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.
