MacDonald, very much a man of the future, and the much-loved Eddie Sachs, Halibrand Ford, perished in the horrific conflagration. Jack didn’t qualify well with a multitude of problems, not least spring/shocks which were way too soft (as specified by car owner John Zinc), and time, pulled as he was by his GP commitments to straddle both sides of the Atlantic.įamously wary at the start of that race – having been warned about how dangerous the Mickey Thompson built Thompson Ford was by Masten Gregory, who didn’t qualify his – Brabham picked up a small fracture in one of those ginormous aluminium fuel tanks in the horrific lap two accident caused by Dave MacDonald losing control of his Thompson Ford in the middle of the field. About 59 gallons of fuel when full (MotorSport) Indy 1964 (MotorSport) Note too the main tanks offset to keep the bulk to the inside. Note the bungee’d in place oil tank and top-of-chassis little fuel tank. Long-stroke, 4128cc, 420bhp 6600rpm Offy sits tall in the frame, Colotti-Francis GSD transaxle and inverted lower wishbone, single top link, two radius rods and coil spring/shocks, rear discs, knock on hubs and beefy driveshafts all clear (MotorSport) Spaceframe chassis, upper and lower wishbone/coil spring-shock and roll bar suspension.
BT12-1 in build at Motor Racing Developments, Weybridge, Surrey circa April 1964. The pacey package also featured a robust Colotti Francis T37 transaxle. They were stunned by the speed of the itty-bitty, mid-engined roller-skate despite giving away 1.5-litres to the bulky Offy engined roadsters – which hung onto The Milk until 1965 of course.īrabham returned in 1964 with Ron Tauranac’s BT11 derived, spaceframe BT12 powered this time by an injected 4.2-litre Offenhauser twin-cam, two-valve four. Their Cooper T54 Climax FPF 2.7 blew the minds of the establishment.
Jack Brabham put the cat amongst the Indy pigeons in 1961 together with John Cooper.
