Power Flow Systems, Inc. is in the final stages of STC approval to bolt-on its high performance exhaust system to a Lycoming O-320 powered-Robinson R22. This product, Power Flow’s first on a rotorcraft, was designed in cooperation with Performance Aviation in New Zealand, where it has already received CAA approval.
The Power Flow Systems’ kit will be a complete replacement of the R22 factory exhaust system from the cylinders on down. It is like upgrading the R22 HP Alpha or Beta to a Beta II, according to company officials, who note that with the new exhaust system, owners can operate their helicopters using the Beta II engine performance limitations.
Flight tests have confirmed that the system results in an additional eight knots cruise speed at the same manifold settings. The R22 will also develop a 200 to 300 foot per minute increase in climb, company officials said, adding pilots flying at original cruise settings will see the fuel burn reduced by up to 15%. Unlike the original exhaust units, a Power Flow Tuned Exhaust System does not require mandatory replacement at 2,200 hours.
Power Flow’s “Beta II in a box” comes with a 60-day money back guarantee and a one-year/500 hour warranty. The system can be installed in six to eight hours and features a replacement manifold pressure guage, as well as a new carburetor heat box and cabin heating system that utilizes the R22’s existing connections and ducting.
Power Flow, which already has 3,700 tuned exhaust systems on certified fixed wing aircraft, is now taking orders for the 0-320 powered Robinson R22 Helicopter. Once approved by the FAA, the completed orders will be shipped on a first come, first served basis.
