Had that issue years ago on Pettis's dyno and I foot-balled the filter but didn't burst. I run low pressures street/strip w/zero issues running 5w3-10w30 and larger than some bearing clearances past 7000 and just peek in a Pro-Stock car on the line...........15-20 lbs at idle is what I personally saw when I freeze framed Erica's car last year but who knows up top...........
