It would be awesome if somebody would do it and find out.  |
It is possible to run calculations to figure out if the idle governor will be effective with elements 2x the size.. Its not simply a matter of "just try it", unless you want to make it that way.. I just don't know where to start calculating. It seems, theoretically, that as you increase the plunger size, a decreasing variation of the rack position causes a greater variation in the amount of fuel injected. Therefore, if you have bigger plungers, you need a more sensitive governor to compensate... or do you? It basically becomes a function of how quickly the governor can respond to rpm increases/decreases compared to a function of how quickly the rpm increases/decreases with a given fuel input... and a few recursions and recombinations thereof... It seems like if the governor can't move the rack proportionally to the speed of the rpm increase/decrease (that is the rapidity with which the rpms change.. "derivative of rpms"), then the governor can't govern effectively... This data must be available somewhere... after all, the method used for engineering this thing originally was not trial and error...
