No, it needs to be removed because it will underdrive the superchargers. I'm sure it can be compensated for using smaller pulley's, but then it starts adding guesswork and would not be representative of the kit's performance. I am debating whether I want to move to a billet aluminum stock sized crank pulley. It's heavier duty than the NST's and Stillen unit, most likely because it's marketed for being usable on supercharged cars as well. I would be hesitant to use my NST pulley with two superchargers tugging at it.
