PISHTAS turbo build

max boost seems to be speculation at this point. i have yet to see anyone push the stock setup to the point of failure on propose. there are instances of head gaskets letting go in the event of the tune going out of wack momentarily but i havent read about anyone actually throwing a rod or melting a piston yet. it also depends on the application too, dd, race car or somewhere in between. if you only need it to hold together for one run and only most of that one run, it would probably hold 30psi. not gonna be good for much after that but if the head gasket doesnt lift im pretty sure it would hold. now like Serj22 said, a slant will live happily at 10psi indefinitely and the slant is pretty darn happy there. it ive been to 20psi with my setup but i turned it down recently to get the tune a little better. i will be turning it back up very soon and plan on seeing what my current turbo can actually push without falling off. should be close to 30psi. i have a spare slant ready to go so im looking to find what it will actually hold with a good tune.

dont bother boost referencing the stock pump. unless you only plan to run a maximum of 5psi.
