Attention: TDR Forum Junkies We finished doing the final stages of testing on our TC. I also had a long conversation with Martin Rachel. He writes a soft ware for competitive drag racers that need to predict their performance based on
mathematical formulas.
Most of the Division 6 drag racers refer to Martin as the professor. One of Martin's computer programs can monitor TC efficiency base on mph vs RPM. Unfortunately his current program does not work on the Dodge
Ram because of the lockup clutch. It will read 100% because the TC clutch is locked up at the finish line. Martin knew i was testing my TC for efficiency and re-wrote the program to read TC efficiency at 1/8 mile marker. This way the transmission is in 3rd gear unlocked position and would let me monitor the efficiency.
I realise this doesnt help everyone else but he is writing a program that allows you to monitor your TC efficiency based on RPM drop between shifts. What this means to you is that since we already know what the engine RPM's are,MPH,rear end ratio, and transmission gear ratio are, you will be able to guage how efficient your TC is.
Since this is a mathematical formula based on known factors it will not matter how much
HP you have , what kind of load you are towing, it simply gives you the ratio between engine output and transmission input.
GM, FORD, AND CHRYSLER front wheel drives already use this type of software to monitor transmission and TC slippage. Think of it as a pressure guage for your TC.
If you guys want further info. you can contact Martin @ mrachelis@home.com.
My point is that too much emphasis is on TC stall speed and not enough on the TC efficiency.
