Thanks for your response. I want to run a pump gas 444 and was looking at 9.75SCR/7.28DCR for a start with 6X-8 at 100cc wondering whether limiting boost to 10psi and strengthening like I mentioned would keep me from having pre-ignition/detonation issues … or blowing the heads off from too much pressure
Wondering if people are just cautious when adding boost and what is the real issue causing breakage/damage. Too much cylinder pressure loosening things up or ignition at the wrong time?. Was going to drop serious coin on a set of factory heads now, it will be a while before turbo, at least a season. I have a nice set of 7M5 cores that can be taken from between 114 to 104cc.
I saw you had blown a head gasket and you upgraded with a new radiator that solved heat problems. Am not sure I can make 1 set of heads do "double duty" but would like to try. Iron heads will hold more heat, I think you said you have aluminum. I think newer boosted motors use mostly aluminum heads and have computer controlled "knock" sensor systems that change the timing slightly to control possible damage from pre-ignition. I think even non-boosted applications have both those. There must be systems to retrofit our motors. Well I have to get my NA DQ's going first
Hey I see you said you were running on long island, I have delivered there many times, did you ever have occasion to go to Brooklyn and meet Nunzi?
