Small "formulas"
After Brabham retired from this company, Judd was hired to develop a Formula 2 engine for the team of Ron Toranak - Ralt.
After the abolition of Formula 2 in late 1984, Judd continued to develop new engines for Honda. The first model was the Judd AV - Turbo V8 , which was created for Champ Car . This engine was first used in mid-1986 by Galles Racing by Jeff Brembham. First, the engine was named Brabham-Honda, winning 4th place on the Michigan 500. In 1987, the engine was used in the Indy 500 . Brembam finished second in Pocono and Road America , as well as 3rd in Miami.
The engine was famous for its reliability and fuel efficiency (especially in racing for 500 miles). Nevertheless, he lacked horsepower, and Ilmor engines looked much better on his background.
In 1988, Truesports with Bobby Reichall became the main team, and the name Honda disappeared that year. Reich had an advantage in engine reliability, which allowed him to finish 4th in the Indy 500 and 2nd in Michigan. Then he managed to win the first and last victory in Pocono 500. 10 finishes in the top ten allowed him to take 3rd place at the end of the championship. In the early 1990s, Judd continued to develop improved versions of Judd AV β one of them was BV , and moreover, atmospheric. This engine became the base for the F-1 engine - CV.
KV
After leaving Formula One, Judd returned to Formula 3000 in 1995, creating for her a three-liter V8 KV engine. All teams used Judd engines, although Zytek set the task of servicing 80 engines after they were built. Judd ceased development of engines when Formula 3000 ceased to exist - in 2004. Later, Zytek used these engines in the A1 GP in 2005.
Formula 1
In collaboration with March , Judd made a choice towards atmospheric engines, which were to completely replace turbocharged engines in 1989. Using BV as a base for their new F-1 engine, Judd saved money, while at the same time producing a competitive engine on the road that was in the Ford - Cosworth market, which were the standard choice for teams when the new rules came into effect.
CV
The first engine for Formula 1 from Judd was the CV - a 3.5-liter naturally aspirated V8. He inherited many developments from BV with the only difference - the volume increased to 3.5 liters. March Engineering was the first team to use CV engines. The dominant Williams championships were forced to switch to atmospheric engines, and wanted to choose Judd after breaking the contract with Honda. In addition, Ligier began using CVs in the 1988 season. Judd cars finished four times on the podium during the debut season β Nigel Mansell did this on Williams. The first podium happened at the 1988 UK GP .
In 1988, Judd engines were the most powerful among atmospheric engines, and the cars of Ivan Capelli and Mauricio Guzhelmin often showed high speeds compared to Cosworth DFY and DFZ. At the Japanese Grand Prix March 881, Capelli was in the lead throughout the lap, which the engine with an atmospheric engine could not make since 1983 .
EV
The previous CV model was designed with a 90-degree cylinder block arrangement. Since 1988, the company decided to reduce the angle to 76 degrees in order to make the engine more compact. At first they wanted to make the engine with an angle of 75 degrees, but this was not possible due to computer modeling.
March began using new engines in 1989, as did the Brabham . These teams managed to win on the podium with this engine. The same teams continued using this engine in 1990 , and March was renamed Leyton House Racing. Only this team managed to win the podium that year - second place at the French Grand Prix . In 1991, only Team Lotus remained EV users.
GV
In the "atmospheric" Formula 1, which used engines V8, V10, V12 with a volume of 3.5 liters, the latter showed a higher power. This made Judd replace CV and EV with something new. It was a GV with a 72 degree angle to the cylinders. He began to use BMS Scuderia Italia . Engine power allowed the team to come to the podium at the San Marino Grand Prix .
Brabham and the new team Andrea Moda Formula also decided to use the new engine, seeing its success. However, in 1992, none of the teams that used this engine earned a single point.
Partnership with Yamaha
After leaving Judd from Formula 1, John Judd decided to continue the production of engines and entered into an agreement with Yamaha. Using the GV V10 as a base, Yamaha developed a new cylinder block and called it the OX10 for Tyrrell Racing . Again, Tyrrell failed to score points. An improved version of the OX10B engine improved the speed of the car, and the team achieved a 1994 podium and sixth place in the Constructors' Championship.
Changes in the rules in 1995 forced Yamaha to release another modification - OX10C, the volume of which was already 3 liters, although the engine architecture remained the same. The speed of the car fell compared with last year, and the team managed to earn only 5 points and 8th place in the Cup of designers. In 1996, Tyrrell managed to score as many points with the OX11 engine, which had a new design. In 1997 Tyrrell decided to use Ford engines.
