TE 3 Problem: Charcoal into dynamos or Steam into dynamos

so, I'm just wondering, is it better to feed charcoal directly into steam dynamos or is it better to feed them into steam boilers which then powers the dynamos for power. It seems like in 1.6.4 even a 16x16 ghostwood tree farm can't stand the usage of charcoal from more than 7 36HP boilers. I have 6 HP boilers set up right now and my charcoal supplie is barely growing atm.

BTW come on why did railcraft get nerfed so much in 1.6...
