To answer your question.. I would be a bit nervous beyond 30 seconds if run at an idle. Really nervous if run beyond a minute. But I should clarify; I am kind of a nervous guy when doing something really stupid. Oops...probably offended someone with my humor....so: Sorry!

Leads me to ask: Are you asking because you are just pondering the question or plan to or did?

Don't do it.

Best plan.
