The Bonneville Salt Flats is a 12,140.5-hectare white salt pan in Tooele County, northwestern Utah.

Since the early 1900s, the area has attracted the brave, the adventurous and, according to Whakatāne’s Llew Gray, the crazy.

They have come with every type of land machine imaginable, from motorcycles to highly customised vehicles with jet engines strapped to the back.

Like so many before them, Gray and Team Kiwi Coupe had a challenge ahead of them when they arrived at the famed United States racing surface with their 1934 Plymouth, ready to try their luck on the salt.

The New Zealanders’ car wasn’t quite finished, so the moment it was out of the box, they got to work.

“The area is totally uninhabitable ... We were there nine days and saw one bird. We definitely suffered from a lack of resources and found ourselves driving around town at night, searching through scrap heaps looking for steel, getting chased out by security guards who wondered why we were there,” Gray said.

“We found a tiny bit of movement in the steering box, but there were no bushes to be found, so we had to improvise, using plastic bungs from plumbers’ pipe so we could make it work. We had a similar issue with the clutch, which we managed to fix with a section of pipe we found on the ground. It was a number-eight-wire mentality. My mechanics did an incredible job,” Gray said.

He and his team spent nine days on the flats, preparing and racing the car through the various stages needed to work their way up the ranks. Each successive stage allowed the team to qualify for the next, with speeds increasing and the risks becoming greater.

“The whole experience was crazy and incredible. It was the most far-out thing you can imagine, even dealing with the heat and glare, with car temperatures reaching 50 degrees Celsius. But our main goal was to just get there and drive, and I can say we did that,” Gray said.

The team worked their way through the licensing process, which increased in 50mph (80km/h) increments, finally managing to acquire a 205-300 mph licence.

The pit crew do minor adjustments to get the car ready for the next speed run.

“Had some issues with the computer on the last run, which was reading the live data but not storing it. We did discover the car was low on fuel pressure. The car was running beautifully, but I couldn’t get it over 6600rpm, and it should have been leaning out to 8000rpm, so we only managed 224.5mph [361.2km/h] and didn’t go as fast as we could have.

“Driving the car meant there was a shitload happening all at once, and it was happening quick. Watching the temperature gauge, rev counter, speedo, track and mile markers with a lot to keep an eye on, you still have time with the pedal pinned to the floor to have those ‘woohoo’ moments.”

The main course is 9.6km long, and there are two of those, followed by a further 6.4km to slow down, totalling 16km, or 10 miles, of racecourse.

The race distance is covered in about a minute and a half. The push car takes around 15 minutes to travel the same distance to collect the car after each pass.

Once inside the car, the driver is strapped down so tightly that movement is very limited. The head is also locked into place, which Gray admits can make him feel very claustrophobic.

The car has no brakes and relies on a parachute to slow down.

“It’s an experience when you pop the parachute; it’s exhilarating. You have to keep your foot on the throttle to make sure the chute comes out square.

“We had a few oil leaks from the valve cover soak into the manifold heat covers, which was smoking the cab out. So, after popping the chute, I’m travelling at 200mph [322km/h] while trying to unstrap myself so I can open the hatch on the roof. I’m just about dying from smoke and fumes and can’t see where I’m going.

“The marshals always knew when it was the Kiwis on course because the car looked like it was on fire as it went past,” Gray said.

Despite meticulous planning, things can always go wrong and often do.

“A couple of cars did roll and come to pieces, and I saw drivers leaving in ambulances. I saw a guy five cars in front of me have his car explode.

“That closed the track for hours as a clean-up crew with magnets had to pick up every metal fragment. These pieces are a danger to other vehicles on course.”

Another aspect of life on the flats that struck Gray was the way everyone supported each other.

“Everyone is there for the same reason and was like one huge family. Teams came over to borrow tools, helped us with parts and even let us use their workshops. The camaraderie was incredible,” he said.

Team Kiwi Coupe walked away with fond memories of their time on the Salt Flats, but they vow to be back next year in the hope of getting the best out of the car.

“The car is 100% mine now and is in storage in a shed about an hour out of Salt Lake City. We are definitely going back for another try next year, as we have unfinished business,” Gray said.

“We loved the whole experience and appreciate that we are now part of a special club. What makes it all even better is that I got to share it with family and friends.”
