I was attempting to be conservative with a 15-20 lb boost .. Is it your experience that 25 lbs is completely safe with the appropriate intercooler ? .. I have seen many intercooler options .. There are two main camps W2A and A2A intercoolers .. One camp says that A2A are more reliable from the standpoint of no plumbing but are 30% better depending on how you cool the water .. I would like to lean towards the more reliable / safer side if possible and if I could have a system whose boost is adjustable from 15 - 25 lbs of boost without mucking with the injector pump or injectors all the better .. If all I have to do is a minor adjustment to the injector pump and I can then run 20-25 lbs then this is the safer path .. I have been reading that the most efficient A2A intercooler runs in front of the radiator but fans should be used to decrease the temperature of cool air .. Should I also consider a triple layer high efficiency engine coolant radiator as well ? .. Again, my reasons for all these modification is to improve upon reliability & increased longevity ..
