I ran the same motor, everything stock with 31's and 4.10 gears and 4.56 gears. 4.56's gears made going up long hills easier and I was able to achieve a higher speed faster. Off road it was better as well.
Hi Mudder,
Yes, you should feel an increase in throttle response with the 4.56 gears. Why?....
Let's say your R&P is 4.10 with 31" tires - you are in first gear and off-road at 6 MPH - your RPM will be very close to 1000 RPM. Your engine is producing 86.8 foot lbs of torque and 16.5 HP.
Now say your R&P is 4.56 with 31" tires - you are in first gear and off-road at 6 MPH - your RPM will be very close to 1100 RPM. Your engine is producing 91.3 foot pounds of torque and 19.1 HP.
So your butt dyno should "feel" an increase of about 5% in torque and HP... right?
I want to do the same thing - "feel" an increase of about 5% in torque and HP only at 80 MPH....
Keep in mind, I'm not looking to chirp my tires going through the gears. I'm looking to simply maintain inertia by dynamically creating more torque to increase momentum in a specific RPM range. In other words, I want more power between 2800 and 3400 RPM in 5th gear. I also want to do the same when in 4th gear at a lower MPH.
Does that make sense?
