I frequently came across that logic in my last job. Would you be
willing to spend $500k on software for an independently proven saving
of $5m over 3 years - it is staggering how many companies aren't.
In this case, although the engine price would clearly be less for the
LS1, this is a tiny part of the running costs over the 2000 hour life.
Fuel is the biggest cost by far, and diesel has a proven 30-35%
efficiency gain, so the savings get better as fuel prices rise.
Savings today in fuel costs over 2000 hours for a diesel should be
about $70,000.
Saving is about $4,000 for every 10c rise in fuel prices, and I expect
we will see prices rise another 25-50c this year.
Costs are at the stage that an engine manufacturer offering a free
engine for using their fuel is an interesting idea !
However, the LS1 is a far better option than continuing with the
Lycoming !

Hi Peter
It is unlikely to be cheaper to buy, or run, than an LS1 V8 -
replacement
cost A$6,000.

Subject: [Aus-soaring] RE pawnee engine option
Centurion have a diesel/jet A engine available and EASA certified for
replacement in the Cessna 206. It is rated at upto 350 hp with some
derate
for contnuous operations
I wonder what this would be like with a fixed pitch prop and
retrofitted in
a pawnee. Business case would be interesting.
