and " DNAMIC " means we are looking to change the IP's timing while the engine is running which means that the heavy fuel lines snaking their way between the IP and injectors act like one big strong spring resisting our effort to twist the IP's body and change it's timing. In a way I like the "turnbuckle" idea especially if a secure enough place on the engine can be found to anchor the other end. Early stage testing for such a tool would most likely tell us whether or not we need such a precise "hold-fast" feature as the turnbuckle. I still think that the inherent strength gained from as much long-arm leverage as practicable will be important in such a tool.

From our prospective here, keep in mind we are thinking of a tool for a profit making mechanic/repair garage trying to check and then easily change the IP's timing, not something that would be left on the engine. Also such "fine-tuning" of IP timing is not likely to be needed that often... should it?
