    32# injectors good for 400 rwhp?

    ok so i set my goal for my truck to be 400rwhp, and i have found a deal on some 8.1 truck injectors 32# i suppose, is that enough injector to get me to 400rwhp, or will i need something bigger like 42#????

    svo 30s which are 36 are good for about 440-450 rwhp. so id say 400 420 be the limit

    find some 42s and be done with it if you plan to mod truck down road.

    get a fuel pump and those injectors, it'll be good for now, if that's all you want.
