My buddy has been running around 35psi max on his NA 7.3 for like a year and a half now. He daily drives it as well. He has an RD150 that hits closer to 190cc on the bottom end and tapers down to like 156cc according to the calibration slip and has had no problems. Additionally, he is running the RD Stage 3 kit with stage 2 turbo and a Typ4 cam. It is a strong running setup.

thank you. That's what kind of experience in was looking for. Any videos of it running? I'm going to be making my turbo purchase soon so wanted some first hand results. I have a very similar build as far as motor work

I'll get some videos from him. Also look on the Facebook pages for older posts. There are some posts there. There is a guy running an S368 and RD150. He's been running that for over 2 years. There are some other guys as well. Just have to search a bit.

Yup, and remember, it's not the boost pressure that bends rods, it's the (much) higher cylinder pressures that burning a greater quantity of fuel with that added air that does it.
You could run 40 psi of boost without more fuel than N/A and it wouldn't make any difference bending rods wise(Of course, actually making that boost might be hard...)
Now, 15-20 PSI of boost, at the 200-250RWHP level is something that can be done without head studs for a longer period of time(at least a year) without blowing head gaskets. Beyond that, well, not sure. I don't have something beyond 250, so I can't say.

That means nothing until the "guy" can state he has 250,000-300,000 miles on his engine running it at 25lbs. boost with no internal problems in all that time. I'm more inclined to believe the results Ford engineers stated they found when overboosting their turboed 7.3's in test stands. Continual overboost equaled eventual wallowed out wrist pin bores in pistons.

The Power Stroke Rods are used in some of the builds when building a high HP Engine.
They are a beefier Rod, some machining has to be done to them to fit.
Not sure what they do to the Wrist Pins and Cylinder bores.
Lots of claims out there, show us the proof.
I found a 5-spd Shift **** at PNP Friday, now my T-19 has one more gear.
