Power Flow Systems, which has tuned exhaust systems on more than 3,500 aircraft, has designed a tuned exhaust system for the Beech Bonanza. The company plans on obtaining STCs for the IO-470, IO-520 and IO-550 configurations.

Initial flight tests revealed that Bonanza owners can expect an increase in cruise speed by up to seven knots (four knots are guaranteed), company officials said. When flying at established cruise speeds, owners can expect a fuel savings of up to 1.5 gallons per hour. Rate of climb improves by up to 15% and the service ceiling will increase by 2,000 to 5,000 feet, officials add.

Power Flow tuned exhaust systems increase engine efficiency and horsepower by doing a better job of evacuating exhaust fumes from cylinders, allowing better fuel flow into the chambers, Power Flow officials explained, noting engines run smoother, cooler and burn less fuel at the same airspeeds as a result.

Though the company has been tuning exhausts on four-clyinder engines for 10 years, the Bonanza is Power Flow’s first venture with a six-cylinder engine. The company is now taking deposits from Bonanza owners as part of it Pre-Production Pricing Program, which saves deposit holders $715 to $1,245 (depending on the total number of deposits received) off the retail price of $6,500.
