I have found some info for changing rear gears. thought i would post for anyone else that might find this useful:
i have 3:31 gears and at 120 km RPM's are at 2000. i was looking to change the gears for more out of the hole gump..
so moving from ( 3:31 to 3:73 ) = 1.1269 multiply by 2000 rpm = 2254 your new rpm for the higher gears or
( 3:31 to 4:10) = 1.24 would be 2480 RPM at 120 km.
i'm sticking with the 3:73 not that i'm worried about fuel mileage, but rather don't want to be too hard on the engine with the long trips i plan on doing .
i know there are charts out there, but they don't take into count the rim and tire sizes on your cars, so this math will be correct for your ride.
