I used a 7 gallon primary bucket for some 1.084 Tripel and WLP550. Huge krausen. Plugged the airlock, then blew the lid off. Had yeast all over the ceiling and walls. That was on day 4, after making the mistake of giving the yeast a swirl to encourage them.
That particular recipe had 2 pounds of cane sugar. It makes the yeast crazy. Maybe T-58 is better-behaved. I don't recall any fireworks when I've used it.
