[Tempest VI]

I've overhauled my CA AUG's mechbox with one of those Guarder SP150 FTKs but swapped out the spring with a M120. I knew it was going to lower my ROF and such because the gears are "Infinite Torque", and the AUG runs a 8.4V mini. My ROF is currently at around 2 rounds per second. Now, I do have experience with LiPos but only in helis, but that's a different concept than an AEG. I know the more volts the faster the motor is going to turn, the thing with helis is that rotor rpm is always 100%. From what I read on the forms, the 11.1V LiPo won't alone increase my ROF and that it will act similar to a 9.6V? I know I can also change my motor to something like an EG1000. The motor I have currently is stock and it just says Classic Army, but apparently it may already be an EG1000, as some other threads said CA now puts those in their newer guns?

So in essence what I'm asking is what is the best possible way to increase my ROF in my current situation? If going to a 11.1V LiPo won't do the trick, what will? Theoretically, my mechbox should be able to handle it without any problems... right?
