Suzuki GSX-R Hayabusa based 72° V8, 105kg, 500HP, 10,500RPM weapon. • This is just one topic taken from a longer interview found here: • 105kg, 500HP, 10,500RPM ‘Hayabusa’ V8... • 0:00 - Why not a 90° V8? • 0:15 - 72° For Packaging • 0:28 - Tradeoffs • 0:55 - 90° vs Oddfire 72° Simplification • 1:12 - Harmonics • James from Radical Performance Engines 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. • Want to learn how to tune EFI?
