Drain oil back to the inlet from what? Both hoses go to the top of the canister. Both hoses are in good condition as well. I think part of the reason its not pulling to hard at the upper rpms is the insane boost its trying to push. Lots of hot air, and I'm sure the drive pressure at that rpm with the turbo spining that fast is out of this world. That little .36 exhaust housing cant flow that kind of air.. I'll let you guys know what i find when I get it off there.
I'm thinking while its off a T-4 compressor housing upgrade!
