Half a century of racing

Since the 1960s, NAR Group has been the go-to supplier for car cooling products, consistently meeting the needs of club racing teams. Over the years, NAR Group has equipped numerous racing teams with cooling solutions, ensuring peak performance on the track. From vintage classics to modern-day marvels.

Some examples span back to our oldest customers, Pearsons Engineering who we have assisted in supplying the cooling products for their historic Jaguars on various race days throughout the decades

We have also helped develop cooling for British racing manufacturers such as Van Diemen for the Silverstone international circuit during the Formula Ford tournament in 2007

In the 70s we worked closely with the locally based F1 team shadow racing. We manufactured the radiators from 1973 onwards. The team debuted in Formula One at the 1973 South African Grand Prix with the Shadow DN1 chassis. Two cars were available for drivers Oliver and Follmer, as well as one car for the privateer team Embassy Hill of Graham Hill who ran his team alongside the Shadow works team.

The Aston Martin Bulldog, styled by William Towns, is a British, one-off concept vehicle produced by Aston Martin in 1979. NAR assisted in the early cooling designs to help showcase Aston Martins engineering ability.

On 6th June 2023 BBC Radio 4’s news reported that the car had reached its promised 200 MPH speed at Campbeltown Airport in Scotland, reaching a speed of 205.4 mph (330.55 km/h)

Aston Martin Continuation Series 2017-2019

In 2017, almost 60 years on from when the original cars were made, the DB4 G.T. Continuation was hand-built on the very same site in Newport Pagnell as its illustrious forebears. It marked the return of production to the historic home of Aston Martin for the first time since the last V12 Vanquish S was completed in 2007 to secure the status of the world’s oldest purpose-built car manufacturing facility.

NAR were asked to manufacture radiators, header tanks and oil coolers using the same material and build methodology as was employed in 1959

Capturing the spell-binding essence of Aston Martin’s illustrious heritage, the Continuation series has since seen the production of DB4 GT Zagato Continuation in 2019 and the Goldfinger DB5 Contination – complete with Bond-inspired – gadgets in 2020.

NAR manufactured radiators and oil coolers for Swift Engineering which covered a wide array of racing cars from this era for the Nippon Championship, It is considered to be the pinnacle of single-seater racing in Japan or Asia as a whole, making it one of the top motorsport series in the region.

NAR worked closely with racing teams Red Bull (RB3 Renault RS27) and Williams ( FW29 Toyota RVX-07) supplying the cooling products for their race cars during the 61st and 62nd season

NAR also worked with various race teams such as: Richard Childress Racing/Joe Gibbs Racing/Roush (RFK) /Robbie Gordon during the Nextel and Sprint Cup series

Driver Elliott Sadler (Childress Racing) moved over from KHI in 2012, winning four races.

NASCAR stock cars encounter significant challenges with their cooling systems during races due to the intense heat generated by the high-performance engines. The close-quarter racing exacerbates the issue, as cars often run bumper to bumper, restricting airflow to the radiators. Additionally, the aerodynamic designs aimed at enhancing speed can inadvertently impede cooling efficiency by disrupting the airflow to crucial components. Engineers tackle these issues by meticulously designing ducting systems to optimize airflow, implementing larger radiators, and utilising innovative materials to enhance heat dissipation without compromising speed or aerodynamics.

NAR faced the challenge head-on, leveraging our expertise in British F1 engineering. We devised an innovative solution in the form of an aerodynamically efficient fin, known as the CD-Fin. This design featured a 30-degree exit angle for both inlet and exit air, significantly enhancing airflow efficiency along the NASCAR racing line. Addressing a prevalent issue of overheating during races, our solution effectively optimized cooling performance within the demanding NASCAR environment.

INDYCARs confront notable hurdles with their cooling systems during races, primarily stemming from the intense heat generated by their high-performance engines. The aerodynamic design, aimed at maximizing speed, often complicates cooling efforts by limiting airflow to critical components such as radiators and intercoolers.

NAR GROUP was invited to conduct research and development for the racing series, specifically tasked with enhancing cooling systems for the prominent race teams like Genassi and Andretti, focusing on their third-generation racing cars(IR-03/IR-04/IR-05).

Vehicles participating in the Le Mans racing face complex cooling challenges inherent to endurance racing and high-performance engines. The prolonged duration of racing sessions places immense strain on cooling systems, as engines operate at peak performance for extended periods, generating substantial heat. Moreover, the aerodynamic designs optimized for speed often compromise airflow to critical cooling components such as radiators and intercoolers. Additionally, the diverse racing conditions encountered during the 24-hour endurance event, ranging from intense heat to nighttime chill, necessitate versatile cooling solutions capable of adapting to varying environmental factors.
