Funny you should bring that up though; I was in an interesting conversation with Ari from Rotary Performance about the fuel wall that the primaries create because they inject fuel at a 90 degree angle to the airflow. He pointed out that the secondary injectors are at far better angle to flow. With 550 primaries, it is not such a big issue but the larger they get the more of a wall is created. I considered moving the primary's to the LIM but didn't want to screw with making a custom fuel rail at this point.

If my horsepower goals were higher or I was using larger primaries, I would without question move the primaries to the Xcessive LIM.

Thats interesting about the primaries into the secondary on the Xcessive LIM. On another note, I wonder in theory if it would be more benificial to run 4 smaller cc injectors for the secondary rather than 2 larger ones.
