try 113 magmatic dynamos per precharger with one lava fabricator per precharger
you will also need the best type of wires, redstone energy conduits
also, you will need fluiducts
you will, in total, need 4972 invar, but, since you can only make them in packs of 3, you will get 4974 invar
so, for 4974 invar, you will need 1658 ferrous ingot and 3316 iron
I recommand you use an induction smelter, to make it go fast enough, do not use the forge from tinker's construct
so, for the magmatic dynamos, you shall need :
4974 invar (previously told how much that makes)
452 silver
904 iron
1356 redstone dust
makeable, with a pulverizer, an induction smelter, lots of energy conduits, fluiducts, basic knowledge about this mod and minions
