Fantastic build thread! Thanks for sharing all the info you have done. I am going to take some of your idea put into practice and use them as well.
That is one amazing X1.
I did have a question, have you noticed any excess oil usage due to the track runs and using the JB4?
I read that the JB4 produces up to 23psi which seems like quite a bit and I was concerned about engine longevity, but with you running full track days at that boost level without issue, I thought I would ask.
