RP-V8 Series

RPE RP-V8 (see Powertec RPA) is the name of a V8 engine series developed by RPE. The design is loosely based on the 1.3 litres (79.3 cu in) inline-four engine produced by Suzuki for their Hayabusa motorcycle. The company have designed their own cylinder block and use existing Suzuki cylinder heads. The two cylinder banks are inclined at a 72-degree angle. The engine is mated to a purpose-built transaxle designed by Quaife. There are currently two versions of the engine available, which have been updated for 2011. First is the base 2.7 litres (164.8 cu in) model which retains the original bore and stroke of the K8 Hayabusa design and produces 430 horsepower (321 kW; 436 PS). Second is the bored and stroked 3.2 litres (195.3 cu in) model which produces up to 500 horsepower (373 kW; 507 PS).
