Default ATI plastic air box-maxed out

My plastic ATI air box exploded yesterday after a few runs at 10 psi. I guess thats the maximum pressure the plastic one can take in case anyone wanted to know.

The plastic air plenum before the intake, I really don't like how its setup....

In the future I'll probably be running some 3.5"-4" piping up to the TB

I've been running 10lbs. and had no problems so far. Did it explode like a firecracker was inside or just split a seam or something?

my plastic intake tube blows off the throttle body sometimes under about 10 lbs of boost. If not under a lot of boost, it does it when it shifts. I think that the blow off valve cant get rid of the pressure fast enough. Any suggestions?

Silver-whistler: is your box bolted down to the radiator support plate? I had the same problem until I did this. I had the metal box at first but had to switch to the plastic because the metal one was messing up the airflow and throwing the computer off. I think ATI may have stopped selling the chrome box until they figure out why.
