The Hurricane is a true race bred naturally aspirated manifold; old school attitude with new school engineering. The Harrop Hurricane ITB manifold has long, straight runners with a smooth transition to the inlet port to increase flow efficiency. The Hurricane is the only ITB manifold for LS series engines to feature complete fly by wire throttle integration. This manifold has also undergone rigorous testing with over 11,680 simulated racing kms completed around one of the toughest tracks in the world, Mt. Panorama in Bathurst, Australia.
