I was reading my copy of Automotive Industries and ran across this
chart put out by Mahle pistons. The chart had everything
but I just listed the V8's.
I thought it rather interesting. Notice some cast iron engines are
lighter weight than the aluminum engines (usually with double
over head cams). The Toyota truck engine is probably not far
off thier aircraft engine.
Most of these are light duty engines so the power to weight ratio
means little. The duty cycle is probably inversely proportional
to the power to weight ratio.
(CIL) means cast in cylinder liners.
The volume is in cubic feet which of course is a measure of the
over all size of the engine.
The LS1 Corvette looks like it would make a good aircraft engine
untill you take a look at the materials it is made from.
Cast iron crank shaft and powdered metal rods are the
big stumbling blocks. So far to my knowledge forged
crank and rods are not yet available for the LS1.
Same goes for the Cadillac.
Notice GM does not put this engine in thier trucks.
I think there are weight errors in this chart for some of
the larger GM diesel and truck engines.
The 3.9 Ford Dohc engine in the Lincoln LS is probably
the same as the engine in the Jag XKS. A real nice engine.
My favorite car in fact. Puts out a lot more power in
the Jag.
