Default boost pressure and timing?

I have head studs and marine hg. On my 12 valve was wondering with that set up whats best for boost levels and highest timing? I plan on going with twins when i save up. Will i be able to run higher boost with twins rather then a single? Jw so i don't blow a gasket

as in compund turbos? yes you will get more boost with 2 turbos. stock bolts can take up to 45psi from what ive read i wouldnt trust them above 30. but im guessing you have arp studs?

Yes and a marine head gasket. Just wondering how much boost withi a single I can go and how much with twins. I know twin produce less drive pressure which is what kills the head gasket so i assume twins I'm safer with running alittle higher I was thinking 60psi it should hold? And how far can I time it? I was thinking *17 would be good

boost is just a number. how much volume are you planning on running? what size turbo. if you didnt do anything to your head other than a new gasket i wouldnt push my luck past 40psi. 40 psi on a s300 is totally different than 40psi on a s400. timing depends on what you want your truck to be. but without rings in the head i would stay below 18*

I plan on running a d tech 64 from diesel power source for now then putting an s475 bottom to make them twins

---AutoMerged DoublePost---

For d tech on its own it says around 1190cfm and almost 1900cfm w the s475 as a bottom for twins
