Is this idea different in turbo diesels (vs. turbo gassers)? In the gas world, that is an absolutely impossible idea. NEVER will you have the exhaust pressure come anywhere CLOSE to intake pressure. In my 944 Turbo, with the stock K26/6 turbo, you are likely to see 45+psi in the exhaust for about 18psi in the intake. But of course that is with the stock turbo (running slightly higher than stock boost). This is the whole game of turbo efficiency for a given application...and why 1psi DOES NOT EQUAL 10hp - and all these other crazy theories. It all has to do with efficiency of the turbo. I guess people don't realize that at a given psi, different turbos can run as much as TWICE the cfm as others.
