UPR Products F150 update for the 2.7L and the 3.5L Ecoboost engines. After substantial testing, we've found there is a definite performance improvement from running a check valve on the clean line from behind the throttle body where the vehicles gets the primary vacuum for evacuating the crankcase and the WOT line where the primary vacuum comes from during Wide Open Throttle evacuation. To get the very best performance and vacuum control we installed the UPR Pro-Series™ Check Valves which react much faster and flow 4X as much as the standard check valves do. This is part of the evolution of the system as we continually test and work on many variables to tune the most out of the system.Hey Joe, I have been doing a lot of research on your catch can, as I have just purchased a 2.7 EB and I’m still unsure of a couple things. Can you explain what the PCV Delete is? Also, is there a concern of any residual oil vapor that passes through the DVCC, although small, getting sucked into the WOT line that was drilled and going into the turbo?
I have updated all the test vehicles and many customers have switched to the new UPR Pro-Series™ Check Valves and have reported similar results with crisper response and improved oil collection from the increase in vacuum.
I can be PM'd for details as we are working on a special package for all our enthusiasts to be able to move up and improve the efficiency of their PCV system.
