? about coolent recovery

Well, guys last week I made it down to the local track, for some runs. Well It was a very busy night to say the least, everybody was there. The staging lanes took about 45 min to get to the front on the line. And that is only if there was no cleanup involved in between runs.

Well sitting in line for my second pass I noticed the car getting hot. I was sitting in line with it off. Only starting it to pull forward as needed. I noticed it was hot once I got to the front of the line and I tried to start her and she had a harder time turning over. But at that point it was to late.

The way the staging lane are design at the local track is once your in line there is noway to turn around without everyone behind you moving. So I told my self to just make it down the track, then park it to cool.

I did the burnout, staged, launched, All was good till 60ft smoke everywhere.

The system had built up to much pressure and blown the top Rad. hose off.
laying coolent on the track pissing everyone and thier mother off. Delaying the track runs for about 45min while they cleaned up.

My ? is currently I run a coolent chrome recovery bottle from Summit that is NOT vented, Could this be my problem. Should my coolent recovery system be vented to vent off the built up pressure.

What I was thinking is that. If it was vented it would have caught the overflow of the coolent, but vented off the high pressure at the same time preventing my hose from blowing off.

Please help me out, The car never had cooling problems before on the street and everything else checked out fine. I run a single elec. fan and it seems to be operating properly. I'm thinking of also replacing my 180* therm. with a 160* unit.
