It's because I'm trying to nail proper custom vehicle stats in a personal Battlefield 1942 mod. Basically, it only asks for Torque and the Final Gear.
Overall, I'm trying to combine the torque/weight ratio and engine RPM into a single Torque value. Assuming that both of my previous engines were geared for the same top speed, I figure the 12000 RPM engine would output twice the torque.
And since the game involves military vehicles, I want to make sure I get the correct torque output since I'll be doing more off-roading than racing.
