The
Right Gears
Paint and bodywork are
the measuring stick that cars are judged by at
car shows and in passing, however, there are a
number of variables that dictate how "good' a
car feels to a driver.
One of those variables that make or break a good
combination is gear ratio. Choosing a gear
ratio for your car is a very personal matter.
Are you interested in fuel economy, power or an
acceptable place between the two? With both
Automatic and Standard transmissions, the ratio
of each gear should be considered for the
outcome you desire.
Automatic transmissions add their own set of
variables to the equation. After a differential
gear ratio change, it may be necessary to change
weights and springs on the governor of an
automatic to correct shift points.
Choosing the correct torque converter is another
application specific variable that is affected
by gear selection and will probably be the topic
of another news letter.
Most people we build cars
for don't have a particular gear ratio in mind
for the build of their car. However, many have
a pet peeve that they would like to avoid such
as over revving on the highway and limited use
of first gear as experienced with extremely low
gear ratios or numerically high gears.
The opposite extreme
would be bogging and operating below the peak
torque numbers of the engine with high gear
ratios or numerically low gears.
One particular build that comes to mind is the
1981 Corvette on our website SelectMotors.Net listed
under current projects. Our Corvette customer
ordered a 425HP 383 from GM and requested a
700R4 overdrive automatic.
He additionally requested that he would like it
to not shift out of first gear immediately like
another vehicle he had built elsewhere in the
past.
The car would receive
custom trailing arms on the rear suspension to
allow for considerably larger than stock
performance wheels and tires.  The
original gear ratio for this 1981 Corvette was
2.86:1, an incredibly high gear or numerically
low. This car needed to hook up on the street
without boiling the tires off the rims and still
pull really hard.
While rebuilding the stock carrier with new
clutches, spider gears and pin, we ordered a set
of 3.08 gears. At the time of the build, 3.08
gears for this particular Eaton type
differential were backordered for 6 months. To
get a base line for a possibly lower gear
choice, we set the rear end up with the stock
2.86 gears.
First gear in a 700R4 automatic is 3.06 which
multiplied by our 2.86 differential gave us a
final gear ratio of 8.75 in first gear. This is
a little bit lower than the stock first gear
ratio of 7.20 with the same 2.86 gears and a
2.52 first gear in a Turbo hydramatic 350.
To go a step further, the 8.75 first gear is
close but still lower than 8.61 which is what
your final gear ratio in first gear would be in
a 1981 Corvette with a turbo 350 and 3.42 gears.
With all of this taken
into consideration, we still had a high first
gear based on today's overdrive transmissions
and typical gear combinations. The Corvette
hazed the tires while pulling hard through first
gear, a perfect scenario for a street driven
Corvette.
Had the customer desired to spend weekends at
the race track, the combination surely would
have been disappointing, where better traction
may have caused a bog.
A different torque converter, different rear
tires, different suspension all would have
produced different results. For our
application, we had the results our customer had
desired.
The TCI street fighter
transmission did require reprogramming the
governor, which we did with a weight and spring
kit.
At Select Motor Company in Ball, Louisiana we
can tune "good" into the combination you have
with a gear ratio and or transmission change.
Drivability
doesn't mean
Getting away with
driving your car
It
means
Your Car
is Fun
