Description
Serious Cams for Serious Performance. If you're looking for a high lift camshaft for a highly modified street Mustang, these Comp Cams Stage 2 XFI VSR Camshafts are your answer. This serious street cam delivers big gains on highly modified cars with a noticeable idle. May not be street legal in all areas, please check your local laws.

Big Gains for Modified Engines. We've heard of 30+ horsepower on modified vehicles with these cams. For these monster cams, you'll need new springs and get the best results with 3.90 rear gears and a 3000 stall speed torque converter.

Compatibility. These camshafts are designed for the 2005-2010 4.6 and 5.4 Modular three valve V8 Mustangs. These cams require a spring upgrade and tuning is recommended.

Tech Notes:

Note: Want less extreme cams? Consider Comp Cams' Stage 1 cams. Got gears & converter but don't want to buy springs? Check out the NSR cams.

Technical Note. The installation of these Comp Cams will require a phaser limiter kit and custom ECU programming.

Custom Tune? If I have free tunes for life will AM be able to tune the cams with a e-mailed tune?

    These Cams are GREAT!

    I dont know about the last guy but when I installed these cams on my Procharged 05 GT I saw a HUGE difference in power just like AM says. The reason the last guy didnt see any gains was because, although he had a lot of aftermarket parts these cams require engine mods, not just bolt ons. I am running bigger injectors, coils packs, a procharger, throttle body, and a custom tune. My car is reaching into the HIGH 10s with this cam and the procharger. I would HIGHLY recommend this cam to anyone looking to put some pep in their step. Thanks to AM for the quick shipping

    great bang for your buck

    to the guy above me. sounds to me like your cams are not timed right and possibly during the install that your cam timeing chains have sliped off the sproket at the crank. theres now way that you should be going slower at the track after cams. you should have your cams timeing checked. check the timeing marks on the phaser and chain and make sure postion1 is at top dead center to see if all is where it should be. hope this helps you out and any one who want to do cams to there mustang. i have stage 2 cams in my mustang and they are awsome :) puting down 380rwhp with the stock heads

    DONT WASTE YOUR MONEY!!!!!!

    I have all the supporting mods long tubes, Ford racing intake manifold, bbk 62mm tb, c&l racer cold air, tci 3000 stall, 410 gears, aluminum drive shaft, msd coil packs. All these part were bought from American muscle I will add. Before I added the cams I was running 12.9 at 110mpr on streets and rims. After the cams and slicks my best has been 13.7 at 104 mpr and yes thats after trying 2 new tunes from AM. So next week the cams are coming out and going back to American Muscle If they dont want to give me my money back they can just keep them.
