Geoff Richardson Engineering the Kimbolton, UK based competition engine building company announces the Richardson 306V. This is a new 60 degree 3.0-litre V6 engine that has been purpose built for the SR-2 class of the FIA Sportscar Championship and is also eligible for the SR-2 class of the Grand-Am sportscar championship that is held in the USA. The SR-2 regulations require engines to be production based and to be fitted with either a single 38.0mm diameter air restrictor or two 27.2mm diameter air restrictors, which effectively limit the power output to around 350bhp. The design of the 306V has been optimised specifically for endurance racing with special emphasis placed fuel efficiency and durability of power. It is based on the all aluminium 24-valve engine used in the V6 Jaguar S-Type road car. In production form the engine generates 240 bhp at 6800rpm and delivers 221 lb ft of torque at 4500rpm. In dynamometer testing without the air inlet restrictor the 306V has developed 400 bhp at 8400rpm and 268 lb ft of torque at 6800rpm.
In keeping with the production power unit the double overhead camshafts are chain driven at the front of the engine but the original variable valve timing system has been removed as this technology is not permitted under SR-2 rules. The 306V weighs approximately 120kg without an airbox and an alternator. It’s bore and stroke dimensions are currently identical to those of the production engine (89mm x 79.5mm), but a 3.4-litre version is under consideration as a future development.
