Good afternoon all,
Since FCS I have upped boost & fuelling and am now peaking at 28psi.
What I am noticing is that after a hard run the coolant is being pressurised. First thoughts of course are HG issues, however there are no other signs of this (stable running temp etc.)..
I have read on plenty of occasions that high boost pressures can 'lift' the head, momentarily forcing exhaust gases into the coolant system. Could this be what is going on?
I then did some further reading and have found a few 'fixes'.. The most promising one was this guy who fitted an automatic air bleed valve (like the ones found on central heating systems) to the top radiator hose. What this valve does is let out any air/gas whilst not allowing fluid to leak, effectively stopping pressurisation.
Any thoughts? Maybe I should change the HG and perhaps swap to ARP studs.
