Need help changing vehicle speed

[Way2drunk2walk]

I have downloaded a mod truck but it will not reach its top speed. I have tried changing torquescale and maxforwardspeed but it does nothing. 75 mph top speed and best it will do is 42. The only thing that will affect it is increasing max rpm. Am I missing something? Any help will be appreciated.

HI, there should also be a transmission line where you can change the gear ratios. The minForwardGearRatio and the maxRpm determine the top speed. the maxForwardSpeed is like a governor so it will not go faster than that, but the gear ratios determine how fast it is capable of going. If you are using a maxRpm=2250 then to go 75 mph=120 kph you need minForwardGearRatio=7.06 .

The equation is gearRatio=RPM/[speed(kph)*2.653]

That's what I was missing. Thank you for the help.
