I would figure that with the injectors below the blower, the engine would be a lot more responsive and efficient during normal driving. But I've seen so many with injectors above. Do the rotors need the fuel to lube or seal them? I was planning on adding an alcohol/water injection system above the blower to provide cooling and chemical intercooling when in boost. My thoughts were this coupled with the injectors at the intake runners would be ideal.

If after that it was just an issue of the front of rear getting more air, to dial 4 injectors up or down a bit isn't a huge issue. But I won't have the capability to getting each one dialed in to the ragged edge. But I think checking the plugs and the header tubes with the laser temp gun should get me there if I edge up slowly.
