I have been running the external
oil pump with a wet tank. I have never changed or had any issue with the dry sump belt. I was thinking about going to a dry sump tank. I was quoted 1500.00 to build the tank. Plus, I would need a different pump,
oil pan and lines. As Rick said, dry sump is the all out best way to go. Anyway, I just pulled the motor apart after many really hard track miles. The bottom end looked good, plenty of
oil to the bearings. Based on that, I am staying with my existing oil set up. I have the external oil pump, an accusump, and return lines from the valve covers to the oil pan. It seems to be working for me, just another way to go. Scott
