I recently had my car modded (BTR stage 2 cam, pulley, intake, long tubes, offroad x-pipe, 103mm tb, ported blower and heads, auxiliary fuel pump, catch can, 100 octane tune). It put down 815whp. I'm noticing a distinct oil odor that's present only during WOT pulls and goes away right after the pulls finished and isn't present just cruising. I don't see any oil in the catch can looking through the sight glass. I'm wondering if it's possible the smell is coming from the vent on the catch can? I can't see any leaks. Anything else I should do other than continuously monitor the oil level and hope for the best?

If it is a Mighty Mouse catch can with filter element on the top then it is very possibly its from higher crank case pressures under high engine loads.
In that case this would be considered normal operation.

It is the one with the filter on top. I contacted them asking if that smell is a normal occurrence with their catch cans so we'll see what they say. I'm just praying the smell isn't from oil being consumed.

I have nearly same set up. I don’t have much smell while driving or at WOT. When I shut car off and park in garage I definitely smell oil/ fumes until air clears.

Mighty Mouse got back to me and said crankcase smell (oil) is normal during WOT but should not be present while normal cruising. I'll just keep monitoring my oil level and hope it's not from consumption.
