When I installed the 3.12 pulley, I had Sharif retune it....very conservatively.

I normally hit between 10.1 - 10.5 max.

A litle rich is a little safer.

My tail pipes are really black.

 

Cool, you've been a great help so far. I was a bit low on oil when I checked earlier this week(good thing I have an ARC oil pan which takes an additional 1-1.5 quarts). My car is high mileage...close to 85k miles.

Is there any way to visibly inspect the blower for a bad seal? Or do I have to disassemble it?

Yeah my Ings rear skirt has my Fuji tips slightly tucked in, so the whole rear bumper gets REALLY dirty b/c of tip placement.

 

Check pipes and intercooler for oil. Also look underneath the blower to see any oil stains. If not, you're good to go.

If you pull an intake tube - and see any oil, you'll know.

also - an easier check would be the bypass valve. If you have a filter on it, check it and see if it has oil all over it or the areas behind it and around it are oily/filmed. If so, then there is oil in your intake and then oil coming past the blower seal.
