LDS-427 turbo

[stb64]

47 in Hg = 23 psi. Get the HP48sx calculator for your android phone. It has all of the conversions built in. Who said that they didn't make much boost?

I was under the impression 47InHg is roughly the same as 23.5 psi

I wasn't that far off then. Knowing that 1psi is about 2 InHg is close enough for me. I will have to go by that anyway, as I don't have an android. It would be cool to test the 4D-454C on my LDT engine (would have to swap the intake elbow, and air cleaner pipe, and make an exhaust adapter), or test it on my (currently 4-450 equipped) LDS427-2 engine.

I thought the big turbo would only make about 8 psi max in real world testing?

That is what I have heard also. The "C" turbo would go to 7 psi and the "D" turbo would go up to 8 psi . If you jacked up the injection pump you could get up to 12 psi boost.
