Chris I would not worry about the plastic. If the manifold will hold vac then it will hold pressure. I'm not saying it would hold 1,000 lbs. but then you arent going to put anywhere near enough pressure on it to burst. You would be surprized at how much pressure it would take to make it fail.
I am just talking crap here, but... I am pretty sure that the manifold is designed for vacuum. Probably something like .75atm max. 1 atm=16psi??? so there is 4psi maximum pushing in normally. When you add the turbo you will have ~6-8psi or more (chris?) above the 1 atm so there will be atleast 6psi pushing out, plus the air temperature will be much hotter. This just seems bad to me.
