Gear Head Mania Free

Gear Head Mania allows you to build inline 4, inline 6, V-6, and V-8s. The new update also allows you to build V-10, and V-12 engines, and now you can also increase or decrease the turbo pressure to see how it changes the horsepower. As an added bonus, I've also added the option to add transmissions, 4 speed, 5 speed, and 6 speed Auto or Standard. Please leave feedback and comment(s) as to what engines you would like to build. New fixes in update include option to add transmission to non-turbo builds, and minor optimizations.
