The Hayabusa V8 engine we like so much here at The Kneeslider, powered a Radical SR8 to a new lap record for production cars at the Nurburgring. The former record holder, a Porsche 996 GT2 was eclipsed by 20 seconds! Records like this normally get lowered by a second here and there, the Radical SR8 just demolished it. For those of you who wonder why I spend so much time talking about motorcycle powered cars and their variants, this should give you an idea. They're fast! Really fast! Remember, too, these guys have a larger displacement version of this engine now going into their new SR9. Neat.
