E55 AMG needing more boost!
My E55 AMG 2004 already has rentech CF intake, bigger heat exchanger,water pump upgrade, and 168mm Crank pully.
I would like to increase the power more and i was wondering what other supporting mods i need to allow me to run the extra boost from a smaller 84mm supercharger pully that will give me an extra 1.5-2psi more ?
at the moment i am thinking injectors? but what size? brand? and will they be drop in or require custom rail and wiring needed?
any recommendations would be great.
regards
