New Limited Super Stock in the UK

The Brutus Pulling Team from Buxton in Great Britain, together with the CDH Pulling Team from Bernay in France have built a new 7700lbs / 3.5t IH component limited super stock tractor during the last winter of 2018 / 2019. After almost 4 years in the 4.5t farm stock / super sport division, the British team around Stephen Charles decided to build a new limited super stock tractor on component base. Stephen Charles built his first puller a Fordson Major when he was 16 years old but he never used it.
But Stephen started properly with pulling in 2007 on some local brush pulls in Great Britain with a Leyland stock tractor. He competed for many years on those brush pulls before he decided to make the next step in the sport. At the end of 2014, Stephen purchased the 4.5t IH super sport tractor called "Brutus" from the Netherlands.
After that, the IH machine received a new paint job and a new look. The tractor kept the name "Brutus" and Stephen registered the super sport ride for the BTPA British Tractor Pulling Championship. In 2015, the Brutus Pulling Team competed on all British Championship rounds, at the Euro Challenge in Made, the Netherlands and also at the European Championship in Brande, Denmark.
During that time the Brutus Team also met at the Made's Powerweekend in the Netherlands the meanwhile late Bram de Pijper of the European Maid Pulling Team from Vierpolders in the Netherlands. And then talk began about a new tractor on alcohol fuel.   
At the beginning of 2018 came the possibility to buy the old European Maid of Bram de Pijper.
At the same time, the European Maid Pulling Team worked on its new Case IH Optum 300 component super stock project. After a short negotiation, Stephen decided to purchase the old component super stock tractor from them. The old European Maid has a homemade steel wedge frame with a van der Waal Pulling Parts 2 bar chrome-moly roll cage, a homemade hydraulic steering with a custom-built steering wheel, homemade wheelie bars, a custom-built sheet metal rear end and an IH 3688 sheet metal hood. Because of the lack of experience to build an alky burner engine and the less time (Stephen has his own transport business) he decided to talk with Guy de Hoef of the CDH Pulling Team from Bernay in France at the tractor pull in Great Eccleston, England in 2018.
The Belgian made him an offer to build the tractor ready to run for him for the 2019 season. After that Stephen decided to let build the tractor by the CDH Pulling Team. During the rebuilt in France, the old European Maid received some changes on the chassis. The old front axle was replaced by a new one, new steel wheelie bars were built and the front end of the chassis like the weight brackets were completely new rebuilt. Also, the rest of the weight brackets were replaced by new ones. After all the sheet metal and welding work was done, the tractor received a new paint job. The paint job was done by the CDH Pulling Team himself in the company called ''AGNP Chaudronnerie'' of Guy and Nick de Hoef. At AGNP Chaudronnerie also were made all the sheet metal work and welding work on the tractor.
After the paint job was done, the IH tractor was again completely built up and received a new Kirkey Racing driver seat with a 4 point harness from the USA, because the machine was sold without a driver seat.
The IH 3688 sheet metal hood and the custom-built sheet metal fenders were not changed on the tractor. The IH 3688 stock tractor for the field was a 2 wheel drive machine which was built in the International Harvester Company plant in Lake Forest, Illinois in the USA from 1981-1985.
The tractor was powered by a naturally aspirated 6 cylinder IH D 436 engine with a displacement of 7.1l / 436 cui on diesel fuel. The D 436 power plant made 115 hp with a maximum torque of 427Nm at 1700rpm.   
The new vinyl graphics on the tractor were done by the company called "High Peak Signs" from Buxton in Great Britain.
The custom-built sheet metal rear end in the limited super stock tractor has a Rockwell aluminum center section with a needle bearing Rockwell SQHD diff, a Rockwell ring and pinion gear, custom-built plug axis by van der Waal Pulling Parts, Franklin billet aluminum planetaries carrier housing with Franklin planetaries and van der Waal Pulling Parts billet brake calipers with laser-cut steel brake discs. The Tractor also has an SCS reverser, a custom-built steel driveshaft and a 5 disc Van der Waal Pulling Parts centrifugal clutch with a Browell aluminum bell housing. All the driveline parts on the limited super stock were taken over of the old European Maid. 
For an optimum grip on the British and European pulling tracks, the Brutus Pulling Team purchased a set of new uncut 24.5-32 Firestone Puller 2000 HP tires on used Midwest aluminum rims. The new puller tires were purchased from the John Deere Pulling Team in Thy, Denmark.
The new Thunderstruck is powered by a turbocharged 6 cylinder IH DT 466 with 8.3l displacement on alcohol fuel.
The IH DT 466 (466cui) engine is a line of a mid-range inline-6 cylinder diesel engine which was produced by the International Harvester Company mainly for farm and construction equipment from 1973-1985. Later the engine was built by the Navistar International Corporation primarily for medium-duty truck and bus applications such as school buses from 1986 until 2004 in Lisle, Illinois, USA. But why was the 466 engine also built under the company name Navistar International Corporation?
International Harvester fell on hard times during the poor agricultural economy in the early to mid-1980s and the effects of a long strike with the UAW over proposed work rule changes. IH's new CEO, Donald Lennox, directed the management organization to begin exiting many of its IH's historical business sectors in an effort to survive. Some of the sales of profitable business endeavors were executed to raise cash for short-term survival, while other divisions were sold due to lack of immediate profitability. During this period of questionable economic survival, in an effort to raise needed cash and to reduce losses, the management team led by Mr. Lennox at IH shed many of its operating divisions: Construction Equipment Division to Dresser Industries; Solar (gas turbines) Division to Caterpillar; Cub Cadet (lawn and garden equipment) to MTD Products and, lastly, the Agricultural Division to Tenneco, which merged it with their J.I. Case subsidiary. The Scout and Light Truck Parts Business was sold to Scout/Light Line Distributors, Inc. in 1991.
After the Agricultural Division sale in 1985, all that remained of IH were the Truck and Engine
Divisions. The company rechristened itself on February 20, 1986 to Navistar International Corporation. (The International Harvester name and IH logo were assets of the Agricultural Division and consequently were part of the sale to Tenneco, the IH name and logo are still in use, having been incorporated into the Case IH brand name). Navistar still uses the "International" brand in its diesel engine and truck product lines, and the brand name continues on in product lines of Navistar International's International Truck and Engine Corporation subsidiary.
But back to the IH tractors. The 466 power plant was used in the farm tractors like the IH 4366, the IH 3588, the IH 5288 and the IH 7488. The first version of the turbocharged 466 in the IH 4366 had 230hp at 2600rpm.
The big machine was built between 1973 and 1976 in the IH plant in Rock Island, Illinois. During the building period from 73-85 under the International Harvester Company, the engine was further developed, improved and the power was increased. In 1979 was the DT 466B version with 152hp introduced into the IH 3588 tractors. But only 2 years later in 1981, the second B version was introduced. The water-cooled turbocharged engine received an Intercooler and was further improved compared to the previous version of the DT 466 and 466B. The Intercooled B version for the tractors was built with horsepower ratings ranging from 180 hp to 238 hp.
The 238 hp engine was built for the IH 7488 (only 16 of this type were built). It was the last big tractor which was built by the International Harvester Company before the agricultural division was sold to Tenneco Inc (J.I. Case) in Lake Forest, Illinois in 1985.
Back to the engine of the new Thunderstruck limited super stock. Everybody knows the original engine on diesel fuel has far too less horsepower for limited super stock pulling, so the only way was to make a lot of changes on the power plant and convert the engine into an alky burner with a much bigger turbocharger.
The completely new rebuilt power plant received a bored up IH 466 cast iron stock engine block with Darton billet steel sleeves, a modified IH 436 stock crank with billet aluminum rods and pistons by van der Waal Pulling Parts, a revised and flowed IH 466 cylinder head with bigger valves and better valve springs from HMT Power Parts from the Netherlands, a custom-built valve cover, a custom-built steel camshaft from Patrice Beaudry from Canada, a homemade aluminum intake manifold, a billet Holset HX 82 turbocharger with intake impeller wheel, a homemade exhaust manifold, a VSP (Veldhuizen Special Product) alcohol fuel system with a VSP fuel pump, a Aviaid oil pump, a homemade aluminum oil pan, a homemade fuel tank, a MSD 8 Plus ignition and a AiM Sports data logger.
The turbocharged 466 engine on alcohol fuel should make around 2000-2500hp with this setup.
The new Thunderstruck had its maiden voyage at the Euro Cup round in Bernay, France at the beginning of June 2019. It wasn't great premiere for the new limited super stock, the new engine ran well but clutch troubles made no pull in front of the French crowd possible. After the clutch problems were solved the tractor ran with the support of the CDH Pulling Team pretty well during the rest of the season and the whole Brutus Pulling Team learned a lot about how the new alcohol system works on the IH engine.
The Brutus Pulling Team have planned to compete in the British Championship and on some European Pulling events outside of the UK in 2020.
