great info Jeremiad, I learned something . I don't own anything that new, doubt I ever will , but I understand what is happening there. Yet with todays so called advanced tech , they let stuff like this go ? my 12.5 / 1 396 had alot more compression than this and never blew anything out. What about a trap like a kitchen sink has , when it gets full then a light goes on in the dash telling you to open a valve and it will drain back into the pan. Whatever works I guess, but seeing the issue , I would say yeah , put those cans on guys.
