Massive oil leaks.

10second pulls. Not 30minutes down the highway. This is a crankcase ventilation issue. Also the installer drove the car quite a bit to make sure no leaks. He never ran it hard enough to get the pressure high enough though. The installation is not the issue.

Have you called the engine builder to see what he has to say?
On the first fire up on the dyno he should have ran the motor at one giving rpm ( 1800- 2000 rpm) for ten to fifteen minutes to break in the cam and get some heat into the engine before putting any pulls on it. Did he do that?
