My vette that I run on road courses has a dry sump holding 10 quarts and my temp even with a large cooler can really get high due to the RPM's. Per chevy engineer I went to a higher viscosity oil to reduce the possibility of shearing.
Higher temps will stress the oil and require more frequent changes. Maybe a larger oil cooler if you do that run often.
If he is running synthetic, the higher temps will not resent a problem. Hell, airhead motors which I have had in the past, would laugh at 240 degrees.
