    Review & Install Video

    Hey, guys, Adam here with Today, I'm bringing you a detailed overview of the Comp Cams Stage 3 XFI NSR Camshafts, available for all 2011 to 2014 Mustang GTs. So, in this video, I'll be going over the sound and performance gains you can expect when adding the Stage 3 Comp Cams Camshafts to your own GT Coyote motor. Now, of course, with that, I'll be talking about the installation, which I'll tell you upfront gets a full three out of three wrenches on our difficulty meter, will definitely test the toolbox, and take some serious mechanical expertise to get the job done. The Comp Cams Stage 3 XFI NSR Camshafts will be for any '11 to '14 GT owner looking to get the highest gain possible from a set of camshafts, like these Comp Cams offer right here. These will be a maximum effort camshaft for those guys out there with the full bolt-on Coyote motor looking to really beef it up a bit more. This will be something that you don't need to pick up a bunch of extra parts for, hence the NSR or no springs required title here, and, of course, that'll make for a little bit of an easier install. Now, one of the great things about this particular Stage 3 set is it's perfect for either naturally aspirated or force induction Mustangs out there with the Coyote motor, and, again, full bolt-ons are definitely required here. I'll talk about that in just a bit. But I also wanna mention it's great for street and strip application, so you get the best of both worlds here. Giving you a lot of top-end power, this is definitely something out there for the guys who are more concerned about power, less concerned about sound, which is really something that goes along with the Coyote motors. After all, it's not really a pushrod, so you're not getting a deep lope with any of these cams available on the market today. So, to further elaborate on what I said just a second ago here, this is something that is going to be perfect for the guys out there with the full bolt-on Coyote. Now, what exactly I mean by that is, you know, long tube headers, 373 or steeper gears, a Phaser Limiter Kit, and really tying it all together along with some other mods. You definitely wanna pick up a custom tune to maximize the full potential of everything you got going on. Now, as far as the power adders, it's coming in at the top end of the RPM band at the maximum pure 5500 to 7200 RPM range on the power band, something that will perform with the top-end power and, again, works perfectly with a lot of other bolt-on mods. As far as the pricing is concerned, you'll be looking at spending about $1500 for these particular set of cams. Now, even though it's a no springs required set, the install is not like those old single-cam pushrod motors that cost a couple hundred bucks. This one, if taken to a shop, will cost well into the quadruple digit region, which is to be expected, considering how in-depth the four-valve motor cam swaps are. This is a well worth it price tag for those who are more interested in the power gains that a set of this Comp Cams will provide on top of your full bolt-on build. Just to give you an idea of what exactly you're working with here, expect the intake duration at 276, the exhaust duration at about 283. Intake valve lift comes in at 0.492 and the exhaust around 0.453. Now, of course, you can check out all the specs on the website or the Comp Cams and even the listing in the box when you get the package in the mail. But shifting over to the install, I wanna mention that it does get a full three out of three wrenches on our difficulty meter, something that will take a better portion of a day, mechanical expertise definitely required or at least somebody around you who knows what they're doing, because it will test the toolbox and require a lot of digging into the engine bay. Now, of course, after the better part of a day, you will get top-end power, something extremely noticeable, especially with a custom tune, which, after all, will tie everything neatly together. Well, just to wrap things up here, if you're the owner of an '11 to '14 GT and you're looking to pick up some serious top-end power as far as gains are concerned, and you really wanna get the maximum effort out of some camshafts, you might wanna check out the Comp Cams Stage 3 XFI NSR Camshafts, available right here at

    Street and Strip Cams. If you're looking to get serious upper RPM gains, but don't want to add springs, a set of Comp Cams Stage 3 NSR camshafts are the perfect addition to your Pony. If you've already added long tube headers and 3.73 (or steeper) gears and are now ready to take the next step, the Stage 3 Cams add big power gains for strong power gains above 5500-7200+.

    No Springs Required. These cams are compatible with your factory valve springs, so there's no need to remove and replace your 32 stock springs, saving you time and money.

        Supercharger I have the Ford Racing 624 supercharger, full header exhaust and GT Track Pack. Will this be to much on the engine?

        • You need the cams that work on a blower set up

        i have a 2014 gt cold air intake,85mm bbk throttle body, BBK 1-3/4 in. Ceramic Tuned Length Shorty Headers would ireally need to get long tubes

        • These DOHC Comp Cams Stage 3 Camshaft require the use of 3.73 or steeper rear gears and full length (long tube) headers, as well as a phaser limiter kit and custom ECU programming. Reason being is the cams will be pulling in much more air and in turn releasing much more exhaust gasses, in order for the motor to breathe efficiently long tubes would be required.

        I currently have the ghost tune. I was wanted to know how does this cam sound. I'm looking for that rough lopey idle. Like the old hot rods.

        • The Comp Cams Stage 3 XFI NSR Camshafts will have a rougher idle, but will not be as lopey as a ghost cam tune.

        I have a 2014 GT with an Air Raid CAI, 3.73 gears, and BBK Ceramic Long Tube headers. Which Camshaft will give me the best hp gains and jump in the 3,000 to 6,000 rpm range? I also have a tine.

        • The Comp Cams Stage 3 XFI NSR Camshafts are designed for the 1900-7200rpm range. Stage 1 will work best in the 1500-6800rpm range, and the stage 2 will work best in the 1700-7000rpm range. We recommend The Stage 3 for your setup with a manual transmission. For automatic equipped cars, we recommend the Stage 2 camshafts.

            No lope. Sounds stock at idle.

            Spend your money on forging your rotating assembly. Go with a supercharger. I think I picked up around 40 hp above 5500 rpm You can make 1000 rwhp with the stock cams. The coyote thrives on boost.I wish comp cams would had told me that these stage 3 cams sound stock.The guy from comp cams told me that I would have a choppy idle. Not worth the $2500 for the cams installed.

            cam swap 2013 GT

            The cams work very well. The power band begins around 3200 rpms. Great top end, the car pulls hard to 7500 rpms. However a stall converter is badly needed. other mods include the cobra jet intake manifold and twin 65 mm throttle body. The exhaust is still stock except for some bolt on Outlaw mufflers from flowmaster.

            Worth every penny be aware some good tuners can tune without limiters cough cough. I'm not going to say who. But these cams are worth the money. And are worth 30-40whp depending on other supporting mods
