I've been playing Minions of Mirth for a while now and do a fair amount of enchanting. I have a hard time remembering maximum statistics and relied on Minion Tools, which is no longer available. I gathered the information I could find from the forums where they had posted a snippet of the code, http://www.prairiegames.com/trac/mom/phpbb/viewtopic.php?t=9385&highlight=mom+formula+enchanting and figured I'd make it readable.
The following table is for Level 100 equipment. It should be noted that this goes by the base requirements of the crafted item, and a few classes have no item available to be crafted at that level.
It looks like you can find the maximum statistics by using the formula: Max(level) = Max(100)*(level/100)^2
