Max boost

What is the max boost a stock CA18DET intercooler can take?

My car was on the dyno last with a broken exhaust manifold gasket and boosted .6 bar

I fixed the gasket on thursday and had the car out for a run this morning.
Its nice and chilly outside and this was the first time I really milked the car since the gasket fix.

The car was pulling stronger than ever and my back stepped out in the whole rev range in second gear. Couldn't get third coz then all hell broke loose!

Car died on me...

limped home and when I lifted the hood I popped off two boostpipes.
That was the easy fix but then the car still didn't run well. So I started testing the pipes one by one and when I got to testing the IC I couldn't believe my ears. It was leaking. Some how I popped the IC.

Could I have popped the cooler on .6 to .8 bar?

It shouldnt pop at suck low boost, infact I've never heard of on popping. Maybe a defect or it got damaged somehow?

I ran my sx at 0.8 bar with the stock cooler for a while before I fitted the bigger cooler. I had no problems with it. Like sokar says, it must have got damaged somehow.

i got a cooler for you...

two in fact.

1. stock - with all piping.

2. custom - 610x350x360 - or something like that. its a big fat porsche cooler with custom end tanks. no piping.

i found a pic of an s14 cooler once, the dude ran about 2 bar and then hit the nitrous - the thing basically exploded its end tanks!!!
