By the time you have gotten to the point where you have the materials necessary to create a stable supply of jetfuel, as well as tungsten to make the turbine, you could easily have built a big reactor setup that produces the same amount of power. As to the way it was calculated, i believe it was to do with the amount of power a real world lava 'block' could make, compared to what it costs to make in a lava fabricator.I'll take my point here.
I suggest you rethink the new power conversion rate. I could post dozens of examples, but it what comes down to is that this is in no way even near to balanced. In no way does the output of a gas turbine (my knowledge is 67MW) equal 129 KRF/t. I've powered an extractor with 67MW in the past, and I can do comparable things to what the extractor does at that power at comparable speed with other mods not usually accused of being OP using a tenth of that power. I say this is utterly, completely unbalanced, and it comes across to me not as a necessary rebalancing, but as a 900% import tax on imported power, in order to make power imports economically unfeasible as well as difficult to achieve.
I would like to know what went into the calculation on your end? Maybe there is a point I can't see, but judging from the end result I would conclude there must've been some mistake.
The only thing I think is wrong with the current RF integration is that rotational dynamos are to easy to make, and gaining quite significant free rf off steam engines in the early game is too easy. Maybe include tungsten in their recipe?
