2011-2014 FORD 5.0L CAM PHASER VARIABLE LIMITERS

Livernois Motorsports is proud to introduce another exciting new product for the Ford 5.0L Coyote engine. The original cam lockouts were built with the goal of preventing failure of the cam phaser. They do an excellent job of this and cure cam phaser issues, however they do limit the engines ability to retard the cam timing and as a result, cause a small loss in power at high RPM. In most cases we are talking 10-20HP depending on the application. That loss in power was worth it, given the gain from using aftermarket springs and cams was double that number. Not to mention, with power adders vehicles making 600+ RWHP, the loss of 10-20 HP was small for the gain in durability and ultimate assurance that the cam phaser would not fail causing possible engine failure. If the phaser is already bad, installing the limiters won’t fix the noise, so a full lockout may be your only choice.  Note: Tuning is required after installing this product.

The next step in this evolution comes with this new limiting version of the same lockout. Simple in design and requiring no special tools to install, the limiting lockouts allow for the phaser to retard the camshaft still but limit its travel to only 20 degrees maximum. In most cases max power can be found in the 8-14 degree range of retard, so by still allowing up to 20 degrees of camshaft retard, the ability to get maximum power from cam phasing is available. The limiter mechanically locks after 20 degrees and prevents any further movement. This allows for use of larger camshafts with more lift and duration and prevents piston to valve issues. The other benefit that goes with the limiter is that it prevents the noise and durability issue from becoming a factor. By reducing the volume of oil and limiting the total travel rotation of the phaser the issues with noise and failure of the phaser are eliminated.

THIS PRODUCT IS INTENDED FOR HIGH HORSEPOWER OUTPUT APPLICATIONS THAT ARE GOING TO BE DYNO TUNED, NOT F-SERIES TRUCKS IN A NOISE REPAIR SITUATION
