Hello all, I have noticed that a number of general posts are in reference to milage. I am currently working on that issue. As soon as I have some real data and run time I will post the results. But for now under normal conditions, the real key is to not rev over 2000 rpm. I did a series of tests that show the best milage ( 24 mpg ) will be consistant if driven at 2000 rpm and lower. If some one can figure out how to raise the rear end ratio up a bit to allow 75 mph to be achieved at 2000 rpm that would be ideal. For those that wish to attempt these tests, remember those jack rabbit starts from a dead stop position are not good as rpm's jump well over 2000 every time. Later gang

Replying to: mdamick (May 02, 2009 5:40 pm) What exactly is a overdrive auxiliary transmission? I mean can you elaborate a bit to give me an idea exactly what it will take to accomplish this task. I was thinking more on the idea of installing a taller gear in the rear end if possible. Engines I have no problem understanding and working, I just dont know that much about transmissions. |

Replying to: mdamick (May 02, 2009 5:40 pm) My observation of several types of mechanical assemblies make me say that when a lower torque gearing is used, longevity is increased. What costs us more trouble on the long run? |

Caribou, That is an excellent point, which brings me to the next question. When you have a total break down of a torque converter due to excessive engine torque being delivered to the tranny, What portion of the converter fails due to this condition? I wouldnt think that the little bit of additional ratio necessary to achieve 75 mph at 2000 rpm would change torque converter load that much, but really not sure. Right now I turn 2000 rpm at 70 mph.

Replying to: caribou1 (May 04, 2009 1:26 am) of the converter, and based on that discription I would say that the coupler section of the flange rotor is probably what fails when you here the explanation of a Torque converter sounding like (rocks rotating around in a can) What say you on this??? I sure would like to see a sketch of a cut away view of this beast. I have also heard of something in relation to turbine like fins breaking away internally within the housing. Whats that refering to if you know?? Ok man thanks for the replies and take care until later. Tnilc99
