Another one I've had a hand in building (I shaped most of the wooden bucks for this motor & had no fingerprints for about 3 months, lots o filler work!) Arrows V10 engine & box with custom profile Kent Cams, carbon/ honeycomb chassis tub & a total weight of just 440kgs Only 15,000rpm now to make it more tractable on the hills. http://www.youtube.com/watch?v=WNgYh9vBc84
