    Supercharger Would it be ok to run these before I put my supercharger on?

    • Yes, but just make sure you re tune after you install them , and retune after you install the Supercharger . Just don't expect any super gains until you install the supercharger, since the cams are made for one .

    Can you help me figure out if these will fit my FGX XR8 (in Aus) 2015 model factory supercharged coyote 5.0?

    • These have not been tested for fitment on the AU models.

    I see for the N/A comp stage 3 cams you “need 3.73 or higher gears” so 1: why do you “need” those? I have 3.55 now and don’t want to have to buy another set of gears and another install. 2: since these are the blower cams I wanna run these bc I will go that rout in the future and I’d like to run these cams now (FBO) and then get the SC but will I need the steeper gears for the blower cams? Sorry for the paragraph

    • Due to the RPM range and power the cams are designed for, they work best with 3.73 or higher gear ratios. While these can be used with 3.55's, they will not perform as intended by Comp Cams. These cams can be used on a N/A motor, but power gains and performance will not be ideal, as the profile is designed specifically for a supercharged engine.

    Will these give me a nice loopy sound?

    • The Comp Cams Stage 3 XFI NSR Blower Camshafts will give your Supercharged Mustang a nice idle, more aggressive than stock, however this will still be a relatively mild idle.

    Will these cams fit 2015 5.0 mustangs? they are not in the 2015 - 2017 5.0 options.

    • Unfortunately these cams will not work with the 2015+ Mustang GT models.

    I'm looking to turbocharge would this cam work or should I go with the NA cams 1 answer
    Are these Mustangs Rollers or Flat Tappet? are these cams for one or the other? 1 answer
    OK, so not expecting any "super gains" while installing these cams prior to a S/C, what gains could one expect to see? Ballpark, I won't hold you to any hard numbers. 1 answer

      Awesome cams

      Nice power gain over stock. Work well with Roush blower. Sound good at idle. I had my shop install these while my motor was out of car and getting rebuilt with forged bottom end.

      You want a Loop idle?

      My wife bought this cam for her 2014 mustang gt. She had me install a S/C on her car few weeks back. The cam helped gain max HP out of the super charger.
