It is capable of 0–60 in 2.7 seconds, 178 miles per hour, and a 2.5 g's of lateral acceleration. This record was beaten by the 991 generation Porsche 911 GT2 in September 2017 with a time of 6:47.25. In August 2009 Michael Vergers, driving an SR8LM, set the new lap record (6 minutes, 48 seconds) for a road legal production car at the Nürburgring Nordschleife circuit. A further variant, known as the SR8LM, increased the engine to 2800 cc and brought power output to 455 hp (339 kW). The SR8 also features one of the largest engines Radical has ever put in their cars, with the 2700 cc RPE RPX V8 constructed by combining elements of Suzuki inline-4s, and producing 430 horsepower (321 kW). It is capable of 2.3 g of lateral acceleration.īased on the SR3, the SR8 is a more extreme version intended for track use but can be registered for the road. It is powered by an advanced 182 horsepower RPE-Suzuki four-cylinder engine capable of propelling the car 0–60 in 3.5 seconds and eventually to a speed of 138 miles per hour.
#Quaife sequential price series#
The SR1 is the first Radical to have its own racing series – The SR1 Cup – a club, owner-driven racing series that combines competition with training.Ĭombining exceptional performance and handling with LMP styling and low cost of ownership, the SR1 is priced at £44,500 + VAT. The Radical model range has seven different models in various options, most notably in the powerplants, are available on all of the cars. Official partner Rollcentre Racing would debut the car with success in the Le Mans Series and 24 Hours of Le Mans, and SR9s in the hands of independent teams would contest the 24 Hours of Le Mans a further four times. In 2006, Radical would make its largest leap into international motorsport with the development of the SR9, a complete Le Mans Prototype in the LMP2 class. An enclosed gear drive unit was developed specifically for the car to replace the traditional motorcycle engine chain drive. The car uses a Suzuki-based engine tuned by Powertec (now RPE) which offered 1300 cc or 1500 cc versions and a maximum of 260 hp (190 kW) in the latter. Launched in 2001, Radical's next creation was the two-seater SR3, a car which could compete in international racing, such as the FIA's C3 class. The cars were also brought to the United States for the first time, for use in the SCCA D-Sport class in 2000. Available with Kawasaki or Suzuki engine up to 1500 cc in displacement, the Prosports were even more powerful and faster than the Clubsports, and included F3-size slick tyres and an adjustable rear wing. The same year, Radical debuted their second model, the Prosport. Backed by the British Racing and Sports Car Club, the series featured identical cars that were open to anyone who owned an 1100 Clubsport. In 1999, Radical had built enough 1100 Clubsports that they decided to create a one-make series based around the car. The cars were intended to run in the 750 Motor Club's races under the Sports 2000 category, with founders Abbott and Hyde driving. The company's first car, built by Phil Abbott in 1996, the Radical 1100 Clubsport, was based on a Kawasaki motorcycle engine placed inside a small open-cockpit chassis. *Version 2 Update* We are now supplying the QKE8J Version 2 which has been updated with a revised shift mechanism which incorporates the ability to connect a pneumatic shift system directly to the gearbox from factory.Rollcentre Racing's Radical SR9 at the 2006 24 Hours of Le Mans.
