The Hart 415T is a four-stroke, 1.5-litre, turbocharged, inline four-cylinder racing Internal combustion engine, designed, developed and tuned by Brian Hart of Hart Racing Engines, for use in Formula One racing and competition, between 1981 and 1986. It initially developed about 540 hp (400 kW) in 1981, but power levels later surged, eventually going on to produce about 825 hp (615 kW) in qualifying trim and on maximum boost pressure, in 1985. The engines were used by Toleman, RAM, Spirit, and Haas Lola.[3][4][5]
