It's really easy to reattach when it's hot, and that way you avoid high temperature shutdown...

I see what you're getting at in wanting to protect your turbo but if you were to HEAR your engine in that situation I don't think you'd want to do that. (Leave it running in neutral till you put the hose back on - that is.)
It would be screaming at higher revvs than you ever thought possible
But then - looking at eleblanc's photos now - It is not clear to me that it is in fact the
venturi/vacuum side hose that came off.
Here's how those hoses sit on my simple little B engine:
Disconnecting that hose marked "vacuum side" is what causes my engine to immediately scream up to its revv limiter.
It now looks like eleblanc disconnected the other side - which actually gives no noticeable effect on my engine
. (I say this because of where his hose (that came off) connects to his injector pump diaphragm housing. Bearing in mind that his intake manifold is considerably different to mine - so looking at it alone - I would be unsure which would be the venturi/vacuum connection on it.)
PS. This thread is what triggered me to experiment by removing my hoses. I'm going to read it again now just to make sure that I'm recalling correctly what I learnt then. (Alzheimer's could be doing its dirty work?)

(Hmmmm. Whatderyerknow. I was recalling correctly.
