5 years on this setup, stock engine, 500+whp for 3-7 track days a year.

Yea I agree it will be fine at 260, but I just feel that is somewhat high. But if its lasted this long at that level, then it should be fine. Like I said, that's just my personal preference to not run higher than 240 degrees or so.
