here's the page (about halfway down):

TPC Racing ATP:2 turbo kit DIY Install - Page 2 - 6speedonline.com Forums

does the aos need vacuum or just a lower pressure than in the crankcase (ie, ambient, but vented to a catch can)? i thought connection to the intake plenum was not for vacuum but to recycle any 'oily discharge' for emmissions reasons.
