As far as I am concerned is that Fox makes perfectly good sport engines. They ceded the racing and competition engine business to other companies. It would be terribly difficult to compete with Jett or other companies like that.  The Fox .35X combat engines was their last foray into competition types of engines.  But if people want a competition engine for racing or speed or something, they probably ought to look for a different brand engine then, say from Jett for example. Of course with the 2.5cc engine market there are several all out competition engines, such as  Cyclon, Fora, Parra for  example. It is hard to compete with them.
