William Medcalf to race 1936 Bentley Pacey-Hassan at Members’ Meeting

9 March 2018

William Medcalf, owner and founder of the eponymous William Medcalf Vintage Bentley is set to race the fearsome Pacey-Hassan Bentley at this year’s Goodwood Members’ Meeting, on behalf of owner Andreas Pohl, as it competes in the Bolster Cup race.

Medcalf is used to racing monstrous vintage Bentleys from the 1920s and 1930s, having competed in events around the world from Goodwood to Le Mans, but this will be the first time he has raced a Bentley at the Members’ Meeting.

Despite the car’s motorsport pedigree, the fearsome ‘Pacey’ has never raced at Goodwood. Spectators at the 76th Members’ Meeting will be the first to witness the car racing at Goodwood since it was built 82 years ago, as William tussles with some of the fastest pre-war cars ever created.

Wally Hassan was one of the greatest Bentley mechanics of his generation; after the company was sold in 1932, Hassan was retained to work directly for Woolf Bernato on his personal cars. Barnato decided to build an 8 litre Bentley Brooklands outer circuit single seater (later to be known as the Barnato-Hassan). The purpose was to take the outright record at Brooklands. Bill Pacey approached Barnato and asked if his ‘mechanic’ could build him a 4 ½ litre version at the weekends.

As a result, the Pacey-Hassan was born, but with one unique design feature only later admitted by Hassan. When he built the engine, he fitted several compression plates to the block. For the 1936 season when the car was successful, fresh handicaps were applied which were known to be quite harsh.

Hassan would pull the engine down to make sure everything was at its best, and when he reassembled he would forget to fit all of the compression plates! The handicappers were astonished that the car remained so competitive for so long.

The practice of pulling the engine down and checking it had proved fruitful. Eventually when all the compression plates were exhausted, the car was no longer competitive in that form. Hassan then moved on to supercharging the engine for the 1937 season. The Pacey-Hassan achieved an ultimate lap of 129.03.

It is now looked after by the team at William Medcalf Vintage Bentley. Using its extensive expertise, the Pacey is now reported to produce over 230bhp.

“To race a car as special as this for the first time on a circuit as evocative and historical as Goodwood is an immense privilege and also a challenge. Looking after the car for its owner is a pleasure, to race it on his behalf is a true honour,” said William Medcalf.

“The Pacey-Hassan is a brute with lots of torque. There is an impressive line-up of the best pre-war cars and some of the best drivers of today so I will have to be giving it the beans. Goodwood is a tricky circuit and finding grip in the wet for this car could be an issue. I’m sure we can please the spectators with some close racing and maybe the odd bit of oversteer!”
