... I don't think I ever put a HP number on the 6 PSI boost limit I have been talking about, with stock internals! .


Back to the orig. topic of this thread, .... I don't think I can "attach" a HP figure to the 6 PSI boost level, ... for the reasons mentioned above, ... unless you are speaking about a totally stock engine, with the turbo added. ... thren your figure is about right. (stock ex system KILLS the add-on turbo), ... it really needs to be upgraded at the same time!!

I think the main question is if one wants to put a Hahn turbo on a stock engine without adding heavy duty engine pieces, what was the safe amount of boost and what HP does that correspond to? I gather from your comments that it is, indeed, 6 psi, which would yield around 30 HP on a totally stock system. A non-stock freer flowing exhaust system, cold air intake, and other non-HD mods would likely boost that HP figure, which is a plus.

I think some folks want to put on a turbo but not go with the rebuild of the bottom end, etc., and want to have an idea how much boost and HP they can safely gain thereby. Thanks.
