I just read this article in July Kitplanes called Comparing Engines and I 
could not believe it. This guy had two lists of engines. One of auto 
engines and another for aircraft engines. 

He goes on to comparing the power out with various formula ad nauseam for
four pages. 

Give me a break Dave Martin! 

Totally irrelevant! 

Not once does he mention the huge duty cycle differences 
between automotive use and aircraft use. No mention of differences in
internal structure and materials used. This article is a bad and cruel joke.
Come on Dave you should know better by now.

Repeat after me Dave. 

Auto engines average no more than 40 HP continuous!
Aircraft engines average 150 HP continuous!

Auto engines average no more than 40 HP continuous!
Aircraft engines average 150 HP continuous!

Auto engines average no more than 40 HP continuous!
Aircraft engines average 150 HP continuous!

Auto engines average no more than 40 HP continuous!
Aircraft engines average 150 HP continuous!

Auto engines average no more than 40 HP continuous!
Aircraft engines average 150 HP continuous!

Auto engines average no more than 40 HP continuous!
Aircraft engines average 150 HP continuous!

Auto engines average no more than 40 HP continuous!
Aircraft engines average 150 HP continuous!

Auto engines average no more than 40 HP continuous!
Aircraft engines average 150 HP continuous!
