Improve. If you're looking for your next upgrade, Comp Cams Stage 1 XFI VSR Camshafts are a significant improvement over your stock camshafts. It's hard to improve on an already impressive engine. But Comp Cams delivers with these camshafts, dialing up maximum HP and improved throttle response.

Maximize Top End HP. With two different designs to choose from, Comp Cams has got you covered. Compared to the Stage 1 NSR series, these Stage 1 VSR cams deliver more power in the higher rpm ranges and maximize your top-end and overall HP. The NSR series does not require new springs - to get the incredible top-end power of the VSR series requires a spring upgrade.

Compatibility. These camshafts are designed for the 2005-2010 4.6 and 5.4 Modular three valve V8 Mustangs.

Tech Notes:

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

Ask a Question

Where would I go to get these Cams tuned? Is there a product on the site that can tune them? Also, how would these pair with the Stage 1 E-Force Supercharger?


Is it necessary to use the CAM Phaser Limiter? I'd rather retain all of the VVT function of my engine, as well as save the $200 dollars. But if that isn't possible, i'd rather just stick to my stock camshafts.


  • The phaser limiter is a required item to go along with any camshaft made from Comp Cams to help eliminate the piston to valve clearance issues.

Will these cams be good to use with the Roush R2300 550 hp supercharger - Phase 2 kit. Also does bama have a tune for this camshaft?


  • These will be a good camshaft to use with the R2300 Roush Mustang. However, Bama does not have a tune for this camshaft.

Can you use this camshaft with the roush R2300 550 hp supercharger - phase 2 kit. Also does bama offer a tune for this camshaft?


  • You can use this camshaft with the R2300 Roush however BAMA will not be able to tune for this cam as they do not offer tunes for spring required cams.
