My setup and numbers are in my signature. Im trying to keep the car in the same power range but reduce lag and increase down low power. I essentially want it spool instantly. I currently have an On3 Journal Bearing 76mm with the .96ar housing. I am going to swap it out with their BB 67mm. Since I already have a .96ar housing I am thinking of ordering the 67 with the .68ar just to experiment. Im only running 6lbs of boost on the 76 so I am below the efficiency range for sure. I think it should be better with the 67. Thoughts?
