It may or may not be. It could be adjustable with a spring change. Either way, I doubt you will have an issue.The only time it should be opening is when there is excess pressure in the pipes and the throttle is closed. By the way - I don't see a vacuum line going to the top of the BOV, but I could be missing it.

 

im still in the build process, the car is on jack stands and there is no line currently going to the BOV.

This weekend i will finish running all the vacum lines and tidy up everything, and then all i will have left before i hit the road is depowering the steering rack FM style.
