SOLUTIONS 

                                  

MS RACING COMPONENTS formed in 2013 set out to develop a line of tools to allow easy piston to valve clearance measurements on late model engines utilizing variable valve timing (VVT) technology. 


‚ÄčThe MS RACING COMPONENTS VVT UNLOCKER TM  replaces the OEM VVT cam gear phaser valve bolt or OEM VVT oil control valve during camshaft degreeing and piston to valve clearance measurements. Shop compressor air is used to unlock the VVT cam gear phaser. After piston to valve clearance measurements are verified the MS RACING COMPONENTS VVT UNLOCKER TM is removed and replaced with the OEM VVT cam gear phaser valve bolt or oil control valve.

                                                                                                                  

MS RACING COMPONENTS currently offers a patent pending VVT  UNLOCKER TM  for the 2007 - 2013 LS based GM engines using VVT technology.    

                                       

MS RACING COMPONENTS currently offers a patent pending VVT UNLOCKER TM  for the 2014 - UP LT1/L83/L86 based GM engines using VVT technology. 


MS RACING COMPONENTS currently offers a patent pending VVT UNLOCKER TM for the late model Chrysler Hemi engines using VVT technology.


MS RACING COMPONENTS is currently developing a patent pending VVT UNLOCKER TM for the FORD Modular 4.6L/5.4L and Coyote engines using VVT technology. Availability 2016.




 

   


HOW IT WORKS

MS RACING COMPONENTS

MS RACING COMPONENTS formed in 2013 set out to develop a line of tools to allow easy piston to valve clearance measurements on late model engines utilizing variable valve timing (VVT) technology. 

 

VVT cam gear phasers are computer controlled using pressurized engine oil. Without oil pressure, the VVT cam gear phaser is locked   advanced making piston to valve clearance measurements in the full cam retard position impossible.


The high performance aftermarket currently offers VVT cam phaser limiters. However actual piston to valve clearance measurements are not known using these limiter kits. Using the MS RACING COMPONENTS VVT UNLOCKER tools with the available limiter kits VVT piston to valve clearance can now to accurately measured! 

 

Upgrading to a high performance camshaft with increased duration/lift piston to valve clearance becomes an issue especially with the exhaust valve when the cam is fully retarded. Piston to valve clearance can't be verified in the full retard position since the VVT cam gear phaser is locked. Setting up your new high performance cam has never been easier with VVT UNLOCKER TM.   

The MS RACING COMPONENTS VTT UNLOCKER TM  is also extremely useful when aftermarket piston combinations are used. More aggressive custom cam profiles can be spec'd since accurate piston to valve clearances can be verified with the VVT UNLOCKER TM. 

 

The MS RACING COMPONENTS Patent Pending VVT UNLOCKER TM

allows for quick and easy unlocking of the VVT cam gear phaser without damage. Unlocking the phaser allows the phaser to be turned to the full retarded position allowing for accurate piston to valve clearance measurements to be taken. Piston to valve clearance measurements can be checked at any position relative to the crankshaft.
