    1. actually with BBK headers, mid-pipe and cat back. plus BBK is coming out with a throttle body. I don’t see why you couldn’t make 500rwhp. And at least 375tq maybe 380tq.


    1. PI swap = 50 – 70HP, then SCT tuner – 20 -30HP, bolt ons (TB, CAI, plenum, MAF, 24lbs injectors, UDP, fuel regulator + pump), off road exhaust+headers… all that is under 2K if you do the work yourself and your looking at a NA SN95 stang at around 375-400HP that weighs considerably less than an 2011

      by the way minus the off road exhaut thats what my 97′ roush has on it and i dynoed 390HP at 410 ft/lbs


      1. BS no way it makes that much power to the wheels dont lead people to believe they can spend 2k and end up with 400 hp to the wheels


      2. 400Hps not that much.. high flow heads with cams,bigger manifold, with a 75mm Tb and plenum your pushing at least 100-125 more CFM than stock, CAI with a 90mm MAF tuned to 30lb injectors a 255lph pump and 75psi regulator, headers and off-road exhaust, matched with 4.10’s and your ride is set.. unless your starting with a V6 lol then maybe you’ll have some problems.. not to mention a stock sn95’s curb weight is about a little under 3000lbs, where as a stock 2011 GT is somewhere between 3800-3900lbs… so i think it safe to say the properly built sn95 could easily get to 400hp close to 2 grand… you dont have to buy heads and cams BRAND NEW..and thats the most expensive part of the build


    1. @Jose, buddy, or ford, all the best to you my friend. If you have that 2011 stang I envy you right now. 8)


    2. contact kenne bell but it wont be cheap ive got an 02 with a twin screw mammoth and ith put my stock 260 hp gt with other mods at 670 rwhp.


      1. Chris…

        I have 01 Cobra Conv. Been looking at knB twin screw but was being told was only going to take the stock 320 to little under 500. What else you got? I just craxked 30K on her and am turning her into a saily driver/ street race project. Already did 10K audio rework and 2k custom Escort rader.

        So anyone out there wana give advice or thoughts on where to start or direction to go feel free to chime in.


  1. thats rediculous at 6psi… im trying to get 400 out of my 99 4.6 2v w.o boost i wonder if i could come close to one of these after im done putting a vortech charger on it


  2. I haven’t decided which supercharger but this is def compelling.

    What is very surprising to me is not only the 45 degree angle of the whp curve up to redline, but the torque is not far behind the performance of a 8psi Whipple, positive displacement.

    I posted the two charts so you can view here:

    To staff at AmericanMuscle, how would you compare this Vortech at 8psi vs the Ford Racing Whipple 624hp kit at 8-8.5 psi?
