Re: IML: 'overdrive' details

[<dansgarage@xxxxxxxxxxxx>]

Hi All...just curious about the 'details' side of adding a 'overdrive' unit to my IMperial (1966), what's the approx. total cost, I assume it also needs a shortened drive-shaft, and from those IML'res that have installed and are using one, what type of gas-mileage difference as well as any difference in acceleration have you noticed (if any!) ?????
thanks all!

It's less about the weight of the car than it is the
stress placed on the driveline.  I didn't go revisit
their website, but I recall them saying that they were
rated to 1200 horsepower or some such stratospheric
number.  If they can handle a hotted-up camaro doing
launches, your dinosaur should not prove a problem. 
They are trying to make this thing work on as wide a
spectrum as possible.

Richard Palme has one in a car that he showed me. 
Works great, and turns your 3-speed into a 6-speed
with an under-dash auto/manual shift option.

Expect to use a mallet or sledge to pound the
transmission tunnel out.  Therefore, you'll want to be
installing it someplace other than a gravel lot, and
perhaps where you have access to a car lift?  Doing
that on jackstands could be precarious.  Get a can od
spray undercoating to seal things up after the
pounding  is done but before final fitment would be a
good idea.  

I plan to put one into a 72/73 coupe behind a HP motor
if/when I find one (please keep your eyes open for
one, folks).  Gear Vendors seems to be THE option and
they are Torque-Flight friendly.
