Hey! Yeah, i just put up a good engine simulation system, its not realistic, but it focuses on being as close as it can be, im no engineer (yet, first year here)
The system im "developing" simulates torque, by separating each wheel axis (front and rear) so there will be oversteer and understeer.
I also found a way to simulate higher torque on higher RPMs for competition cars and a higher torque on low RPMs to simulate muscle cars =D
At the moment, and when i release it, probabily only the XRT will be playable (the others may be selected but wont work)
other than this, graphically it's the same. i may later create objects with collision and implement the mouse so the objects can be created and moved with the mouse. =D
