    8 inch Crank pulley Clearance

    I will be putting on the 8" crank pulley soon and would like to know before hand if there is any clearance problems being experienced while installing. Anyone?

    You running the single belt or dual belt Novi??

    Single belt, you'll need the smaller Cobra w/p pulley (~$25 from Ford Dealer)

    Dual belt, no clearance issues.

    I have the new style...BTW how much boost wii I be seeing with just the 8" and a powerpipe? Can a F-150 puley be put on the new novi?Basically I would like to see around 9-10 of boost with out voiding the warrenty, can it be done?
    Another question is, I have H,C,I along with 24lbs injectors and a 190lt pump, what should I jump to in terms of injector size to compensate for the increase of boost?
    Thanks for help!

    Most of the guys here are getting in the 10# range with a 8" and power-pipe on the new Novi.

    Most of us with H/C/I jump to 42's and an in-tank 255 Walbro Hi-Pressure, some run an additional in-line pump as well. You could get by on less injector @ 10#'s but the 42's are pretty cheap when compared to some of the smaller injectors.

    Whoops, missed one...No you cannot use a F-150 pulley on a dual belt set-up.
