[DML] Re: Torque From Displacement

["content22207" <brobertson@xxxxxxxxxxxx>]

Regarding your last sentence: We've got a saying down South --
"There's no replacement for displacement."

The single best way to get Torque out of your gasoline engine is to
increase cylinder sizes. My 460's have more power *AT IDLE* (500 RPM)
than some small engines have at speed. Max Torque is pumped out
somewhere in the neighborhood of 2-2,500 RPM. They've never seen 4,000
RPM even with a telescope. That's one secret to their longevity --
high rev'ing is very hard on an engine. So too is force feeding it air.

Note that my 5,000 lbs Lincolns can not only propel themselves 0-60
MPH in less than 9 seconds, but they have enough Torque to spare to
pull an additional 5,000 lbs behind (Class III). A trailer does cut
into acceleration somewhat...
