[A/S] Re: tow speed
Jim,
If you go to the "Files" section of the list I just put up an Excel
spreadsheet that will give you actual speeds at indicated and speed to
indicate on your speedometer to get desired actual speed. Without
knowing the normal rpm it's hard to say what the new one will be, but
mathematically its about 14% higher at the taller gear ratio.
As for towing in overdrive, I just kick the overdrive switch to lock
it out when I'm pulling a hill and the truck (F-350 PSD) downshifts.
When I crest the hill I let the overdrive engage. The real killer is
the constant shifting in and out of OD. When towing I'll set the
cruise to the posted speed limit move to the right lane and let the
world just fly on by.
Of course in my part of the country that posted limit is 75 in some
places, which can exceed the comfort level of some towing drivers, me
included, so I do have a limit.
