Here is a cool “little” car.  It’s basically an oversized Go-Kart powered by a Yamaha R6 engine.  The car is claimed to have done a 1:14 lap time on the Streets of Willow Road Course.  The cost of a rolling chassis is around $12,500, and R6 engines can be found for around $1000 to $3000 dollars. Not a bad performance to dollar ratio at all!
