well guys here is the dyno video, there is some oil smoke right after its shut down.. I am thinking its pulling some oil past the rings as soon as the throttle blades close.. any thoughts on it? thanks for checkin it out!

Do the chickens have large talons?

On a n/a car:
smoke on WOT would likely mean rings
smoke on coast down mean valve stem seals
I would imagine a turbo engine is similar but do you have a well thought out PCV/breather arrangement? You may get some smoke as the engine returns to a vacuum state due to build up of blowby gasses in the crankcase from the PCV closing due to boost. Yours definitely smokes on coast down.

Love the sound of a turbo!! Are you going to post any of the numbers from the dyno or were these for tuning only? How does it feel out on the road?
Nevermind, I just saw your other post with the info I asked about. Great numbers.

I've seen this before - our problem wound up bieng a drain on the turbo was not straight enough for the oil to not hangup in it. I haven't seen any pictures of your setup but in one of the vids the turbo looks to be sitting at a slight angle vs. the ground. Got any pics of it?
