that is stock, has no wastegate, has a 1.15 ratio exhaust housing and a 1.10 ratio intake housing. stock engines produce 15-19 psi boost.... lives a good life up to 25-30 lbs of boost.
past that they tend to come apart thanks to a thrust bearing set-up vs a ball bearing.

well hell I thought they where good up to 40PSI? I'm making 26-27PSI now and my stage twos will be here in a few days.. so am I going to blow that thing for sure? or will short busts of higher PSI not hurt it any?

30 is just about the limit. It only took a little over a month for me to wipe out the thrust bearing on mine with BDP stage I's and 32 psi. Beans D66 holds up to II's and I know of at least one person who is running one with 530 hybrids
