Complete Replacement For R22 Factory Exhaust System
Power Flow Systems is in the final stages of STC approval to
bolt-on their industry leading 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 PFS 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, at a
fraction of the cost. With the new exhaust system, owners then can
operate their helicopters using the Beta II engine performance
limitations.
Flight tests have confirmed that the improved 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. Pilots flying at original cruise settings will
see the fuel burn reduced by up to 15 percent. Unlike the original
exhaust units, a Power Flow Tuned Exhaust System does not require
mandatory replacement at 2200 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 6 - 8 hours and features a replacement manifold
pressure gage, 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.
