Max, as I recall, my DK tranny with the 4.57 R&P and .77 4th gear using 15/215/75 tires cranks about 2850 at 65 mph.Sorry but I was not able to read the whole thread but I"d like to ask if going at 65mph you"d get 2650 Rpm, with 15 inches tires, is there any other way to do a better ratio on gears so it can drop rpm a little more, ,,, knowing now that we"re always driving at least 70 and up on highways it"d be too much rpms and stress on the van??? maybe too much gap between gears?? but a little modding on it and should help if there is too much gap,,
A .70 4th gear would drop the rpms below 2700 at 65 mph. I have the info in an Excel speadsheet but not on this PC.
My gearing is about balanced from 1st to 2nd to 3rd and to 4th.... about 1000 RPM drop between shifts. So, taking the RPMs up to and above 3000 per shift leaves the engine at peak torque (1900 to 2000) for the next gear. (my 3rd gear is a 1.14 vs the 1.23 OE)
70 mph is approximately 3000 rpms with my set-up! ......... more than I would like. But, I'm happy (and the engine/van too) with 65 mph in the right lane
