I have a 2000 E450 with the 7.3L Powerstroke diesel engine. Attached is a 4R100 transmission. Does anyone know what the gear ratios are inside the transmission? Also I am looking for technical data on the 7.3L engine, specifically fuel consumption as a function of torque and engine speed. Also any information which relates engine speed to torque would be a gem to me.
I will worship whoever can provide this kind of information.
The only thing I can help you with is graphs of HPvs RPM and Torque vs RPM. You can go to most any of the tuner sites ie Hypertech, SuperChip, Edge, etc and they will have posted curves comparing stock to their mods. Good place to start. Be patient, there are folks on this site that will answer your questions. This is a great site for technical information and the best part is that we are all users of the products and love these trucks, so the answers are real world, not someone trying to sell you something.
