Walter Boyd, founder of MacroAir Technologies and Walt Boyd Racing, is an innovator by nature.

Having held various jobs within the engineering field and owning many different companies, Boyd has been able to cultivate his innovative nature to develop a wide range of products, many of which are still in use today.

While studying mechanical engineering at both the University of Connecticut and University of Bridgeport (1954-1962), Boyd worked various jobs – including as a commercial deep-sea diver specializing in underwater welding, drove racecars, and started his first of many companies, Motorsport Design Corp., designing and building racing equipment.

After moving to California in 1969, Boyd worked in various capacities for Formula One, Indycar, and Can-Am race teams.

In 1973, Boyd started Boyd and Stellings Company building a highly successful line of racing motorcycles and components. After selling the company in 1976, he served as chief engineer for Chinook Motor Homes, where he designed a new RV concept that was recognized with many industry awards.

His third company, Mechanization Systems Co. (MSC), developed equipment to mechanize roofing operations in the U.S. and Europe; the company’s concepts are still the standard used in the U.S. today. In 1982, Boyd sold the roofing related products, but continued to operate Mechanization Systems Co. with his son Eddie. The team specialized in designing, fabricating, and manufacturing a wide variety of products including racecar equipment, engine components (for Nissan’s GTP racecar), pick-up truck accessories, agricultural equipment, crane accessories, an engine dynamometer for the manufacturer of the Predator drones, large truck-mounted video screens, etc.

In 1998, MSC was hired by the Cooperative Extension of the University of California, an arm of the university that worked to promote and aide California agriculture, to make some parts for an experimental 20-foot diameter wooden paddle fan sought to cool dairy cattle to improve milk production. The project was not successful: the fan didn’t move much air, was inefficient, and would have been prohibitively expensive to manufacture or transport in any quantity. But, the theoretical efficiencies of a large, slow moving fan set Boyd to thinking about the possibilities for human comfort as well as animals, which would require a fan that was efficient, quiet and safe. It would also require a fan that could be manufactured in quantity, was economically shippable, and could be installed inside buildings

From his racecar involvement, Boyd had considerable knowledge of low-speed aerodynamics, which he knew would be the key to creating such a fan. He also drew upon his experience with the aluminum extrusion process, which he saw as an economical way to produce an airfoil blade of the proportions required.

With his son Eddie essentially running the company, Boyd spent the next 10 years dedicated to the development of HVLS (High Volume Low Speed) technology i.e., an understanding of not only factors that affect the fan’s performance, but also how the air from such a fan actually behaves, and how that air movement can be manipulated to optimize human comfort. It was on the basis of that knowledge that MacroAir Technologies Inc. was formed.

Although officially retired from MacroAir, Boyd’s innovative nature hasn’t taken him far from the company, now run by his son and employing his grandchildren in key roles as well. He is still involved with new product and technology development and, in his spare time, enjoys his five (another on the way) great-grandchildren and passion for racecars.


NAME-Kyle Cline

AGE-  32

OCCUPATION- CNC programmer


CLASSES COMPETED IN- ASA 4s, Nascar Super Late, Dwarf Cars, Lightning Sprints, Midgets, Sprint Cars, Late Models, Modifieds


Kyle has won in almost every division he has raced. During his time racing he has won 3 championships, over 30 main event wins, and set 3 track records. Kyle was awarded for the most wins in a single season alone, with some big wins in the Dwarf Car, such as the turkey classic in Victorville, CA twice, and the cotton classic in Hanford, CA.

Walt Boyd Racing was formed in 2008 with the joining of Walt Boyd and Kyle Cline. Walt Boyd Racing showed their presence right off the bat, by winning three main events in their first year together, in the CDCRA Dwarf Car series. One of those wins was the turkey classic in Victorville, CA. The team went on to win 23 races, and received the CDCRA award for the most wins in a single season in 2009.

Walt Boyd Racing went on to win 3 championships, and over 20 main event wins in the next 8 years alone. They also set 2 track records running in many different classes, from Dwarf Cars on dirt and pavement, USAC and URS midgets, USAC sprint cars, Nascar late models, and Lucas oil modifieds.

Walter Boyd

Owner of ​​Walt Boyd Racing



Kyle Cline has learned many things from Walt Boyd since he and the innovative racer and engineer teamed up seven years ago. The most important thing is one of the most easily attainable, though.

"We made an agreement that as long as we have fun we'll keep doing it," Cline said. "I've come a long way as far as learning what racing is all about and I've got Walt to thank for that. When I first got in to racing I was going to be the next Kyle Busch. I didn't have fun until I started racing for Walt.

"Win or lose we have fun at every race we go to."

The races Cline and Boyd will be going to this year are the 10 on the schedule for the Lucas Oil Modified Series presented by LoanMart.

Cline, a 32-year-old who lives in Apple Valley, California, started racing in 2001 in the Mini Cup or MiniStockar class at Orange Show Speedway in San Bernardino, California, with his father, Roy, as his crew chief. The next year, they moved up to Pro 4, at the time one of the most popular and competitive stock car classes, and also raced a Super Late Model until 2007, when he and Boyd met and began their association.

The first step was Dwarf Cars, the 5/8–scale cars with 1928 to 1948 roadster bodies that were the forerunners of the Legends Cars so popular today. Cline said they "went on a traveling spree for a couple of years" and won 28 of 32 races in that span. He also won all seven races at Orange Show Speedway in 2010 and a couple of pavement titles in 2010 and 2011, then moved into open wheel racing in the Ford Focus Midget and USAC Western States Midgets series and tried his hand at dirt track racing.

Midway through last season, however, they were ready for a change. Cline said he loves driving on dirt and learned a lot at it, and for a while they were looking at running a dirt Modified. Then a friend suggested that they go to the Lucas Oil Modifieds race at Irwindale Events Center last August to get a feel for that series.

Cline and Boyd were impressed enough to make an unsuccessful offer for Larry Gerchman's car. Instead, they bought a car from Idaho driver Tom Hill and were familiar enough with it to finish sixth in the next race in the series, at Blythe, California, in September, but were sidelined early the next time out – at Lake Havasu City, Arizona, in October – and weren't able to make a qualifying attempt at the November finale in Las Vegas.

"I love it," Cline said of the series. "I like the way we're treated. They make everybody feel at home. We've stripped the car apart and pretty much rebuilt it and I'm excited about the series next season.

"Win or lose, we're going to have fun at every race we go to."
