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.

 

A tradesman’s estate — the Cortina GT Estate

The owner of our featured car, Rod Peat, used to rally a Cortina GT back when the words ‘rally’ and ‘trial’ were interchangeable. In times after that he could also be seen beside Mal Clark in various Targa NZ rallies, getting the famous Rover V8 or Lotus Cortina in spirited fashion around and over the various special stages that make up those events. After children, houses, and career, Rod decided it was time to own a GT again.
A search on the various systems available turned up a car Rod and probably most of us didn’t even know existed: a genuine Ford factory Cortina Estate GT.

For the love of cars

Passion, Pride & Joy:
A new chapter for New Zealand’s classic car custodians
In the world of classic and collector cars, continuity matters. Not just of ownership or
provenance, but of care shaped by skilled hands, patience, and deep respect for the machines themselves.
Since 1973, Auto Restorations has existed for this purpose: to ensure these cars live
on, not as relics, but as working expressions of design and engineering. Over more than five decades, we have restored and returned countless vehicles to the road and racetrack, and in recent years expanded our service offering to keep them
performing at their best.
Today, we are proud to introduce the next step in that journey: This is not a reinvention, but a natural evolution. A name that reflects the full scope of what we now offer, while staying true to the standards and values that have always defined us.
