Hal, I have a Panoz road race car with 351 Winsor with a Caton multi trap door
oil pan. Currently it also has two
oil sensors, one sensors goes to a Auto Meter analog guage and the other to a Stack data acquistion system. I noticed on several occasions while racing, after installing the Stack system that the
oil pressure would drop from 60lbs to 6-8 lbs just long enough to trigger the low oil pressure alarm on the Stack system. But the analog guage barely moved, I didn't think much about it until I burned a couple of rod bearings and stuck a connecting rod through the pan. I have installed now " Poor man's dry sump" the Accusump , problem solved. If you do any high speed work, long hard corners, I highly recommend, much cheaper than a rebuild. Thanks, db
