UPDATE: Excel sheet on R&P Gear Ratio x Tire Size x 4th & 5th Gears, with torque numbers.
I will convert it to a JPG for you know who tomorrow.
These torque numbers are for my rebuild as I see it in my DD.
I only calculated 31" tires and 33" tires, and for 4.10s, 4.56s, and 4.88s, and driving in 4th gear and 5th gear.
The numbers and math clearly confirm what R&P you should consider for maximizing best torque in the RPM range.
That sheet is about 4.5 hours of work on the computer!!
Gnarls.
You need to take into consideration the tire diameter tooo.... (not just R&P X torque)
