well guys, the oil restrictor (.063 orfice) is on it's way. For the time being I changed my oil feed line. The old one was a 4an and i just put in a 3an. It made a bit of a difference but in heavy acceleration oil still spits out. Do you guys still think that there is to much pressure? Lmk, also if anyone has the same setup, I would like to know if you had any of these problems. Thanks guys, more info would still help. I will keep everyone updated.

^^^Or your CHRA is mounted too low. They don't require a ---- ton of pressure or flow. Only about 700cc per minute is needed.
