Most TERRIER 200 Aircraft are powered by the Subaru EA 81 engine. In a standard configuration
this engine develops 100 HP, which allows the TERRIER 200 to cruise comfortably at 110 Kts.
A specialised and custom built intake manifold, flow optimised exhaust system, altitude compensated
carburetor and a modified camshaft combined, guarantee excellent performance.
The Subaru EA81 has one of the lowest Fuel consumption in its class at just 13ltr per
hour and offers exceptional reliability.
Maintenance is the second biggest reason customer choose the Subaru, as parts
are readily. And with signifcantly lower service costs that equal to the
automobile industry.
The Subaru EA81 was originally designed & developed as
an Aircraft Engine and then later modified for Automotive use when Subaru
pulled out of the aviation business. The EA81 compact design as well as the low weight/power ratio
makes it a highly recommended power plant for the TERRIER 200.
The cylinder heads as well as the pistons are water cooled providing uniform
cooling even in high outside air temperature conditions as well as during
prolonged taxing and take-off at full power.
Why a reduction drive is needed? As the high performance
Subaru EA81 delivers its high rated 5400 RPM power output a Propeller, in comparison can only spin
and reaches its maximum efficiency just before the speed of sound.
Most customers when enquiring about what engine to choose, are often surprised to read many
success stories from owners around the world that have fitted the Subaru Engine in their Aircraft,
.... and did not realise how many Aircrafts are actually flying with the
EA81.
... extract from
a online article 'Why I chose Subaru':
Automotive engine designs use new methods to increase reliability. They are
very effective. Components are tested in environments far more severe than the engine will
normally see. Computer modeling is accurately done to increase quality margin. I’ve had my hands
in all of this. That helps me appreciate the significance of new auto engine advances. I’m told
that Subaru, in one year, makes more engines than Lycoming has their entire history. That makes
for millions of dollars available for product development that Lycoming can just dream of. More
importantly, auto engines are routinely improved, modified. If Lycoming makes any improvement,
that opens them to lawsuits for all previous designs. So they stagnate. Look how long it took
them to implement fuel injection.
