The Hyper Racer is a relatively low-cost, high-performance circuit racing open-wheel car for both seasoned and aspiring racing drivers. Manufactured by Racing Cars International P/L, in Melbourne Australia, the Hyper Racer X1 was designed and built by the founders, father-and-son team Jon Crooke (Director of Design) and Dean Crooke (Director of Engineering and Product Development).
5-488: The Hyper Racer's design is unusual for a modern high-performance open wheeler, in that it uses a chrome-moly space frame chassis rather than a Carbon-fiber Monocoque , primarily to reduce manufacturing and repair costs. The suspension features relatively few adjustments, to limit the difficulty of setup for inexperienced drivers. It also uses Ground effects and a relatively large front and rear wing, to increase downforce to increase cornering speeds and improve handling at
10-794: A one-make racing series in Victoria, Australia since 2022. In 2024, the series added interstate rounds and acquired the rights to represent the Australian Drivers' Championship . The Hyper Racer X1 is available in Australia, the US and the UK/Europe. 41xx steel 41xx steel is a family of SAE steel grades , as specified by the Society of Automotive Engineers (SAE). Alloying elements include chromium and molybdenum , and as
15-466: A result these materials are often informally referred to as chromoly steel (common variant stylings include chrome-moly , cro-moly , CrMo , CRMO , CR-MOLY , and similar). They have an excellent strength to weight ratio and are considerably stronger and harder than standard 1020 steel, but are not easily welded , requiring thermal treatment both before and after welding to avoid cold cracking . While these grades of steel do contain chromium, it
20-470: Is not in great enough quantities to provide the corrosion resistance found in stainless steel . Examples of applications for 4130, 4140, and 4145 include structural tubing , bicycle frames , gas bottles for transportation of pressurized gases, firearm parts, clutch and flywheel components, and roll cages . 4150 stands out as being one of the steels accepted for use in M16 rifle and M4 carbine barrels by
25-547: The expense of top speed. The Hyper Racer is powered by a largely unmodified Suzuki Hayabusa motorcycle engine producing 195 hp (144 kW). It uses the Hayabusa gearbox with shifting controlled by a sequential shifter to the right of the driver's wheel, and a Centrifugal clutch , eliminating the need for a clutch pedal. The car uses a Formula 3 tyre, manufactured by Hankook . The Hyper Racer weighs approximately 400 kilograms dry. The Hyper Racer X1 has been used for
