rattle at full boost

[mildtowild]

only when i am at full boost a get a metal on metal rattle. I have only had it a couple of days and have replaced the ic pipe (somehow he thoght electrial tape would hold boost) with a metal one. This would be my first guess of course but i doo have clearence between the pipe and turbo/IC. any other thoughts?

That is what it sound like to me you didnt here it before becuase you were probably low on boost.

Is this common on a stock motor? If not what would the likely culprit be?

also realted or not, I blew out chunks of either my Cat or muffler(i hope) so i would not doubt if it was pretty clogged.

My first thought is detonation too. You need to keep out of boost until you figure it out or you very well may be blowing more than muffler pieces out of the tail pipe!

If electrical tape was holding your turbo to IC pipe together, I wouldn't doubt that your intercooler pump is NOT working.... high intake temps = detonation. Take the cap off and check for movement in the coolant.

You really need to get Datamaster so you can get a handle on boost/AFR's/timing... a fuel pressure gauge is also a good thing to have handy with these trucks.

So i pulled my battery and noticed that the vac line to the wg soliniod was off. I am no expert but i would venture a guess that no wg = to much boost.

You might find this page for new owners useful: http://www.powertuneplus.com/syclone/howto_stock13s.shtm It talks about these type of common problems including your problem of a loose WG hose causing too much boost. So you're definitely right that "no WG = too much boost."
