Finding Turbo Limits
Finding Turbo Limits Kind of a generic question, but, what sort of data would one keep an eye on to indicate a turbo out of steam?
I have a old PT76gts and currently run ~15psi on a 383ci gen 2 LT1.
I would like to see how far I can push it and was just getting information before I do something dumb. Plan is just to add air and not touch timing. (its fairly lazy, combined with a fat 10.5afr in PE)

I'd say air temps going nuts or with a 383 the backpressure has got to be real high by now. If you have good fuel you might be able to close the gate and see what the turbo makes, but I doubt you will get to a really high boost number or at least not up top.

Ability to make and hold boost
pre-turbine pressure.
Compressor discharge temps
Honestly just hoping to get it to push 20psi and perhaps squeak out 800/800 area

Haven't bought one in a Looooong while, but there was a LED tach gadget you could buy from big diesel suppliers that went on the cold side and measured the speed of the wheel, all you had to do was tell it how many blades and install it per the directions.. Was pretty simple. They had them on some generators I used to "own" as part of a building I took care of..

Why complicate this? When you turn up the boost and make no more power, your turbo is maxed out. Efficiency will have left the scene long before that, but the window was closed on efficiency the moment you decided to max out anything.
