Stock Turbo Efficiency?

I am wondering what the max boost efficiency is of the stock turbo charger. I can hit 49 psi right now. I plan on doing a twin setup soon that uses the stock charger.

Over 40 your pushing hot air. Its a good thing these turbos are tough or it would be BOOM at those pressures. FYI, don't lift suddenly at 49 psi too many times ory ou won't be using it in a set of twins.

:agree2: 35-40 psi is efficient as it gets.

not sure but anytime you use a stock charger in a twin setup, get a drive pressure gauge, if its gets to high, bye bye headgasket...

It is adjustable on the secondary turbo (top).
