ON THE TECHNICAL SIDE Reduced cylinder head temperatures: for every 50° F decrease in temperature the life of a component is doubled. BENEFITS OBVIOUS TO THE CUSTOMER Higher Critical Altitude Broader Operating Range and for a few Better single engine climb A broader operating range means flying to altitude using lower RPM setting and still maintaining MAP. And that equates to lower operating temperatures and a much quieter flight (as much as 3 dB). Pilot choices. Let's look at that broader operating range a little closer in a specific application -- 53% power. We call it Quiet Economy Cruise. Before Merlyn's Control: a 30" MAP, 2100 RPM was only obtainable to 8000 feet. With the control that flight parameter is obtainable to 15,000 feet. For the pilot with economy in mind that equates to a savings of 1/2 gallon of fuel per hour with the same performance obtained at 55% power. And, this is where the 3 dB reduction in noise comes in. A 6% increase in climb. Using 33" MAP and 2450 RPM that equates to 65 feet per minute in the Seneca equipped with the "Merlyn Black Magic" . (40", 2575 = 70 fpm increase) Weather? Along with that nice increase in climb the increase in the critical altitude from 2,000 feet to 18,000 feet is a definite plus that can't be emphasized enough. Gives the pilot a lot of choices he never could have had even with an intercooler. Provides old technical benefits of reduced back pressure, and other things that the pilot doesn't see. The "Merlyn Black Magic" control . only weighs two pounds per engine, doesn't add to the maintenance and gives a wide range of pilot benefits including a real dollar savings, maybe it is magic!
