Think your rotary engine has a dope engine idle? This RX-4 or Mazda Luce isn't your typical 13B powered coupe. This RX-4 is powered by not four, but six rotors. New Zealand tuning firm Pulse Performance Race Engineering has built this rotary monster, which is good for 813 horsepower. Spectators at the 2013 V 4 and Rotary North Island Jamboree were treated to a test run held at Manfeild Park race track. The RX-4 was loud enough to distort any onboard footage. Don't just listen to me, check it out for yourself! Brap brap brap!
