I suggest you find someone who will let you drive a 5.0 Mustang with
a 5 speed. This will give you a good sense and feel of how a 5 speed will
be in your Tiger. I think my 1988 5.0 Mustang compares well to my Tiger.
There are differences like the Mustang is heavier and the tires are 15 inch
but you will get the idea of how it will drive.

Subject: gears that mesh
O.K., time for a new thread. Even though Bob Hokanson deserves the all
time 'flushing out the lurkers' award, everyone glorying in their dotage is
getting depressing. Bob gets the credit for this one too, since he
provided the Excel sheet for trans calcs on T.U. which prompts my question.
I'm hoping to do a 5 speed , but without a lot of experience actually
driving a Tiger (as contrasted with years of squirming around on my back
underneath one), I'm not sure what I'm seeing in the numbers I get on Bob's
calculator. Steve Laifman, for one, has been effusive about the advantages
of the wide ratio trans in the 4 speed and the various 5 speeds are roughly
identical in ratio to this in 2nd, 3rd and 4th. And since the .80 5th seems
to be relative unobtainium without greater cash outlay, I'll exclude that
for now.
But 1st is more variable. The drop in 1st from 2.32 to 2.78 made a lot
of difference evidently. The drop from 2.78 to 3.35 is even greater. Is it
worth trying to fiind a 2.95 1st gear box? Is dropping below the stock 2.88
rear end ratio with a 3.35 1st gear box a bad idea? My question is: from
a real world [read 'driving'] point of view, what have the 5 speed people
found to be good 'all around' combinations of 1st gear and rear end ratios
and tire size. By 'all around' I mean something that can still embarass the
occasional Porsche off stop lights without hitting 6 grand at 10 mph and a
reasonable agility in daily driving, autocross, and the occasional road race
(not asking much am I?).
Since 5 speeds are still a relative minority, people are welcome to
reply off-list. Thanks for any input!
