Right well one I've been working on:

Aura Cascade + Roguelike Dungeons + Witchery + Extra Utilities + EnderIO + Pams HarvestCraft.

General plan is to turn as much as possible into Aura Power and then push that through fluxing nodes to generate RF.

2x Roguelike Dungeons and 2 Witchery Shrines netted me 2 creeper spawners, 2 enderman spawners and 4 witch spawners, I also use 1 skeleton spawner.

23 block drop onto Diamond Spikes to kill them and drop loot - Momentum pumps produce a little bit of power.

Witch drops: Glowstone dust -> craft to blocks -> Light pumps, Redstone dust -> chained to 15 blocks out then triggered -> Redstone pumps, Gunpowder combined with Creeper's to make TNT (cobble gen and then cobble->sand), Red Aura node, BOOM. Sticks are burned in furnace generators. Glass bottles are voided, potion bottles go into potion generator. Sugar is cooked into sugar charcoal, turned into blocks and burned.

Creeper drops - gunpowder goes with the witches.

Endermen - pearls into ender generators.

Skeletons bones get made into broth, and combined with the witch-dropped spider eyes into the spider eye whatsit. Arrows go towards projectile pumps.

Total power output: Peak around 70kRF/t, average is about 25kRF/t

Breakdown:

Aura power:

1. TNT produces about 2,000,000/min
2. Arrows produce about 75,000/s
3. Glowstone produces about 50,000/s
4. Redstone produces about 30,000/s
5. Momentum pumps - haven't a clue

Total power generated per minute: 11,300,000- however I also use green aura for the pumps, so their effect is nominally quadrupled to give a total of about 39,200,000 power/minute. With all of this I am able to produce in excess of 40kRF/t during the day.

Endermen power:

2x 8x Generators powered pretty much non stop - Once I find a blaze spawner I will be using eyes of ender to up this a lot (basically 4x the burn time) but for now: 640RF/t

Sugar Charcoal + sticks: keep 18 upgraded Stirling Engines running nearly continuously for 1,440RF/t

Potion Generator: minimal, only averages out to a couple of hundred RF/t

Culinary generator: 64x running nearly continuously for ~2kRF/t

I am still tweaking it and will hopefully have a nice design to show off sometime. But I thought I'd give you the highlights
