  1965 Mooney M20E (Rajay Turbo-Normalized)

1965 was the 1st year of the more modern looking, square window Mooneys and the second  year of production of the fuel-injected 200 horsepower M20E. 

N9GN is serial number 639, the 169th of the 1965 production of the Mooney M20E.  This plane was one of the early planes converted to Rajay Turbo-Normalized with the electric gear modification.  Turbo-normalization has become more popular in this day and age of fantastic graphic engine monitors.  The Insight G1 in N9GN gives the pilot a view of all four CHT's in one picture - they would have loved that in the early days of turbo-charging. 

Early turbo-normalized engines were often short-lived due to their smaller margin between normal operation and detonation.  Detonation is a highly destuctive condition where the fuel more or less expodes in the cylinder causing extremely high cylinder pressure and temperature, rather than an even and productive fuel burn.  Detonation is caused by running high power at too lean a mixture.  Todays graphic engine monitors and expansive knowledge base have operators running these highly efficient turbo-normalized engines rich-of-peak as well as lean-of-peak economically with great engine longevity. 

Please don't hesitate to call us at (303) 503-8356 with further questions regarding N9GN, insurance, finance options, upgrades or transition training. This plane is based at the Longmont Vance Brand Airport in the Denver area and can be viewed by appointment.
