Title: Brian Hart Ltd
Post by: Tony on September 04, 2006, 15:48:14 PM

Hart was trained in airframe and aero-engine design by Britain's De Havilland aircraft company.
Before working as an engineer at Cosworth in its early years. He also enjoyed a very successful racing career in Formula Junior & F3 in 1958 + 1963. Hart scored numerous wins in Formula Junior and sports car events with Lotus and Terrier chassis, taking third place in the Grovewood Awards for 1963.
Moving up to Formula 2 Brian gained an almost immediate victory in the Pergusa GP, driving a Ron Harris entered Lotus and although he stepped back into Formula 3 in 1966 he was to become an F2 regular. In 1967 the world also saw the only appearance on the Grand Prix scene of the awkward Protos F2 machine. Its drivers were Kurt Ahrens Junior and Brian Hart!

Mostly he raced for Bob Gerard for whom he won the 1969 Rhine Cup race at Hockenheim after a great drive.

He started an engine building business, Hart inevitably found less time to go racing and he eventually retired at the end of 1971 as an F2 driver with Ron Harris's Lotus factory team. In the early 1960s he even raced in a few non championship F1 races!

In 1969 he established Brian Hart Ltd.

The idea was to service Ford's FVA racing engines.
He was soon commissioned to develop Ford products and designed the Ford BDA, which would become the backbone of Ford's rally programs throughout the 1970s.

In 1971 Ronnie Peterson won the European F2 title using a Hart FVA and the following year Mike Hailwood won the title with a BDA.

The arrival of BMW and Renault in F2 plus Ford's unwillingness to increase its involvement prompted Hart to design his own F2 engine. He produced the Hart 420R, it first raced in 1976 in a Chevron sportscar. This went on to become an effective F2 engine, winning races in 1977 and 1978.

The winter of 1978-79 proved to be a turning point for Hart, when the Toleman F2 team decided to finance his R&D programs. The result was that Toleman-Hart dominated the European F2 Championship in 1980 with Brian Henton and Derek Warwick achieving a 1-2 finish in the championship. Toleman then commissioned a 1.5-liter turbocharged version of the 420R for F1 and the team entered GP racing in 1981.

Towards the end of 1982 the Toleman-Hart combination began to show its potential and by 1984 the team was good enough to attract Ayrton Senna. In his first F1 season Ayrton finished second at Monaco and third at Brands Hatch and Estoril.

For the next three years Hart supplied a variety of F1 teams, notably Carl Haas's FORCE Lola operation but at the end of 1987 the F1 rules changed to 3.5-liter normally aspirated engines. Hart did not have the money to build his own engine and so he joined forces with Cosworth to develop the company's DFZ and DFR engines, notably with Tyrrell. This work continued into 1990 when Jean Alesi produced some stunning performances.

By 1992 Hart had funded the design of his own V10 engine, the Type 1035 and in November that year he announced an exclusive deal to supply the Jordan Grand Prix team in 1993 and 1994. The result was highly competitive but at the end of 1994 the team was given the chance to use free Peugeot V10 engines and Hart had to do a deal with Arrows instead, which was struggling for money. The team used Brian's V8 engines because there was no money to build the new V10 that Hart was planning. In 1998 Hart moved on to Minardi but in the summer he began to work on another V10 design. This became the Arrows V10 in 1999 when Tom Walkinshaw bought Brian Hart Ltd. There was legal action over money in the course of the 1999 season and Hart disappeared from the F1 scene.

It was Brian Harts development engine he built for racing that are the bare bones of the Cosworth BOA and BOB engines.
Cosworth bought the rights to the 24v version he designed based on the old 12v Colonge engine block.
It was re-designed by Cosworth to suit what Ford wanted for the Granada.

Above there is loads of references to various race engines but Hart also worked for ford on many projects such as the GAA race engine and the colonge engine below that some may find familiar!
