is an engine simulation program suitable for everyone from the enthusiast to the university researcher - from the beginner racer to the professional tuner.
You can test your own engine and then re-test and compare your modifications - or build your ultimate engine right on the screen.

One of the features in MOTA is the ability to create and print Expansion Chamber sections, and this is also included in the MOTA demo that is downloadable for free. 
Not all of the functions are operable,  but enough so that even if you do not purchase MOTA you can still create printed patterns of cones and save you having to buy
other proprietary software to do this.   Download it here  .......
