The RPE RP-V8 engine is a very high-power, lightweight V8 racing engine. The RP has been continuously developed since 2004 and is fully race-proven, with over 160 units manufactured to date. Amongst many successes, the RP unit has been used by Radical Sportscars to smash the Nürburgring Nordschleife Production Car Lap Record, first in 2005 and again in 2009.
The RP-V8 Macroblock engine comprises Suzuki GSX-R Hayabusa cylinder heads, mounted to a dedicated dry-sump crankcase. A flat-plane steel billet crankshaft transmits power to the gearbox, while a gear drive rotates the Formula One-specification scavenge pumps, twin oil supply pumps and the coolant pump.
The RP range of engines are available in various capacities from 2.6 to 3.2 litres. The 2011 specification RPX 2.7 litre and RPC 3.2 litre variants incorporate all-new 2011 Suzuki GSX-R 1340cc cylinder head technology, while the 2.7 also includes brand-new RPE developed tuned inlets.
