[QUOTE="jeffs, post: 15981584, member: 54343"] So if you have 1 oil source feeding 2 turbos, I'd guess you'd need the orifices to keep a little bit of pressure to each line going to each turbo, otherwise the oil would just take the easiest path, and at that point you'd be hoping that the easiest path would be somewhat equal to both turbos at idle, and at max rpm? I don't think the orifices are used in this application to limit oil flow to the turbos, but rather to keep some back pressure on the lines forcing an equal flow to both lines when they split. Also if the oil feed lines into the turbo were large enough and without any restriction, you're motor could actually starve for oil. For myself I see another reason to go single turbo after reading this. Too bad you couldn't have a dedicated pump to feed the turbos a constant, and consistent flow of oil at all times. It's Probably not feasible, but there's those oil-less turbos that seam to be working fairly well for some people, but would probably be a hell of a chore fitting them onto your existing kit. I'm also having trouble buying that you're breather system doesn't flow enough to relieve excess pressure from the crank case, unless there's alot of blow-by, but I think you'd have an oily mess on your valve covers if that was the case. I hope you get this figured out, I'm sure it's a frustrating road. If it was me, I'd try running the oil lines with the restrictors on them into a bucket at idle with one line alot higher than the other, and with the engine at idle keep drilling the restrictors out until you start seeing a difference in oil flow, and stop there. Just don't rev up the car with no oil going to the turbos, and put something in the impellers to stop the turbos from spinning while you're testing the oil. [b][U]AT IDLE![/U][/b] [/QUOTE]
