Would these make a good for an engine with over a 100,000 miles? I'm looking at starting to build my GT up this year with my income tax. I'm worried that these might cause problems with my engine seeing that its over 100k.


  • Comp cams has made excellent products for many years and continues to do so to this day, whether the car can handle upgrades depends on many things such as routine maintenance, how the car is driven etc. if done right any car can be upgraded without problem. Just make sure you do your research and either know how to do the cam install or find a reputable shop to help you with it. The mileage on your car should not affect the ability to upgrade it as long as you keep it well maintained.

what exactly do i need if i was to install this product is this just a quick installs or am i gonna have to order different springs or gears?


  • The only thing you would NEED is a tune. If you have a tuner from AM and you have free tunes for life then you are set. New springs or gears are not required. If you have high mileage on your followers and lifters it wouldn't be a bad idea to replace them, but once again, not necessary.

Gains without headers I'd like to get cams at some point, but I'm not sure if I want to get headers or even change the midpipe. Are the gains still good without them or do you really need them to get the gains?


  • I got these cams for my 06 with stock exhaust. Install was super easy and I lost no low end and the car pulled way harder from 2800rpm up till, my new reachable, 6400 rpm. Added a pypes o/r x pipe and I gained even more high end and it sounds mean as a 6 month starving bear chasing you down covered in BBQ sauce with the no cat and comp cam setup. Worth every penny.

  • I went with ford racing cams and already have cai shorty headers ford gt 500 throttle body motion control deletes and axle backs....I am very happy with these cams. As far as the comp cams I think they are similar but I went with ford racing cams. Picked up about 25 hp mostly top end but can truly feel the power past 2500 rpms....Hope this helps

Phaser limiter? Do these cams need require a phaser limiter?


  • No limiters needed. These Comp Cams Stage II XFI NSR Camshafts (05-10 GT) are a simple bolt in part and easy to install with the wedge tool and some patience getting the valve covers off.

    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.

    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.

    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.

    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.

    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.
