Weekly Motor Fix: 1931 Bentley 4.5L

25 February, 2015

 

Despite my knowledge being a bit rusty when it comes to cars that are nearly 100 years old, I’ve always been a fan of old race cars. Previously I’d been scared to the point of tears at the thought of being inside one of the modern-day race cars, which was an oddity considering I was always surrounded by them and adored them, yet the thought of being inside one seemed like imminent death. With safety regulations and changes over the years, I really didn’t have a lot to worry about. Roll cages are now standard practice and the quality of safety never ceases to grow and expand.

However the race cars that I wasn’t scared of were the classics. They reminded me of Chitty Chitty Bang Bang and the thought of flying around the world. When I popped down to Caffeine and Classics on the weekend, I expected a quiet Sunday morning wander before lunch, but what I ended up seeing was quite beyond that. Seeing many Mustangs and little Minis, I had a good idea of what the majority of cars in attendance would be. I met up with a few friends and had a wander around the show, spotting a few oddities, and spotting a big green thing at the back by itself. Getting closer, a friend of mine said, “Check out the Bugatti over there!” The closer we got, the closer we realized the ‘B’ was for Bentley, not for Bugatti.

The front-mounted supercharger stood out like a sore thumb behind the headlights and horns. Working our way back through the engine, the bonnet strops, and into the cabin, it’s a remarkable sight, and a piece of engineering carefully restored and maintained to ensure it’s keep at such a high standard. It had grabbed my attention so strongly that I had to have a quick Google, which allowed me to figure out what I was looking at — a Bentley 4.5L Blower. Having once raced at Le Mans on an unsuccessful journey, the Bentley 4.5L Blower was renowned as being one of the first race cars to ever install a supercharger and, although not successful, it managed to create a stir in the circuit.

Driving one of these pre-World War II cars comes with a little more footwork than a modern car. With the accelerator situated in the middle of the floor and the brake off to the right, you’ve got to think a little harder than usual to ensure you’re not speeding up instead of slowing down. Then there’s the engine. What came as a surprise to me is that the 4.5(4)L engine is a single overhead cam straight-four, much like that of say a Honda D13B. Unlike a Honda however, there’s said to be around 40 Blowers left in original condition around the world with the market changing and the cars ageing. The owner was leaving as I was arriving however; strapping on his helmet and goggles, the man was all prepared for the journey ahead. It’s definitely not as easy as being in a modern-day car, but pedalling the Bentley beast around would certainly be an amazing piece of work to be associated with.

 

Lunch with… Jim Palmer

In the 1960s, Hamilton’s Jim Palmer won the prestigious ‘Gold Star’ four times and was the first resident New Zealander home in the New Zealand Grand Prix on five consecutive occasions. He shared the podium with Stirling Moss, Jack Brabham, Bruce McLaren, Graham Hill, Jim Clark, Denny Hulme, Jackie Stewart, and Chris Amon. The extent of his domination of the open-wheeler scene in New Zealand will probably never be matched or exceeded. Yet he’s always been modest about his achievements.

Who would have thought it would become such a worldwide motorsport star when Ford introduced the humble Escort in 1967?
Its popularity, particularly in Mark 1 form, is now of iconic status. Our cover story for this issue is on a 1968 Ford Escort Mark 1, Alan Mann Racing Tribute. We talked with the owner of this very special Escort, finished in tribute also to the owner’s father.
“Most children love speed, and motorsport typically comes courtesy of a parent, and Elliott is no different. His engineer father, Mark, had a love for motorcycles and going fast; however, when children came along, he swapped two wheels for four, in the form of two Ford Escorts.
Little did Mark know it at the time, but the humble Escort was about to weave its way into the family fabric once and for all.
After emigrating from London to New Zealand, Elliott recalled one evening when he was 14 being invited to tag along by his father, helping a friend convert an Escort road car into a racing car. This was the pivotal moment when Elliott remembers the motorsport bug taking over. He knew he had to have his own one.”
