Can anyone tell me what the boost pressure on a 1972 7GB track loader with an Allison 6-cylinder turbo charged engine should be?

It's not an ALLISON engine. It's an Allis-Chalmers engine. I assume it is a 3500 series engine ?? There's a metal tag on the left side of the engine block. I would expect a max turbocharger/intake manifold boost of 10 or 11 psi at full throttle under a good load.

Hi Dr Allis what would boost be for following 3, 11000 HD11 engines 1 HD11EP Bosch PSB fuel pump, TO6 turbo 2 HD11EP Roosa pump, TO4 turbo 3 HD11 series B; Robert Bosch inline pump, TO4 turbo. Full load is 'around' torque converter stall speed on these engines; all powershift models' Curious what boost would be for them Thanks Merv.
