    4 tec fuel question...with a/m intercooler

    im working on my brothers challenger 180, it has the 215... last year we put a prop, cold air, x charger and 42 injectors... ran great all year... my question is, now im adding a gen 1 style intercooler.... will it have enough fuel with this setup, or will it need 50lb injectors, or a rr fuel press/reg? im sure there are alot of skis out there with the same setup.... thanks for info in advance

    You will need a regulator to get enough fuel up top the 42's will be fine. If you ran 50's you would have to take fuel away @ the bottom.

    so you think that set up, with a pressure regulator set at about 60-62 base pressure, would a safe starting point?
