what pressure is the mini coolant at ?

 

Radiator test pressure up to 21.75 PSI, WARNING don't go higher, I would guess that anything higher may cause it to burst or rupture seals.

Radiator cap test pressure 14-18 PSI

So from that I am assuming a 14 PSI cap is OEM.

 

thx dude /. i'm running a 16lb. ; should i drop to 14 ?

 

I think your in range, leave it alone.

 

awsome !!! i got an alluminum resevoir from seven enterprises . it's gorgeous . beautiful welds . but i don't think they're offering them any more . i put a 16lb. cap on it . it's really nice work . i'll snap a pic tomorro .
