Power Flow recently shipped its 3,600th Tuned Exhaust System to a Cardinal RG owner.
Power Flow officials note that most four- and six-cylinder Lycoming and Continental engines rarely develop the full horsepower for which they are rated due, in part, to the design of the original exhaust system. The exhaust gases from each cylinder often interfere with each other, inhibiting smooth flow and reducing engine performance in the process. Power Flow’s Tuned Exhaust Systems are designed to increase engine efficiency by drawing out the spent gas and leaving more room for the next intake motion. In a word, they “maximize” an engine’s performance, bringing it much closer to its rated horsepower, according to company officials.
Power Flow has received STCs for such popular Lycoming-powered aircraft as the Cessna 170, 172, 175, 177 and 177RG (pictured). It also has STCs for the Beechcraft 23 series, Diamond DA40, Mooney, and the PA28-140. Final FAA approval is pending for the Robinson R22 helicopters and the Aviat Husky. Development is also underway for the Beechcraft Bonanza.
In each case, the owners experienced an increase in cruise speed, greater rate of climb, diminished fuel burn (at cruise settings) and shorter takeoff runs. “In some ways, it’s like upgrading to a larger engine,” said Darren Tilman, general manager for Power Flow. “You get more torque and better performance to increase your aircraft’s utility, but you don’t have to deal with the extra weight, or anything close to the cost of a bigger engine. Plus, a new exhaust system can be installed in just a few hours.”
The company offers a 60-day trial with a no-questions-asked, full refund return policy. In cooperation with Power Flow’s “Preferred Dealers” that 60-day trial period covers labor charges and shipping. There also is a one-year/500-hour warranty.
