Wonder no more as the RPE RP-V8 is just that.<br /> <br /> With options of 2.7, 3.0 and 3.2L variants and 400 to 500HP outputs, <a href="https://www.facebook.com/PoweredByRPE">Radical Precision Engineering</a> have the bases covered when it comes to their Suzuki GSX-R Hayabusa based 72° V8 10,500rpm powerplants.<br /> <br /> With an interesting combination of both Formula 1 technology via an engine casting that includes a dry sump system and MotoGP technology via the Suzuki Hayabusa cylinder heads a lot of careful design and production considerations have gone into the engine and James Pinkerton from RPE was kind enough to share some of this with Andre during our recent Goodwood UK trip.<br /> <br /> James and Andre dive into some of the considerations that go into building a 72° V8 as opposed to the easier 90° setup including the reason for this choice, the firing order and how that can create some issues when it comes to engine harmonics. Potential issues from the harmonics are not something that was overlooked with both the small and big pin crank options having the worst of them occur either at points in the rev range generally only used in passing, or above the 10,500rpm limit.<br /> <br /> The pros and cons of the flat-plane crankshafts used are also covered and the reason for replacing stock Suzuki liners with a thicker billet option and why stroker cranks are easier to fit to this engine configuration than a conventional V8. Unsurprisingly these engines have been very successful not just in Radicals own chassis but also in many circuit racing and hillclimb applications.<br /> <br /> The V8 uses as many off the shelf Hayabusa parts as possible in order to keep the maintenance and running costs down for Radical Sportscar racers and owners due to the fact that as good as these cars are to look at, they are 100% produced to be driven as fast as possible and not as sit ornaments. Radical stands behind this fact to the point that they offer a warranty with these engines. No need to explain how unique that is with such a unique track-focused engine.<br /> <br /> Want to learn how to tune EFI?
