Hey guys I need a bit of help with car physics type thing. I am trying to create a simulation of a car moving in a straight line. I have been searching the internet for two days but have not been able to find much.

I want the user to input the cars torque and then on a little simulation the user presses up and it does exactly what a car would do if you pressed down on the accelerator.

I need some help thou. What I have figured out lately is things live
velocity
acceleration
mass
momentum
torque
rpm
horsepower
force
energy
air resistance
friction

but I want to completely simulate a car on a road with air resistance. I have tried and tried but my figures are not. I need some formulas like how to convert the energy into speed and how to convert horspe power into energy.
I have a formula for converting torque and rpm into horsepower but I have no idea how to convert torque into rpm. Any help would be appriciated. Thanks
