19 May 04 - "The bottom line is more horsepower at all altitudes" Plane & Pilot magazine has published a feature article in its June issue, detailing the efficiency and performance of our Power Flow tuned exhaust system together with Laminar Flow aerodynamic modifications on a Piper Cherokee 140. The article provides testimonial from a satisfied client as well as technical figures to back it up. The airplane’s results, after installation, included a 200 fpm improvement in climb performance as well as a max cruise speed increase by 12 knots. Bill Cox further states that Power Flow Systems and Laminar Flow Systems is known for extracting uncommon performance from unlikely candidates.
