Saab Intercoolers

[Nattman82]

Hey. Toying with the idea of winding up my boost a little on the S12 but im worried about blowing the intercooler to shreds. Its a Saab item with the plastic edges (not sure of the rite terminology) clipped to the metal centre (again with the wrong words, total brain fart today).
Anyway, anyone have a rough idea of the maximum boost these type of intercoolers can take? Obviously im not going to wind up to stratospheric pressures but im looking to up it from its standard 0.6BAR to 1BAR.
I have a t25 turbo fitted and the engines in good condition so im not expecting any big problems from there. Its not going to be a permanent thing just a once in a while going for a drive kind of thing.
