Hi,
you will experience about 40 rpm increase for each mph over the stock gears. Tire size also plays into the equation. Your final drive ratio is probably .75 give or take a little. Highway rpm will increase as your drive shaft will turn 4.1 times per revolution of the tire compared to 3.2 which is stock. 4.10 could be to much depending on your choices of drag/sreet or combination of both. Do your research as each .25 change in ratio is about .2 to .3 in the 1/4 mile......
There is a break point where more is actually less..........good luck and have a blessed day!!!!!!!!!!!!!jim
