Hart Racing Engines

After 1984, major manufacturers like Renault, Honda, BMW, Porsche (funded by TAG), and Ferrari were able to develop their engines to receive much higher turbo boost than the Hart 415T.

The last time it was used was by the Haas Lola team at the 1986 San Marino Grand Prix, with Patrick Tambay qualifying 11th but retiring with engine troubles after just five laps.

At its peak in 1986 when turbo boost was unrestricted, the Hart 415T produced a reported 750 bhp (559 kW; 760 PS) at 11,000 rpm.

The company mainly tuned Cosworth DFR V8s for a number of F1 teams, including Footwork Arrows in 1990 and 1991, Tyrrell in 1990, Larrousse in 1991 and AGS in 1991.

With the introduction of the 3.0 L formula in 1995, Hart switched to a V8 engine named the 830, and these were used by the Arrows team in 1995 and 1996; Gianni Morbidelli took third at the 1995 Australian Grand Prix.

Later that year, Tom Walkinshaw Racing (TWR) bought out Brian Hart Ltd., and merged it into their Arrows Formula One team.
