Power Flow Systems, Inc. was founded in
1997 by Robin Thomas. Mr. Thomas is also the president of
Laminar Flow Systems, Inc. which developed and manufactures
speed modifications for Piper PA 28, 32 & 34 aircraft.
Power Flow's first FAA STC approval was
in March of 1999 on the C172 with the Lycoming O-320 engine.
This approval was for the very distinctive 'external' tailpipe
design. With this design, dynamometer data showed that this
allowed the engine to produce 23.75 more horsepower than the
factory equipped exhaust! Additional benefits include more
torque, shorter takeoff distance, higher rates of climb and
faster cruise speeds or a fuel savings at current speeds.
Power Flow has expanded to other popular
Lycoming O-320 and O-360 aircraft. This includes fixed gear
C177, the Grumman AA5 series, Piper PA28's, Mooney 4 cylinders,
Beechcraft 19/23 series and Glastar/Sportsman experimental
aircraft. Power Flow exhaust systems are made of all stainless
steel components and feature slip joints for improved durability.
The exhaust system is designed to require no modifications
to the engine, though some aircraft models may require minor
changes to the cowl. The exhaust system generally installs
in less than one day.
Installing a Power Flow exhaust is similar
to installing a bigger engine but at a fraction of the cost,
with faster installation and without the increased fuel burn.
All exhausts have a 60 day, money back guarantee and are warranted
for 1 year or 500 tach hours, whichever occurs first.
In early 2005, Power Flow obtained FAA approval
for a new 'short-stack' exhaust. This popular option offers
similar benefits but with less “distinctive” looks.
Power Flow developed an exhaust for the
Diamond DA-40 aircraft and as of August 2006, our exhaust
is factory standard equipment on the DA40 XL aircraft. We
plan on expanding into the larger Continental engines as used
on the Bonanza and 182 series as well as developing a new
exhaust system for the popular RV series of homebuilt aircraft.
