    That makes a whole lot more sense. So this is the solution to something ENTIRELY different from what your BOV prevents.

    Thanks guys.

    It's also what kills upgraded CT's, or any turbo with a turbine too big for the housing size.

    No I just modded the springs in the BoV's so they're more responsive to Off/On throttle and that cured my issue.

    I don't know if Kristel still has the vid of when I took her for a drive but it was surging like mad during that run.

    I do, but it's on a disk somewhere... You need me to try and find it?

    Epic build is on hold whilst I try and finish my degrees... Only 12 more months of hell to go!

    It will make less power then a non ported cover as well.

    Look at the location - you're not in the 'pressurized' portion of the intake - you're just inside the inlet where compression begins.

    Tissimo, you've got back to back runs to show this?

    Slightly less power and more lag is a good trade off for not having a turbo grenade (or grenading your engine because of it, look at the dyno in that vid...)

    Im still learning about turbos/surging but am i correct in assuming if i run my stock (responsive BOV) with an aftermarket BOV like a Tial will this prevent surging?
