Tial Q BOV Spring

[Vmax4creed]

Looking at the Tial Q BOV, for a Apex super charged application the spring chart says green spring for s/c, Has anyone ran this? wondering what is the max boost rating on the spring?

I haven't ran that one though. I like the vortec blue one, ( https://vortechsuperchargers.com/co.../maxflow-race-bypass-valve?variant=7813347457 ) It opens at 10-11 in hg vacuum and that helps keep the MPI blowers alive and increased mpg slightly over other BOVs available. At least back when I bought it a decade ago lol.
