engines were also prominent in the Australian Sports Car Championship during the 1980s, winning the 1987 championship. This resulted in the DFV, which dominated Formula One for many years. Cosworth became involved in the project soon after, and the engine was known thereafter as the DFX. The engine made its Formula One debut with Jones driving the Lola THL2 at the 1986 San Marino Grand Prix, the third round of the 1986 season (for the opening two races in Brazil and Spain, the team used their 1985 car, the Hart 415-T turbo powered Lola THL1, while Tambay also drove the THL1 at Imola). A racing version was also available for a short time – FBE – with an individual throttle butterfly for each cylinder. A V12 like no other! The rated life of the engine was 1,400 miles (2,300 km) between rebuilds. I think a Lotus Europa might make a good starting point for a sort-of period correct DFV street rocket. [23] First units were ready and shipped to teams in mid-January for fitting 2 weeks prior to first track testing for the year.[24]. By 1993, the factory HBA8 V8 engine used by Benetton was producing approximately 700 bhp (522 kW; 710 PS) at 13,000 rpm. This had a long development history dating back to the 1984 British Grand Prix at Brands Hatch where Cosworth and Ford's competition department agreed to build a new turbo engine to replace the outdated DFV / DFY series. This engine featured 16 valves operated by twin overhead camshafts driven by a train of 9 gears. The Nostalgia Forum bunch would be worth trying for more definitive answers. The DFL for endurance racing was developed for the 1982 season to replace the DFV. The Ford Sierra Cosworth R500 touring car was first introduced in 1987. The turbo charged 1778 cc BDT was created in 1981, which powered the never-raced RWD Escort RS1700T. This engine dominated the category until 1971, and was also used in sports car racing in 1.8 Litre form as the "FVC". A V12 like no other! It won a record 155 World Championship races. For his pole position lap at the 1992 Bathurst 1000, Australian driver Dick Johnson (whose team since 1988 had a reputation for having the fastest Sierras in Group A racing anywhere in the world) was reportedly running a special qualifying engine that was producing close to 680 hp (507 kW; 689 PS) in his RS500. Until 1962, Costin worked on Cosworth projects in his private time, while being active as a key Lotus engineer on the development of Lotus 15 through 26 (Elan), as well as leading the Team Lotus contingent at foreign races, as evidenced by the 1962 Le Mans Lotus scandal. The Cortina Crossflow block was also the basis for the FVA (four valve Type A), an F2 engine introduced in 1966, and developed under the same contract as the DFV, for the new 1.6-litre engine rules. Currently, they have Supervan 3, a Transit based on Focus WRC mechanicals. This included wins in the five major races, the Spa 24 Hours held at Spa-Francorchamps in Belgium, the Bathurst 1000 at Mount Panorama in Australia, the RAC Tourist Trophy at Silverstone in England, the Wellington 500 street race in New Zealand, and the InterTEC 500 at Fuji in Japan. The legendary Ford Cosworth DFV (Double Four Valve) V8 engine is, by a mile, the most successful F1 racing engine of all time. ‘DFV’ standing for ‘Double Four Valve’ because of the presence of four valves per cylinder and ‘Double’ due to the fact that it was the 8-cylinder evolution of … Models, plaster styling studies and paper projects were all that most had to show. [citation needed], The request was a huge surprise for Cosworth, and the original brief for a 320 bhp engine based on the 136 bhp Mercedes M102 2.3-litre SOHC 4-cylinder engine was duly passed to Mike Hall, who "drew the famed DFV and BDA engine". However, the distance between the two camshafts and the valve inclination angle were larger than on DFV for the series. Long-stroke FVA for Under 2 litre sports cars… I suspect it was little more than a space frame with the Espace body as it was mid/rear engined and I don't believe it was road legal. See more ideas about engineering, technical drawing, race engines. The naturally aspirated #V12 weighs just 162kgs and revs to 12,100rpm – that’s more power than the T.50. [citation needed], Cosworth's involvement with Mercedes-Benz came with moves in the mid-1980s from the German manufacturer to re-enter motorsport after retiring from direct factory participation after the tragic 1955 Le Mans crash which killed 80 spectators. The various colour cam covers that distinguished each version were as follows: Red: YBB (Sierra Cosworth 2wd, both 3-door and Sapphire), YBD (Sierra RS500), YBJ (Sierra Sapphire 4wd, non cat); Green: YBG (catalyst equipped 4x4 Sierra Sapphire Cosworth); Blue: YBT (large-turbo Escort Cosworth); Silver: YBP (small-turbo Escort Cosworth). Ford expected a minimum of 400 Hp from the new Cosworth engine; that figure was exceeded, with the engine producing 420 Hp in the first test run. The T.50 engine produces the highest power density of any naturally aspirated road car engine ever made – 166PS-per-litre. What Duckworth is describing is one of the greatest engines in Formula 1 history and his 1966 creation – the Cosworth DFV. It exploited a narrower 75° vee-angle rather than the 90° used in the DFV series, and was originally rated at approximately 630 bhp (470 kW; 639 PS). The larger displacement FVD was designed and released for endurance racing in 1975, that displaced 1,975 cc (120.5 cu in) on the aluminium block developed for BDG. I think that was fitted with a Rover V8, so a DFV would have easily fitted. Projected first year sales of the Cosworth Vega had been 5,000. Ferrari never used a Cosworth engine. During the early ‘60s, regulations for F1 were changing and the then-current 1.5-litre engine was to be replaced with a larger 3.0-litre capacity. The HB was developed into 3,498 cc (213.5 cu in) (100 mm x 55.7 mm) EC V8 for the 1994 season. I saw the Espace F1 in action a few years back. What else could you want! Originally posted by freq019 BMW is talking about putting a V10 into the new 6-series, possibly only in the M version. [28] All WAA 2.3-16 engines were built in the Cosworth factory with the heads being produced by the Coscast method. Cosworth is well known in the automotive world and not just for road-going concerns but for motorsports as well. The naturally aspirated #V12 weighs just 162kgs and revs to 12,100rpm – that’s more power … The engine stopped being used on new cars in 1997, with the Focus WRC and road-going Focus RS instead relying on Zetec designs. The camshafts were driven by a toothed belt developed for Fiat 124, hence the name BDA, literally meaning "Belt Drive, A type". Does anyone know if some ambitious gear-head has ever stuffed a Cosworth DVF or similar F1 engine into a road car. I did a road legal racecar to FiA GT regs. One of the most successful and longest-lived projects of Cosworth has been its CART / Champ Car engine programme. I'll look for it. Two years later, the BDA series was adopted for Formula 2; first came the 1790 cc BDE, then the 1927 cc BDF eventually reaching a maximum of 1975 cc BDG in 1973. Cosworth has collected 176 wins in Formula One (F1) as engine supplier, ranking third with most wins, behind Ferrari and Mercedes.[3]. The first 4-cylinder test engine was so badly damaged that it actually changed the shape of the engine block to the point where the crankshaft would not move- the engine was simply not designed to be turbocharged. In addition to the above, Cosworth designed and provided the assembly work for Lotus Elan Special Equipment optional road engines with special camshafts and high compression pistons. In race tune they finally produced around 462 bhp (345 kW; 468 PS) at 9000 rpm and 300 ft-lb of torque (407 Nm). A real success was achieved with the next gear-driven double overhead camshaft (DOHC) four-valve FVA in 1966, when Cosworth, with a help from Chapman, convinced Ford to purchase the rights to the design, and sign a development contract – including an eight-cylinder version. All rights reserved. This engine retains the standard crankshaft, and has a different cylinder head. For the 1995 season, the F1 engine regulation changed to 3 litres, and the EC's bore and stroke were changed to 94mm x 53.9mm, resulting in 2,992 cc (182.6 cu in) ECA, which was introduced at about 600 bhp, and developed to 610 to 630 bhp at 14,000rpm. The aluminium and iron turbo housing ran a boost of 5.9 psi at sea level (= boost of 12 inches of mercury which is 41.5 inches of mercury absolute). Although World Championship races held in 1952 and 1953 were run to Formula Two regulations, constructors who only participated during this period are included herein to maintain Championship continuity. When the company was founded in 1958, Duckworth left Lotus, leaving Costin (who had signed a term-employment contract with Chapman) at the company. Currently, they have Supervan 3, a Transit based on Focus WRC mechanicals. The GA or GAA was commissioned by Ford in May 1972, when Ford realised that the Cologne V6 based Weslake OHV V6 engines used in their Capris which competed in the European Touring Car Championship had been modified to the point that no more performance could be extracted from them. Here is a link to a judd v10 engined Dome supercar, I can't seem to find the book right now but I remember seeing a Lotus seven fitted with a DFV and used as a hill climb car, or possibly a "Super Sports" car in the UK. Over the next few years Ford had increased its involvement with the Stewart team, and finally bought the team, renaming it Jaguar Racing for 2000. The Champ Car World Series imposed a rev limit of 12,000 rpm down from the over 15,000 rpm of 2002. Saw it a few years ago actually. While designed as an F1 engine, the DFV was also used as in endurance racing, although its flat-plane crank design led to destructive vibrations putting stress on devices surrounding the engine, especially the exhaust system. The DFZ was produced as an interim model, but in 1988 Cosworth created the DFV's final evolution, the DFR, which soldiered on in F1 with smaller teams until 1991, scoring its last points – including a pair of second places by Jean Alesi – with Tyrrell in 1990. Quarter Scale Engines & Supplies, RC products Shipped worldwide. The intake ports and the oil scavenge pickup for dry sump lubrication were canted 25 degrees, so they faced straight up and down, respectively, when the engine was mounted 25 degrees from vertical to the right for a lower centre of gravity. Changes includes a billet crankshaft, barrel throttle bodies, new cylinder head with larger valves, pistons, con rods and camshafts.
