Be careful when you add extra oil to your sump. A little is OK, but if you add so much that the oil level is up into the crank you'll have problems. When the crank is whipping all that extra oil up it doesn't just cost you power, it also makes the oil hotter, and adds lots of air bubbles to it. Not good, but neither is loosing oil pressure in the corners. Baffles are your friend.
BTW - I read an article about testing oil pans/baffles. As your oil is pretty much at the same viscosity as water when it's hot you can use water to see what happens to the oil in your engine when you corner. In the article the guy tested stock and modified pans/baffles. He enlisted a buddy to sit in the passenger's seat of the car. Then filled the oil pan he was testing with the proper amount of water and handed it to his buddy to hold as the car was driven like a madman around the corners. Yea, without baffles the water just sloshed out. Messy, but representative of what hot oil does when you corner. Of course the oil doesn't spill out of the engine when you corner, but it does get into the spinning crank. And if enough gets sloshed up into the spinning crank, you loose oil pressure. Again, baffles are your friend.
