    I have an 07 Saleen Mustang 4.6 3v na . I have 115k on the motor (yes I bought it to drive). With this much mileage and bigger cam, would new internals be recommended, ie. springs, lifters, followers, bushings, etc. Have kept up with the maint., full syn. oil change every 3k miles.


    • As long as you have keep good care of your car your stock internals would be fine with a stage two cam. However it is never a bad thing to replace your stock internals!

    I'm planning on upgrading my cams in my 05 mustang GT , I don't like that choppy sound do these cams have that sound?


    • The Comp Cams Stage II XFI NSR Camshafts will have a slighty choppy idle like stock but will not have an aggressive muscle car cam lope.

    Can you add boost to these cams, like a procharger or supercharger? Or will I need different cams later?


    • We would recommend specific camshafts for forced induction applications for the best results, however, these Comp Cams Stage II XFI NSR Camshafts could technically be used with a proper tune. We would highly recommend speaking with your tuner regarding you application and if these camshafts would be a suitable modification for you turbocharged or supercharged application.

      Yep yep

      I just couldnt see myself paying the shop 700 to or more to no mechanic but i can say that i did it. Took me 2 weekends to get it done but hay, i had to work. Now it runs great and i dont even have a tune on it just yet. Im on 3.55 gears but i also have a paxton supercharger. The sound is pretty close to stock but thats not why i bought these cams, only needed the power that came with it. Nobody will know you have these in until its to late.

      Great mod and sound.

      Installed relatively easy. Took about a full 12 hr day. But I also added ford racing intake manifold and 39 lb injectors. Make sure you get a dyno tune when done. It will run and drive without one. But after the tune it works better than new. Sounds amazing. Just what I wanted

      Heyyy that's pretty good.

      Hella better top end torque, feels like vtec kicked in. Decent lope, deeper exhaust note.

      Awesome high rpm cam

      OK so her me we go!! The first thing is you would not want to go with the brenspeed Detroit rockers my friend has an 08 with that exact set up and cannot touch me with these cams . My last rUn before I put these cams and an off road x pipe was a 13.6 and the day I finished my cams I put down a 13.0 on street tires that spun BADLY that's with an auto trans, 4:10 gr candl racer intake frpp 62mm throttle body slp muffler delete and these cams that's it. For bus auto guys you do not need a stall but if you have a loudifferent exhaust it I'll bog up to 3000 rpm's and be a little annoying you do need to have the 4:10s if you want these cams but over all I havnt lost to an 05-09 from a roll on the street since and I believe with no spinning I could run 12.8 or bettter

      Stage 2 nsr cams

      When j bought the cams I really was expecting a little bit of idle, but after installation I was very disappointed as the idle was almost indistinguishable from stock. Torque loss was sufficient as to be expected from cams but top end gains really pulled hard. I have 373 gears but it didn't fully compensate. Overall if I could go back I would have gotten brenspeed Detroit rockers and 4.10 gears.

      These Cams Rock!

      These cams are real agressive but not so much where its not streetable. I was very impressed with the purchase and not having to buy springs and lifters really saved me some time.

      couldn't be happier

      My 2006 mustang already has bbk long tubes, offroad x-pipe, cmdps, underdrive pulleys airaid intake with no restricter, gt500 tb and 3.73 gears. I wanted a set of cams to give me more power but didn't want the loping idle, so i decided to give these a try.I couldn't be happier with the results. My car idles great with just a hint of a lope,drives like stock at all rpms and really starts pulling at 3800. If i did lose any low end torque i really can't notice it and i installed a ford racing intake at the same time as the cams, so any loss could be attributed to the intake anyway. Beat part is my car still drives around town like it did before the cam swap, just pulls a lot harder the whole rpm range.

      08 GT comp cams

      These cams were pretty easy to install, but if you're putting the phase limiters in with them, it's an added complication. The sound is great, really aggressive with LTs and o/r mid. It feels like I lost a bit of torque on the low end, but the high end gains more than make up for it. 0.5 second gain on the quarter, though I put LCAs in at nearly the same time.

      Great product

      Easy install (as long as you have the wedge tool). You can feel a huge difference in the mid and high end. The power feels more uniform and now doesn't have the lag like it used to.
