On November 12th, Power Flow Systems announced the debut of its
all-new tuned exhaust system for the Beech Bonanza. Though
PFS now has systems on over 3,500 aircraft, the Bonanza will be the
company’s first tuned exhaust for a six-cylinder
The new system required a “clean-sheet” design to
fit inside the cowling while still providing the necessary length
for increased performance. The high performance tuned exhaust will
feature Power Flow’s patented components including mandrel
bent tubing, cabin heat design, and headers comprised of their own
independent slip joints eliminating the need for clamps.
Power Flow systems significantly increase engine efficiency and
horsepower by improving exhaust fume evacuation from cylinders;
with fuel flow improved, engines are able to run cooler, smoother,
and burn less fuel at the same airspeeds as non-modified
Initial testing shows an increase in cruise speed by up to seven
knots for Bonanza aircraft, resulting in a fuel savings of up to
1.5 gallons per hour. In addition, the tuned exhaust system
shows up to a 15 percent increase in the rate of climb, as well as
a service ceiling increase by 2,000 to 5,000 feet.
The company intends on seeking supplemental type certification
for the Bonanza’s IO-470, IO-520, and IO-550 engine
configurations. PFS is currently taking deposits from Bonanza
owners as part of their Pre-Production Pricing Program, which will
save customers up to $1245 off the retail price depending on the
number of deposits received.
For those wishing to save more while doing something charitable
during the Holiday season, Power Flow Systems has joined up with
the U.S. Marines’ Toys for Tots Foundation. For every
$50.00 donated to Toys for Tots by a customer, Power Flow Systems
will triple the donation amount in the form of an instant rebate on
any new tuned exhaust system.
