"Decorum": The standards and mores of polite society. You often write
somewhat boorishly (Message #15162 for example -- Googled that one on
"are an idiot") an unfortunate characteristic that will hopefully
diminish as you age, for your own benefit if no one else's.
"Redline": This is not the point of maximum power output (as your
recent DML reply Re: optimum shift points claimed). It is the point
after which an engine absolutely produces no additional power. Rev'ing
an engine past its redline truly does "make nothing but noise"
(provided the valves and ignition are even still working). 99.9% of
the time an engine will reach its maximum power output long before the
redline, on the downhill side of its power curve.
"Horsepower": Everyone else in the world calculates as:
Torque x RPM / 5252
(Please feel free to look it up). This universal definition allows any
engine to be compared to another. Rudimentary mathematics: you should
never quote a calculated HP result without also quoting either the
Torque or RPMs at that point of engine activity. To do otherwise is
totally meaningless. Is like saying "these beans cost $1" (obviously
leaving out such pertinent details as the size of the can...)
