for that long. :) Glad to hear everything is ok though. I suspect you dont have EGT's. :) If you did, you probably would have backed off a little. :) 850C is about the max you want to see and you'd want to keep it below that for long runs. But the VG is tough as nails and with oil cooled pistons, it seems to have an amazing amount of tolerance to high EGT's. The inconel exhaust valves are harder than hell, even at 1500F, opening and closing 50 times a second. :)
