Moreover, the new PT6 requires no anti-icing fluid (Prist) in the fuel, as it uses excess turbine heat to eliminate ice. The result is cost savings and decreased hassle for pilots. Strangely enough, Cessna isn’t the first company to add power to the Caravan. Blackhawk, among others, has been making this modification to Grand Caravans for a while and selling a lot of them, using the P&W PT6-114. Texas Turbines and Aero Twin make Honeywell TPE-331 conversions that go beyond 900 shp. The Grand Caravan EX, however, marks the first substantial Caravan power boost from Cessna since the Caravan’s inception almost 20 years ago.
