Ok I have a Roush Intercooled super charger on my 2006 F150. I ordered a 2.8 supercharger pulley and I can get a 41b lower. Does anyone know how much total boost that combination will make?
might want to think about fuel pump too. My stock pump was bigger than most stockers but will start maxing out at 400rwhp on my Roush. I currently run 380rwhp and have about 13% duty cycle left @ 8-8.5lbs
