Cerbera Boot Vents & Cabin Pressure

[CerbWill]

I've seen a few threads from jonbarrett around the 2008 time about the problem of windows being pushed out at speed, e.g. http://www.pistonheads.com/gassing/topic.asp?h=0&a... The cure seemed to be some venting underneath the rear screen and under the boot which was introduced on later cars (I have a '96 with the under rear screen vents but no others) to reduce cabin pressure build up at speed. As the info is now 8 years old the photos have disappeared, does anyone have any photos of the boot vents on their car?

I've got a vent into the boot behind the helmet holder, not sure if that's normal, same type of vent that you have by your knee and under the centre of the dash. Normally have a window open so no idea if it stops the Windows popping though.

Interesting, my car definitely doesn't have that.

Hmmm I wonder if there's some vents to the outside in the boot or wheel arches to go with that link between the cabin and boot. I'm not sure how just linking the cabin and boot would fix the problem. BTW my vents under the rear screen have foam stuffed in them. Anyone else's like that or are they empty?

I had a look around a mk2 Cerbera this weekend and it didn't have the vents under the rear screen as far as I could see. I wonder if there's several different versions of a venting system along with some crossover mixtures as would be typical of TVR.
