The Tornado Alley Turbo Whirlwind III™ Bonanza

The Tornado Alley Turbo Whirlwind III™ Bonanza is the finest turbonormalizing package available for your TCM IO-520 or IO-550 Powered Bonanza today. Utilizing State-of-the-art Engineering and the finest components attainable, the turbonormalized Whirlwind III™ Bonanza not only provides sea-level power up to 20,000 feet but also significantly improves low altitude (less than 12000') speeds as well. With the "magic" of turboGAMIjectors® fuel injectors, the Whirlwind III™ bonanza will fly faster; and faster on less fuel, with cooler engine temperatures than normally-aspirated Bonanzas.
Recent improvements including the Rammer II with Scoop Duct™ and other changes have compelled us to designate our new production configuration as Whirlwind III™.
