You're also forgetting one important factor in this equation, the battery capacity.
We all know 2 & 3s is 7.4 & 11.1v respectively, but, are you just changing kv & gearing to keep at your 40mph to determine if your runtime will remain the same?
As Neil said, get a stop watch. Don't take anyone's word for it as we all use different packs, motors & gearing & they all perform differently.
Do the testing yourself & then you will know.
I've done my testing to get my cars to where they are. Yeah, it may have cost me money to buy the motors, but, I just sold what I didn't want & got a decent price for them.
I learnt a lot doing it too.
Good luck what ever path you choose.
