In keeping with our goal of providing our customers with the best possible value, we have tested a large group of components specifically designed for the 05-08 Mustang GT 3 Valve Motor.
We have invested hundreds of hours evaluating and refining each of the new 4.6L 3V products on our MD Chassis DYNO, and at race tracks coast to coast to ensure that we would develop as much power as possible, and as safely as possible.
The site menu on the left side of this page, lists the clear winners when it comes to “performance vs. dollar” value. Please check back often as we are always testing and developing new ways to create more horsepower.

COMP Cams® Ford 4.6 & 5.4-Liter 3 Valve Modular Camshafts
Add up to 48 more horsepower with equally impressive torque gains
The Ford 4.6L/5.4L Modular 3V Ford Mustang engine has become increasingly popular, so now the question is - how can we further improve the performance of it? 
COMP Cams® has built upon Ford’s technology with three new series of camshafts created specifically for these engines: Each series of cams is available for
both naturally aspirated and supercharged engines and is carefully matched with COMP Cams® components, including high performance valve springs, retainers and COMP’s
latest offering for these engines – the Cam Phaser Limiter Plates. Don’t settle for stock; make your Ford Mustang stand out from the crowd.
The performance secret behind the COMP Cams® Ford 4.6 & 5.4-Liter 3 Valve Modular
Camshafts is the application of the COMP Cams® technology. By focusing on
what they wanted the valve to do at specific rpm rather than simply the camshaft profile, COMP
Cams® engineers were able to increase the amount of time the valves were open and generate
improved area under the curve, netting huge power and torque increases.
COMP Cams® camshafts provide the biggest power and torque improvements, from idle to redline, of any
sub-300cid engine they have tested.

XFI™ NSR (NO SPRINGS REQUIRED) FORD 4.6L/5.4L MODULAR 3V CAMS
The COMP Cams® XFI™ NSR (No Springs Required) Cam Sets for Ford 4.6L/5.4L Modular 3 Valve Engines are the first truly “drop-in installation” camshafts ever created for this popular application – striking the perfect balance of performance versus installation difficulty. Offered for both naturally aspirated and supercharger-equipped engines, these cam sets require no additional computer re-tuning; however testing has shown that mild tuning can result in power gains even greater than the normal 25 rear wheel horsepower. These camshafts are fully compatible with the factory variable cam timing (VCT) system and are designed to operate in the stock rpm range. The stage one cam set is designed to maximize mid-range power and torque, while stage two maximizes top end horsepower.
Net power increases up to and as much as 25 +HP increases over stock levels.

What are cam phasers?
Ford’s cam phasers are specially designed, computer-controlled cam gears for all 2005 and newer Ford Modular 3 Valve engines that have the ability to adjust camshaft position while the engine is running. Since the modular engine uses two camshafts, two cam phasers are used.
How do they work?
Engine oil is pressure fed to the cam phasers through a series of passageways in the cylinder heads and camshafts. The engine computer controls a pair of solenoids that adjusts this oil flow into and out of the cam phaser’s control chambers, giving the ability to retard the cams up to 60 crank degrees.
Why did Ford put them in the engine?
When the cams are retarded 20-40 degrees during part throttle engine operation, it takes less power to turn the engine over. This helps to increase the engine’s fuel efficiency. Another power benefit is that the cam phasers allow the camshafts to always be in the best position for maximum power, regardless of what the engine’s rpm is. The engine makes more torque and horsepower and extends the high rpm powerband by an extra 800-1000 rpm.
Why should I modify the cam phasers with a COMP Cams® Limiter Kit?
If there is a downside to the stock cam phasers designed by Ford, it is that they have such a wide range of movement. Since the cams can theoretically be retarded by up to 60 degrees, there is very little piston to valve clearance in the engine. This minimal piston to valve clearance limits us to fairly small cam profiles with very little overlap.
What does the COMP Cams® Phaser Limiter Kit do?
These limiter plates replace the factory back-plate on the cam phaser. They have posts which extend into the cam gear’s control chambers, limiting their movement to no more than 20 degrees. This gives more piston to valve clearance and lets you install bigger, more powerful camshafts with safe piston to valve clearances. While keeping up to 20 degrees of movement available, all the wide-open throttle benefits of the cam phasing are retained, since the normal retard the cams see at wide-open throttle is only around 9 degrees.
Do I have to reprogram my engine’s computer after installing the Cam Phaser Limiter Kit?
Yes, you MUST reprogram your engine’s computer for the engine to operate properly after installing the cam phaser limiters. The guidelines for reprogramming are simple – just make sure that the maximum retard amount entered for any of the cam phaser tables and DTC strategies in your tuning software does not exceed 20 degrees.
