Great product, small loop sounds and runs great. Get the power and don’t have to worry about that loud chopping soundHelpful (1)

Almost no lope, but so much power
No idea what I’m making to the wheels, but I have long tubes, off road H, cold air intake, tuner and borla axle backs. The power is unreal compared to stock. I’m definitely gonna add gears next. It’s a bit ruff in first gear. Only thing I’ve raced since install was a focus st with a few mods. It wasn’t even closeHelpful (0)

Idle or not!
I had already installed the “mother thumper cams”, loved the thump, lots of heads turned, great power, sounded incredible by lost the drive ability. I always had to keep it above 1500 rpms or it bucked horrible, they cams still gave me great hp gains, some idle, but now I’ve got my drive ability back. Both cams are great, it just depends on what you want in the end.Helpful (1)

Do you like to feel your gains?
Grab a set of these stage II nsr cams by comp cams. The idle lope is very mild so you will leave most of your competition scratching their heads. These make the top end come alive and are an excellent upgrade with no real changes to the low end power. If you want good power gains from a set of cams but don't want much attention due to an obvious muscle car lope these are the cams for you.Helpful (3)

Best mod for your GT
I have a 2006 GT with an aftermarket CAI, TB, intake manifold, long tubes and off road x pipe, underdrive pully, and 4.10s and was seeking a mod to tie that would really pull these all together and this mod more than delivered. You can feel the added power, especially in the upper RPMs and I think it certainly added every bit of the quoted HP amount and probably more with my other mods. Some people say they noticed a low end loss, but with my 4.10 gears, I haven’t noticed anything like that. The best part though is what it does to your exhaust note. I didn’t want something overly lopey and while this give a SLIGHT bit of lope the idle is music to my ears. Paired with my Roush muffler delete catback I have not heard a louder mustang out there. It roars. All in all I strongly recommend this mod once you have the other supporting cast of mods in place. It’s the best way to get the most out of your NA stang.Helpful (5)

I just couldnt see myself paying the shop 700 to or more to install...im 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.Helpful (9)

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 wantedHelpful (7)

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 bettterHelpful (6)
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!
would it be safe to put these cams in with and ever day car with stock heads? I want to put these in my 05 GT but I want ti make sure they wont tear up my car. Is it safe to put these in a car with stock heads?
They are fine in stock heads and won't damage anything
Do these cams require comp cams phaser limiter kit?
For These Comp Cams Stage II XFI NSR Camshafts (05-10 GT) there will be no limiters needed.
Do these stage II cams have a muscle car lope?
The Comp Cams Stage II XFI NSR Camshafts will have a slight idle from stock but will not have an aggressive muscle car cam lope.
What all would I need to install these cams?
You will need at least a 2500 plus stall speed converter and you will not lose power with those gears.
The Comp Cams Stage II XFI NSR Camshafts will have a more aggressive idle than stock, however if you are looking for a very lopey idle above all else, offerings such as the Ford Performance Hot Rod Cams, and Comp Cams 127020 would be a better fit.
These are designed specifically for 05-10 GT Mustangs and will not work on any other vehicle.
The Comp Cams Stage II XFI NSR Camshafts can be used with a supercharger, however we would recommend cams designed for supercharged engines to get the best power gains.
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.
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.
The Comp Cams Stage II XFI NSR Camshafts requires the use of 3.73 or steeper rear gears and a 2500 plus stall speed converter for automatic transmissions. If the stock converter is used, the car may lurch forward when not expected to. In addition to the gears and converter, your vehicle would also require a new tune. We do not carry a 2500 stall converter, but many enthusiasts enjoy TCI's converters.
The Comp Cams Stage II XFI NSR Camshafts requires the use of 3.73 or steeper rear gears and a 2500 plus stall speed converter for automatic transmissions. You will need an updated torque converter.
The Comp Cams Stage II XFI NSR Camshafts would be a good choice seeing that they provide great low to mid range power gains.
No, these are designed for a GT.
