Hi All,
I just got my new thermometer today and have been taking some measurements.
What I'm wondering is, when you exceed the maximum compressor efficiency of a turbo it goes into like a "subsonic" mode where it just heats the air up and you start losing hp. A 300zx hits this around 12 PSI of boost.
What I want to know, what is the maximum an intake temperature can be before I start LOSING horsepower?
My max temp at the throttle body hit 67 degrees C at 5psi with no intercooler. I have other numbers as well, but I don't want to make this into a novel.
