Performance is based on a mid CG with mid cabin and fuel weight on an average day. Performance should always be calculated per flight environment while referring to the Manufacturer’s Pilots Operating Handbook and applicable Flight Manual Supplements for the particular airplane. Aircraft Manufacturer’s Pilot Operating Handbooks and Aircraft Owner’s Manuals should always be available and adhered to by the aircraft Pilot in Command, including attention to applicable FAA approved Flight Manual Supplements and emergency procedures for each individual aircraft. Performance should vary from airplane to airplane, atmospheric day to atmospheric day, one gross weight and CG to another, and pilot to pilot.

 
   
Larger Turbo - Larger Intercooler - Improved Cooling  
TA81 Airesearch Turbo: 17in³ Compressor - (vs. original 10in³)  
Larger Intercooler - 140in³ - with improved construction  
Split Scoops - optimize aerodynamic efficiency, RAM’s dual passages provide one passage for induction air, and another for intercooling air.  
Larger cowl flap - streamlines exit of engine cooling air, hot air exit area is increased to 78in² vs. original at 26in².  
Maximum Continuous Power - 325 hp to 25,000 ft.  
Cruise Power at 75% - 251 hp to 30,000 ft.  
RAM’s Series VII Split Inlet Scoops streamline air flow with minimum aerodynamic drag.  
Larger Cowl Flap matches the additional ram-air intake. Compaction of cooling air is
substantially reduced by RAM’s larger cowl flap optimizing the exit of hot air from the engine and intercooler.
