So i am trying to make a hachiroku with a 6.2L and i cant get the gear ratio right, i know its because of the 6.2 so gearing this car is kind of difficult for me. the problem i am having is that when i try to launch the car, the car spike 1st gear really quickly, so i need to change into 2nd gear, but the wheel will still spin and i have no traction. When i do have traction the rpm drop all the way down to 2500 rpm. how do i make the rpm drop to 5000 rpm in 1st gear after i get traction? is there an upgrade that can help me not lose so much rpm?
i got crappy grammar, thanks for reading this.
